During your consideration of the kind of cable that should be selected for your IT network, several factors come into play. One of the decisions you will need to make is whether to use copper or fiber optic cabling.
Copper certainly has plusses. It is already installed in numerous sites and is less costly for connecting network components. Although fiber optic cabling has a higher price tag, it has key advantages that make it more attractive than copper for creating structured cabling infrastructure.
The following are five reasons why most cable professionals select fiber optic over copper cabling.
Fiber optic cables have longer service lives than copper, decreasing maintenance costs and downtimes from replacements. Although fiber optic wires are made of glass, copper wires are more susceptible to being damaged.
When evaluating the transmission of copper wire to that of fiber optic, the contest can be simplified to the comparison of the speed of electrons to the speed of photons. Although C transmissions do not move at the speed of light, they are still extremely fast by moving just 31% slower than the speed of light!
Over long distances, fiber optic cables will undergo much less signal loss than copper. This quality is termed “low attenuation.” Due to attenuation, copper cables are capable of transmitting information up to a maximum of 9,328 ft, when it then loses power. In contrast, fiber optic cables are capable of transmissions up to 24.8 miles.
If improperly installed, copper cables will generate electromagnetic currents that result in EMI inside nearby wires, which can cause serious problems throughout a network. On the other hand, fiber optic cables are not conductors of electricity.
Fiber optic cabling is safer because it won’t be a fire hazard. The reason is no electrical current travels through fiber optic cables.

As discussed in Part 1, network cabling installation errors may result in long-term problems and high costs. They can be avoided by following standard structured cabling practices. Continuing with the discussion of typical network cabling installation mistakes, Part 2 will cover Ignoring Regulations, No Testing, and Skimping On Labor.
There are codes, laws, and ordinances that regulate low voltage cabling, and they vary, depending on the municipality, city, and state. Experienced professionals who install network cabling are knowledgeable about the applicable requirements and how to complete a project to code. When the fire marshal or building inspector determines laws were broken or wiring is not up to code, a company can be penalized with large fines and required to remove and reinstall cabling if it is a fire hazard.
When network cabling is installed, each cable should undergo testing. This should also involve the verification of a cable’s length and specifications. This process is crucial because it will confirm whether or not the network satisfies project specifications. The data also provides a basis for future testing and troubleshooting, along with supporting any warranty claims.
Considering how important the network cabling installation is to the future, cutting corners in the hiring of cabling installers is unwise. It is crucial to always verify the qualifications and licensing of the cabling installation company you are considering. Make the time and effort to check each reference that is provided. This may save your company time, money, and problems if you avoid working with an outfit that provides substandard services support. Request the contact information of previous customers who had projects similar to yours and get their opinions before making a commitment. Finding an installer that is the right fit for your project is the first step for ensuring a successful network cabling installation.

During the process of selecting a cabling installation company, you will meet with candidate contractors at the new office space. Each visit will typically be a free consultation as each contractor they will make a site survey in order to make an evaluation and prepare a quote for the project. Below are items and information a business owner should be ready to provide to make each site survey as efficient and productive as possible.
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.
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 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.
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.

As discussed in Part 2, there are considerable cost savings from the deployment of zone cabling systems. Part 3 will continue discussing the basics and benefits of zone cabling.
Perfect for smart and green building designs, zone cabling systems can reduce labor expenses and waste of cabling materials. Centralized connections inside ZEs achieve greater efficiency for the routing of pathways. LEED credits provided by the United States Green Building Council (USGBC) can be maximized. In addition, cable sharing can support several low-speed and low pair count applications functioning on a single 4-pair cabling system. This achieves greater efficiency in cable and pathway utilization.
Modern workspaces are becoming more social and flexible, and they are increasingly reconfigured and updated with greater frequency.
Zone cabling systems allows flexibility in work spaces, facilitating faster and less disruptive moves, adds, and changes than traditional cabling systems.
Zone cabling allows for greater efficiency in the use of pathways and materials, which is required for smart and green building designs.
CAT 6A shielded cabling is recommended in zone cabling designs to achieve maximum performance.
Shielded CAT 6A zone cabling designs result in greater performance, better support of remote powering applications, and ZE termination flexibility at practically no additional cost in comparison to CAT 6A UTP designs.
Regardless of size, zone cabling installations planned with 25% spare port availability will considerably decrease client disruption and allow the facility owner to recover the expense for extra ports inside two to five years or after achieving the threshold for ROI.

As 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.
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.
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
