Ethernet Crossover Cable Basics

24 Jan 2018

cable, installation, cabling, Washington D.C.The crossover cable connects two Ethernet network devices to each other. They were invented for temporarily supporting host-to-host networking when a network router or another intermediary device is not available. Although crossover cables appear the same as a standard straight-through (patch) Ethernet cable, their internal wiring structures are different.



Straight Through vs. Crossover


A straight-through cable is used for connecting two different kinds of devices, such as a network switch to a computer. In contrast, a crossover cable is for connecting two devices that are identical.


The straight-through cable’s ends can be wired in any manner, but both ends must be identical. This is different from the crossover cable’s internal wiring, which reverses the signals for receiving and transmitting. The first and third wires and the second and sixth wires are crossed.


High-quality Ethernet crossover cables have special markings which allow users to distinguish them from straight-through cables. They are often red in color and the word "crossover" will appear on its casing and packaging.



Crossover Cable Needs


Crossover cables came into use during the 1990s and 2000s because the most common types of Ethernet were unable to support direct cable connections between hosts. Intended for using specific wires for both receiving and transmitting signals, the original and Fast Ethernet standards required the communication of two endpoints through an intermediary device to avoid conflicts.


The Ethernet feature MDI-X has auto-detection for the prevention of signal conflicts, enabling the Ethernet interface to automatically determine and negotiate the expected signaling convention of the device at the other end of the cable. The majority of home broadband routers and Gigabit Ethernet adopted MDI-X.


As a result, crossover cables are only necessary for the connection of two Ethernet client devices if they are not configured for Gigabit Ethernet. Nowadays, Ethernet devices are compatible with crossover cables because they can automatically detect them.



Ethernet Crossover Cables Usage


Crossover cable usage should be limited to direct network connections. When a user tries connecting a computer to an antiquated router or network switch via a crossover cable rather than a standard cable, the link can be prevented from working.

Advantages of Upgrading to Structured Cabling – Part 1

4 Jan 2018

Structured cabling, data cabling, network cablingIf it has been a while since your company has upgraded your network cabling, you and your team may not be achieving your potential. As you know, an organization’s IT network is the very heart of its operations. Lacking a network that is up-to-date, staff members will not be as efficient and productive as possible.



Updating from Point-to-Point Cabling


The update that yields the most benefits is having your network make the transition from an outdated point-to-point cabling system to a far more effective structured cabling system. As you may know, there are only two ways for transmitting data over network cables. Numerous companies persist on using point-to-point cabling. Unfortunately, it tends to become problematic, especially when a company needs to significantly expand the network’s size and capabilities. Let’s dig deeper to understand the reasons.


Point-to-point cabling directly connects a switch, device, network, a server, or network, to another network component via fiber optic cable. For the last few decades, this wiring method provided an innovative way to swiftly build a network. However, during that period, the majority of networks at IT departments were not large.


Nowadays, as networks expand and speedy transmissions of massive data amounts become routinely expected, the maintenance of outdated point-to-point cabling systems, along with the thousands of cables required for operations, becomes a large burden on a company’s IT resources.


As a result, organizations have transitioned to structured cabling systems. Rather than directly connecting every single network component to another, a structured cabling system directly links storage units and servers to a communication backbone.


Installed in every part of a facility, local cabling panels are linked to the communication backbone with only one cable. This enables users to easily connect their devices to the whole network by connecting a cable to the nearest cabling panel.


Part 2 will discuss the advantages of upgrading to Structured Cabling.

Structured Cabling’s Top Ten Tips

31 Dec 2017

structured cabling,Washington DC New York CityStructured cabling that is properly installed can help your business grow by helping to improve its network performance and IT capability. The following will discuss structured cabling’s Top Ten Tips for installing cabling systems.



#1 Cable Labeling


Although cable labeling will slow installation, it will help save lots of time and effort during future repair, reconfiguration, and maintenance tasks.



#2 Cable Testing


Ensure every cable is tested and confirmed to be functioning properly during the installation process. A cable with a nominal performance should not be utilized as it may decrease overall system performance.



#3 Short Patch Cables


Do not use long patch cables when they aren’t required. They are inefficient, look disorganized, and are prone to tangling.



#4 Select Quality Terminations


Avoid purchasing cheap terminating cables because time will be unnecessarily spent on troubleshooting in the future. Select those that are of high quality and terminate properly and rapidly.



#5 Avoid Overheating


Keep in mind that maintaining proper cable temperatures to avoid overheating is crucial for stable and reliable network performance.



#6 Measure 2X, Cut 1X


Precise measurements prior to cutting will minimize damaged and wasted cables during installations.



#7 No Kinky Fiber Cables


As fiber cables have great flexibility, they can kink bend, and knot. These will result in flaws in the fiber cables, negatively affecting performance of the network.



#8 Maximum Cable Length


Do not exceed the maximum length of a cable run, which is typically 100 meters for network cabling systems.



#9 Allow for Expansion


Network cabling systems should always have room for interior expansion. As a business grows, its network should have the room to be able to upgrade or expand.



#10 Qualified Installation Company


In order to ensure that a company’s network cabling system will be properly installed, management must select a qualified installation company and request references.  Their technicians should be BICSI certified and experts in ANSI standards.

Basics and Benefits of Zone Cabling – Part 2

14 Dec 2017

network cabling,cat6 cableAs mentioned in Part 1, zone cabling designs provide benefits in materials savings, decreased installation times, and easier MACs (moves, adds, and changes). Part 2 will continue discussing the basics and benefits of zone cabling.



Designs


Experts recommend CAT 5e and 6 UTP (unshielded twisted pair) zone cabling topology with a connecting block system within the ZE (zone enclosure). This configuration will render unnecessary the stocking of factory pre-terminated and tested interconnect cords for connections in the ZE, simplifying cable management through the elimination of cable slack.


Please note that CAT 6A UTP media is not recommended for zone cabling due to reasons involving performance and flexibility. UTP cabling is vulnerable to crosstalk in particular installation scenarios. In addition, it is not the best media for supporting remote power applications with loads of 30W or more. Because CAT 6A UTP zone deployment is dependent on modular connections inside the ZE, connections provided by pre-terminated and tested interconnect cords need to be available for rapidly enabling MACs. Affordable shielded zone cabling solutions are recommended to address these situations.



Cost Savings


Even though more CAPEX (capital expenditure) will be necessary for a zone cabling installation, assessing total costs should also account for OPEX (operating expenditure). The performance of MACs is classified as OPEX, and studies by Siemon found there are hundreds of dollars in savings from each move, addition, or change when using a zone cabling design versus a traditional cabling design. Their study also discovered a tipping point when ROI begins accruing from utilizing a zone cabling design.


IT (information technology) needs for many organizations evolve constantly, which requires being able to quickly reconfigure floor space. An improved capability of supporting MACs will allow owners of facilities to achieve considerable ROI benefits from deploying zone cabling systems in a two to five year period. According to Siemon, the combined costs of CAPEX and OPEX for zone cabling designs will be invariably less than traditional cabling designs


Part 3 will continue discussing the basics and benefits of zone cabling.

The 5 Most Common Structured Cabling Errors – Part 1

19 Oct 2017

Structured Cabling, cablesStructured cabling systems are so standardized that good practices should merely entail following ISO/IEC, CENELEC or Telecommunications Industry Association (TIA) documentation for panel and outlet standards, cable pathway standards, maximum cable and patch cord lengths, patch testing standards, etc. Strictly doing so will invariably result in an installation that is professional and trouble free. In addition, as data speeds grow faster and faster, following industry standards becomes even more crucial.


Improperly installed cabling made up of shorter runs, which do not overly stress the system, may function well enough. In addition, data speeds may be quite beneath the cable specification capacity. As an example, CAT5e carrying 100Mbps and capable of 1Gbps will have ample margin of error. However, structured cabling systems still need qualified technicians for proper installation supporting maximum data speeds over the entire network as required.


The following will discuss the five most common errors of structured cabling. Remember to call an experienced and expert cabling installation team to get the best results for your company’s project.



Error No. 1


Considering cables as merely wiring is the first error. They are actually very important electronic components that provide the pathway for data from point to point within a network. These points may be a desktop PC, a network switch, server, router, and wireless access point. When you consider that cables make these connections possible, then you can understand how important it is to make sure that the cabling is of high quality and properly installed.



Error No. 2


Running data cables near power cables is the second error. Even when cables are screened, this practice is unsound. When data cables are running near and parallel to   power cables, noise emitted by power cables may infiltrate data cables. As the load carried by power cables fluctuate, resulting spikes or surges may radiate into the data cables, creating undesired noise decreasing the quality of the data transmission.


Part 2 will discuss three more common errors of structured cabling.

Fiber Optic Cabling for Your Business – Part 2

14 Oct 2017

Fiber Optic Advantages


Cabling, network cabling, cable InstallationsAs discussed in Part 1, fiber cables provide a number of advantages that make them superior to copper cables. This includes longer distance effectiveness, greater bandwidth capacity, resistance to electromagnetic interference, safer usage, and stronger security. Part 2 will discuss how fiber optic functions, its two main types, and fiber networks.



How Fiber Optic Cables Function


Fiber optic cables transmit data through the generation of pulses of light by light-emitting diodes (LEDs) or lasers. A fiber optic cable is composed of either a single strand or several strands of glass, each measuring slightly thicker than human hair.


The core is located in every filament’s center, and it is where light travels. Covered by cladding made of a glass layer, the core is able to reflect light inward, preventing signal loss and letting light travel through the cable’s bends.



Two Main Types


There are two main types of fiber optic cabling, single mode and multimode. Using extremely thin glass filaments, single mode fiber optic uses a laser to generate pulses of light, while multimode utilizes LEDs.


By utilizing the technique of Wave Division Multiplexing (WDM), single mode fiber networks raise the volume of data traffic transmitted over a filament. Combining light at various wavelengths is termed multiplexing, while separating them is called de-multiplexing. Thus, several streams of communication can be transmitted on a single pulse of light.



Fiber Networks


The installation of the majority of fiber cabling is intended to support long distance connections between national and international geographical locations. However, a number of internet service providers (ISPs) have made investments in the expansion of fiber to provide direct access to homes in suburban neighborhoods. These are termed "last mile" installations.


FTTH (Fiber to the Home) services, such as Google Fiber and Verizon FIOS, are becoming more common. They can provide homes with gigabit (1 Gbps) internet speeds. Direct fiber cabling runs directly from a main office to a single client, providing maximum bandwidth. In contrast, shared fiber cabling is ultimately distributed among several groups of users who are in close proximity.

Fiber Optic Cabling for Your Business – Part 1

8 Oct 2017

Technology,Network Cabling, cablesThe widespread use of fiber optic cabling stems from 1950s research. These studies eventually made transmitting visible images via glass filament possible. This new technology was eventually used for viewing instruments and remote illumination for surgery. Subsequently, George Hockham and Charles Kao successfully achieved data transmission through glass fiber in 1966.


Fiber optic cabling is composed of glass fiber filaments housed within insulated casing, and these cables were designed for long distance, large capacity, and high performance data networking and telecommunications. In comparison to wired cables, fiber optic has high-bandwidth capability and is capable of data transmission over longer distances. Due to these properties, fiber optic cabling is used for a great portion of telephone, internet, and cable television systems around the world.



Fiber Optic Advantages


Fiber cables provide a number of advantages that make them superior to copper cabling. Due to properties of high bandwidth and low-loss, fiber optic cabling can be utilized over much greater distances than copper cables. Fiber optic cables can run up to 2 kilometers for data networks without repeaters. This is because light can travel much further on fiber cable and still retain its strength.


Fiber optic cables have greater capacity. Through the use of multiplexers, a single fiber optic cable can have the same network bandwidth as several hundred copper cables. It is now standard for fiber cables to be rated at 10 Gbps, 40 Gbps, and 100 Gbps.


Although it has special shielding as protection against electromagnetic interference, copper network cable is still susceptible when numerous cables are close to each other. This is in contrast to the physical properties of the glass used in fiber optic cables.


Fiber optic is also safer to use than copper in volatile spaces, where sparks can lead to disaster. It also has the upper hand in terms of security because tapping fiber cable to steal data transmission is very difficult.


Part 2 will discuss how fiber optic functions, its two main types, and fiber networks.

Cabling Tips for Data Center Management

1 Sep 2017

Network Cabling,Washington DC, New York City, Atlanta GAWhenever there is an IT systems issue, the resolution can often be delayed by poorly structured cabling. Enterprises often turn to their IT staff or an electrical contractor for cabling, but they would be wiser retaining a professional cabling service with years of experience. The following are important cabling tips for data center management.



Highest Quality for Budget


As expected, higher quality cabling materials are more costly, but have superior performance. For example, gold connectors have greater resistance to corrosion, but they will also be more expensive than lower-quality connectors. If your firm’s cabling will be difficult to access or located in a corrosive environment, cables with gold connectors will be the right choice.



Cabling Capable of Company Volume


Category 5, 5E and 6 are cable types and each has its own capabilities in terms of the amount of data carried, speed of transmission, and distance covered. Consult with a professional network cabling service to discuss your present and future requirements in order to select the proper cabling.



Fiber Optic for the Future


Companies expecting large data volumes in the future or requiring longer distances should select fiber optic cables. Retain expert cabling professionals because fiber optic installation will entail particular requirements that can be complex.



Accurate Measuring for Planning


When the recommended span is exceeded, cable becomes more vulnerable to distortion, degrading data quality and speed. IT staff with limited experience may not properly measure the entire distance by not accounting for corners or obstacles.



Margin for Future Modifications


The office may be reconfigured or cable connections may be moved in the future. Thus, it would be wise to allow some margin for future modifications by providing plentiful slack for each cable installed.



Labeling for Organization


An IT team should know precisely where a cable starts and terminates. Clear labeling enables faster tracing of faults, minimizing downtime and resulting losses in revenue. Cabling service professionals carry out proper labeling as a matter of routine.

Structured Cabling’s Six Subsystems – Part 2

28 Aug 2017

structured cable management,DCAs mentioned in Part 1, a structured cabling system is a type of open network structure that can be used by data, telephony, access control, building automation, and other systems. Its advantages are operational flexibility and economy. Part 2 will describe each of structured cabling's six subsystems below.



The Six Subsystems


1. Entrance Facilities


Entrance facilities house the protection devices, network demarcation points, cables,  connecting hardware, and other equipment that connect to private network cabling or the access provider. Connections between the inside building and outside plant cabling are included.



2. Equipment Room


Featuring environment control, the centralized area for telecommunications equipment is typically more complex than a telecommunications room. Usually containing the main cross-connect, it may also house the horizontal and intermediate cross-connects.



3. Backbone Cabling


Backbone cabling provides the interconnections between entrance facilities, telecommunications rooms, equipment rooms, etc. Typically, backbone cabling is comprised of fiber optic cables, intermediate and main cross-connects, mechanical terminations, and patch cables utilized for backbone-to-backbone cross-connections.



4. Telecommunications Room


Housing the terminations of backbone and horizontal cables to connecting hardware with patch cords or jumpers, a telecommunications room may also house the intermediate cross connects or main cross connect for different portions of the backbone cabling system. This space is a controlled environment containing telecommunications equipment, connecting hardware, and splice closures.



5. Horizontal Cabling


Extending from the work area’s telecommunications information outlet to the telecommunications room, the horizontal Network Cabling consists of horizontal cables and mechanical terminations, along with the jumpers and patch cords located in the telecommunications room. The system may also incorporate consolidation points and multi-user telecommunications outlet assemblies.



6. Work Area


The work area’s components typically extend from the telecommunications outlet/connector end of the horizontal cabling system to the work area equipment. At least two telecommunications outlets should be installed in every work area. If utilized, multi-user telecommunications outlet assemblies (MUTOAs) are a component of the work area.
