Cat5e UTP Bulk Lan Cable & Cat5e UTP Patch Lan Cable

 

Category 5 Cable (Cat 5) is a twisted pair cable for carrying signals. This type of cable is used in structured cabling for computer networks such as Ethernet. It is also used to carry other signals such as telephony and video. The cable is commonly connected using punch down blocks and modular connectors. Most Category 5 cables are unshielded, relying on the twisted pair design and differential signaling for noise rejection. Category 5 has been superseded by the Category 5e (enhanced) specification.

Cable Standard

 

Bending radius

Most Category 5 cables can be bent at any radius exceeding approximately four times the diameter of the cable.

 

Maximum cable segment length

According to the ANSI/TIA/EIA standard for category 5e copper cable (TIA/EIA 568-5-A), the maximum length for a cable segment is 100 meters (328 feet).

 

Conductor required

10BASE-T and 100BASE-TX Ethernet connections require two cable pairs. 1000BASE-T Ethernet connections require four cable pairs. Cat5 and Cat5e cables typically use 24-26 AWG wire.
