Every installation is performance tested using industry approved equipment to ensure the highest levels of integrity.


Our services include consultancy, planning, installation and testing of the following network categories

Category (Cat) 5e

Category 5 cable, commonly referred to as Cat 5, is a twisted pair cable for computer networks. The cable standard provides performance of up to 100 MHz and is suitable for most varieties of Ethernet over twisted pair. Cat 5 is also used to carry other signals such as telephony and video.

Category (Cat) 7 Cabling

A Category 7 cable (Cat 7 Cable) is a type of shielded twisted pair cable used in high-speed Ethernet based computer networks of 1 Gbps or higher. It is defined and specified in the ISO/IEC 11801:2002, Class F specification. The Cat 7 cable is backward compatible with Cat 6, Cat 5 and Cat 5/e cabling standard and equipments.

Fibre Optics (single mode/multi mode)

Single Mode cable is a single stand of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. Single Mode Fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310nm or 1550nm. Carries higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width. Synonyms mono-mode optical fiber, single-mode fiber, single-mode optical waveguide, uni-mode fiber.

Single-mode fiber gives you a higher transmission rate and up to 50 times more distance than multimode, but it also costs more. Single-mode fiber has a much smaller core than multimode. The small core and single light-wave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.

Category (Cat) 6

Category 6 cable, commonly referred to as Cat 6, is a standardized twisted pair cable for Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards.

Cabinets & network accessories

Once you figure out if a rack or enclosure best suits your needs, there are still a number of options to weed through until you find the best fit. One of the first things to consider is where you are going to put your network equipment. Do you want it on the floor? On the wall? Perhaps even mounted to the ceiling?

Data Cable management

Along with cooling, cable management is one of the most pressing challenges encountered by network installers. Even a cursory internet search will turn up countless examples of cabling disasters, with network cables looking like messy spaghetti. This isn’t the way it has to be.

Tackling your rack cable management during set-up and installation of server cabinets will ensure that it’s easy to expand, reconfigure and perform maintenance without having to worry about unplugging the wrong thing or navigating through the tangled cables.

Why Choose PCL for your Structured Cabling





Downtime !

With an unorganized messy cabling infrastructure, mistakes are commonly made. Incorrect ports are unplugged. Even worse is the messy cabling that gets in the way. Trying to remove a single cable from a large tangled mess can cause stress on the other cables. This stress can lead to network and channel errors in the hardware that are very difficult to trace.

Airflow: If a point to point method is used, the front and potentially the sides of the switch are congested with cabling bulk. This impedes the airflow that the switch needs to operate. This also translates to underfloor cooling; cabling congestion in this space hinders the airflow of the CRAC unit and can cause cooling issues.

Once again, organization is the key word here. With an organized structured cabling system the benefits are:

  1. MAC’s are much quicker due to the fact that they are done in the MDA versus running long patch cords from equipment racks.
  2. Potential for downtime is reduced as potential for human error is drastically reduced due to this organization.
  3. Time savings; cable and port tracing becomes a much easier job with a structured cabling system.
  4. Aesthetics; Never underestimate the looks! A structured cabling system will look much cleaner than a point to point method. Since the changes are done in the MDA versus at the hardware, the hardware can be cabled up and not touched in most instances. This allows the cabling in front of the switch to remain aesthetically pleasing.
