CAT5 and CAT6 are typically installed as four-pair; it's difficult to find cable containing more than the typical four-pair (8P8C) connections.
Previously, someone wrote that "CAT5 and CAT6 are defined as four pair." The reality is a bit more subtle -- there are separate performance (X amount of crosstalk/loss at a frequency of Y MHz) and cabling specs (Q pins, with pairs ordered as 1-2, 3-6, 4-5, 7-8, cable colors pink, green, blue with polka dots, etc.).
I have found 25 pair CAT5 cable. Cables on Demand, for example, carries this under part number MP-5T90FFUNNA. It terminates in giant RJ-21 connectors on each end. They also make breakout cables to connect to standard RJ-45 ports.
Expect to pay through the nose for this, though. It looks like it runs 85 cents/foot in 100 foot lengths, vs. 5-6 cents/foot for standard CAT5 in 1000 foot spools.
What else can I help you with?
Two types of cable in computers?
There is the USB cable and the twisted pair cable (Cat 5 and Cat 6) for networking.
What is a Cat 5?
It's short for "category five", which is a type of cabling. The "Cat 5" part refers to the technical specifications of the cable, such as the bandwidth. Cat 5 cable is (usually) unshielded twisted-pair.
What is the most popular media option for the Ethernet networks?
CAT 5 Cable and RJ 45 Cable (Twisted-pair Ethernet). Unshielded twisted-pair (UTP) cable
What is a cat 5 cable and why is it used?
Cat-5 cable, sometimes called Ethernet cable, is short for Category 5 cable, a current industry standard for network and telephone wiring. Cat-5 cable is unshielded wire containing four pairs of 24-gauge twisted copper pairs, terminating in an RJ-45 jack. If a wire is certified as Cat-5 and not just a twisted pair wire, it will have "Cat-5" printed on the shielding.
What does the twisting of the wires achieve in a CAT-5 cable?
It reduces the opportunity for the signals on one pair to be transferred accidentally to a different pair.
How may pair used in cat 5 cable?
4 pairs of wires, or 8 wires total
What Ethernet standard will supply power?
Any that use a Cat 5 or better twisted pair cable
How do the characteristics of coaxial cable compare with twisted-pair cable?
Both the coaxial cable and twisted pair cable have a basic connection medium for network cabling. <<>> Coaxial cable can be used for transmission of RF (radio frequencies) whereas Cat 5 (twisted pairs cable) can not.
RJ-45 connectores are used with?
Ethernet cable being shielded or unshielded twisted pair or CAT 5.
What are the two most commonly used media types in Ethernet networks today?
1. Copper UTP (Unshielded Twisted Pair) 2. Optical Fiber
How many no of twist per feet in cat 6 cable?
Cable twisting length is not standardized. In a typical cable there are 1.5 to 2 twists per cm in Cat-5(e) and 2 or more twists per cm in Cat-6. One cm equals 0.393701 inches. Within a single cable, each coloured pair have different twist lengths. Each cable manufacturer's twists per pair is usually different from another manufacturer.
How many wires does a CAT-5 cable have a CAT-53 and a coaxial cable?
Cat-5 has 4 pairs and 8 wires
