CAT 5 Installation

Category 5 cable is an Ethernet network cable standard defined by the EIA and TIA. CAT 5 cable contains four pairs of copper wire and supports speeds up to 100 Mbps. CAT 5 is the fifth generation of twisted pair Ethernet technology and the most popular of all twisted pair cables in use today.

CAT 5e is the enhanced version of CAT 5 that adds specifications for far end crosstalk. CAT 5e supports networking speeds of up to 1000 Mbps.

JT Low Voltage specializes in CAT 5 installations. We take pride in our work, ensuring that each CAT 5 project meets TIA/EIA-568-B standards.

What is the difference between CAT 5 and CAT 5e?
Both CAT 5 and CAT 5e have 100 ohm impedance and electrical characteristics supporting transmissions up to 100 MHz. The differences between CAT 5 and CAT 5e show in all aspects of performance: capacitance, frequency, resistance, attenuation, and NEXT. CAT 5e components were designed with high-speed gigabit Ethernet in mind. While CAT 5 components may function to some degree in a gigabit Ethernet, they perform below standard during high-data transfer scenarios. CAT 5e cables work with ATM and gigabit speed products. Simply, if you are using a 100Mbps switch, get CAT 5e cable instead of CAT 5.
Is CAT 5e backwards compatible?
Yes it works with any 10BaseT or 100BaseT network cards and hubs. CAT-5 is also upwardly compatible with CAT-5e, however your network throughput will only be as fast as the slowest part.
Can I run CAT 5e ethernet cable outside?
CAT-5e cable is not rated for outdoor use, however it can generally be used without a problem. If possible, run the cable through some kind of conduit to prevent moisture or an attractive site for lightning to strike. You should be able to find gray PVC conduit suitable for cable at any hardware store. Remember, 100 Meters is your max distance, without some kind of hub, bridge or amplification.
What are the maximum lengths for CAT 5 cables?
For Solid UTP:
Fast Ethernet 100baseT 100 Meters (328 feet)
Twisted Pair Ethernet 10baseT 100 Meters (328 feet)

Recommended maximum lengths for Patch Cables made from stranded cable:
Fast Ethernet 100baseT 10 Meters (33 feet)
Twisted Pair Ethernet 10baseT 10 Meters (33 feet)
