ETHERNET CABLE PERFORMANCE SUMMARY
Cat-6 - This cable is defined in TIA/EIA-568-B provides a significant improvement in performance over Cat5 and Cat 5e. During manufacture Cat 6 cables are more tightly wound than either Cat 5 or Cat 5e and they often have an outer foil or braided shielding. The shielding protects the twisted pairs of wires inside the Ethernet cable, helping to prevent crosstalk and noise interference. Cat-6 cables can technically support speeds up to 10 Gbps, but can only do so for up to 180 ft - even so this makes them relatively long Ethernet cables.
The Cat 6 Ethernet cables generally have 2+ twists per cm and some may include a nylon spline to reduce crosstalk, although this is not actually required by the standard.
installations of structured cabling begin with written specifications for each system component. Specifications ensure that you purchase and install the right product for every job. Specifications also guarantee all products offered are equivalent in a competitive bid situation.
Teltech Cabling follow specifications written by electrical consulting engineers.
Choosing a fiber optic cable for any given application requires considering two issues, installation requirements and environmental or long-term requirements.
Installation requirements include where and how the cable will be installed, such as pulled in conduit outdoors or placed in cable trays in a building. Long term requirements need to consider moisture or water exposure, temperature, tension (aerial cables), or other environmental factors.
We use to contact several cable manufacturers (two minimum, three preferred) and give them the specs. They will want to know where the cable is going to be installed, how many fibers you need and what kind (singlemode, multimode or both in what we call "hybrid" cables.) You can also have a "composite" cable that includes copper conductors for signals or power.
Since the cable plant design will call for a certain number of fibers, consider adding spare fibers to the cable - fibers are cheap compared to installing more cables. That way, you won't be in trouble if you break a fiber or two when splicing, breaking-out or terminating fibers. And consider future expansion needs. Most users install many more fibers than needed, especially adding singlemode fiber to multimode fiber cables for campus or premises backbone applications.
