Data Center Cabling Best Practices – Part 1

4 May 2017

Structured Cabling, Washington DC, New York CityModern data centers are equipped with devices and networking equipment that connect them. These devices demand increasingly greater bandwidth, and so their fiber or copper cabling must perform at a high level. Today’s data centers must be flexible, scalable, reliable, and manageable, making best practices required.

Planning the Infrastructure

Thus, documenting the existing and planned network, along with its equipment is needed. A flexible patching structure will permit the interconnection of devices at desired locations.

Structured Cabling

The structured approach of cabling revolves around the design of runs and connections that ease cable identification, maintenance, repair, and future expansion or reconfiguration. A Main Distribution Area (MDA) and Horizontal Distribution Area(s) (HDAs), along with two-post racks that permit improved access and cable management, will be needed.

MDA and HDA components must be of high quality and capable of bearing expected future loads. Their layout should have horizontal and vertical cable managers. The MDA contains primary cross-connects and core networking equipment. The HDA contains the cross-connects for the distribution of cables to Equipment Distribution Areas (EDAs). Patch cables will connect servers and storage by utilizing patch panels at their respective EDA.

Next, the equipment racks inside the data center must have their layout determined. A horizontal cabling configuration will be used for the distribution of cables from the HDA to the EDA. Flexible connectivity is required by a dynamic data center environment. The goal is the implementation of a system that transmits fiber channel, Ethernet, and other protocols.

Future port and application requirements will also need to be considered. Expansion and technological advances must be anticipated, so the installation of ports and cabling needed in the future should be done now to save on labor costs and downtime if upgrades are needed.

Structured Infrastructure Benefits

  • Cable identification and fault isolation simplified

  • Consistent cabling lays sound foundation for future

  • Future expansions and modifications made easier

  • Standard-compliant components from multiple vendors possible

  • Flexible connections provided

Cabling for Modular Data and High Density/High Port Count Fiber Equipment will be discussed in Part 2.

Is it Practical to Use Cat6 Cable?

26 Apr 2015

cat 6,structured cabling, Data CablingData volume has grown extensively. Also, the processing capacity to users continues to get grow. Specialists in data management forecast that information production will be 44 times larger in five years with enterprises needing to process and safeguard 80 percent of the new data.

Data Cables

For these reasons, you might need to become more familiar with different types of cabling. There is Category 5 (Cat5) cable but it is only capable of transmitting 1000 megabits data rate per second on an Ethernet network. Transfer of data demands are increasing due to new and more sophisticated applications. That is why many companies prefer to work with Category 6 (Cat6) cables. Cat6 has a maximum data transfer of 10,000 megabits per second. Cat6 is also backward compatible which means your Cat5 connectors will plug i and work (at the lower speeds).

Future Proofing

Cat6 infrastructure guarantees that your system will be relevant well into the future. This allows users to easily cope with any modifications, new features or technological developments. The Cat5 standard has been used for a long time. However, your enterprise needs adequate bandwidth to handle these continuing and future changes. It is not merely a possibility or “let's say” situation. It is to be anticipated as the online experience continues to progress.

Demand for Cat6 escalates as the world-wide web is now offering premium video streams, online applications, highly-responsive and media-heavy portals.  If you decide to upgrade to a more reliable network, consider Cat6 cables. It is fast becoming the new standard in this industry.


Cat 6 is more costly compared to Cat5e cables. On average, we are finding that projects cost about 20-25% more. This is because you are not guaranteed full speed unless all the components operate at gigabit speed. So, you need Cat6 cable, connectors, patch panels and Gigabit switches too. If one part is not rated as gigabit, the network will run at Cat5e speeds. Call or contact us to help you make this decision.

Nevertheless, experts say Cat6 will sooner or later surpass Category 5e.  And the initial upfront costs will pay future productivity gains for many, many years to come.


Directions in Telecommunications and Cabling

3 Apr 2015

 Data Cabling ,Network cabling, DCThe telecommunications industry continues to advance. And bandwidth demands will continue to increase. Meanwhile, conditions to convey considerable amounts of information quickly are changing. Applications including graphic information, technical modeling, video conferencing, and multi-level online databases will certainly increase bandwidth requisites. The bottom line is demand for higher transfer speed for information is expected to rise.

Properties for Cabling Systems

Two principal properties needed for cabling systems are performance and easy installation. Fiber and shielded twisted-pair provide stronger signals compared to Unshielded Twisted Pair (UTP) although these two lagging in client acceptance. The question is will UTP provide the appropriate bandwidth for modern applications?

Unshielded Twisted Pair

UTP is considered the most prevalent cable worldwide for telecommunications and networking. Cat 5e is the most popular and it long ago replaced coaxial cable which failed to keep up with more dependable and faster networks. UTP is also easy to install, develop and troubleshoot. Unshielded Twisted Pair cabling does not have any foil covering. It depends on twisted pairs inside the cable to prevent electromagnetic interference. UTP is used extensively for local area networking and comparable cabling configurations. Hence, installation is easier and less expensive.

Shielded Twisted Pair

Shielded twisted Pair (STP) features a metallic foil enclosing twisted wire pairs inside the cable. This is the safeguard against electromagnetic intervention which facilitates rapid data transmission. STP functions by drawing electromagnetic interference and counterbalancing this with grounded cabling. The drawback is that if the cable is not grounded correctly it loses the capacity to prevent unnecessary noise. STP is also larger and more sensitive compared to UTP cables. Expert cable installers use this cabling for industrial environments where adjacent equipment emit significant amounts of elctron-magnetic interference (EMI). Actually, UTP and STP can perform well if installed and maintained by efficient cabling providers.

Transmission is Essential

Transmission should be balanced. This is the standard for conduction of data using twisted cabling pairs. Separate protection for balanced twisted pairs is designed to enhance resistance and emission of the communication lines. The shielding method produces a conductive barrier that lessens these electromagnetic waves. It also creates a conduit for conduction so that currents and can pass data through without any obstruction. Shielding can be performed on individual pairs or as one set of pairs.

Simplifying Your Office with Network Cabling

28 Jan 2011

Network Cabling ConfigurationInstalling network cabling in your office will result in a number of added benefits but it’s what networking will eliminate that could have the biggest impact in some environments.  The increased speed, increased performance and added security of a network are amazing attributes, but the ability to instantly share pertinent information is a feature that can truly enhance office operations.

In order to share programs or data in an environment where PCs operate independently, data needs to first be transferred to a back up medium before it could be shared with other users.  Employees would have to take the time to copy an important file or program to a CD or disk and
