Category 5e / Cat 5e (solid) structured wiring cable

Category 5e (solid) structured wiring cable (also known as Cat 5 Enhanced or Cat 5e) is designed for data transmission in computer networks running at 10 or 100 Mbps. This is a preferred choice for the 1000BASE-T/100BASE-TX specifications. 

The Category 5e range includes cables suitable for use in a variety of environments & applications. Versions with stranded conductors (called patch cables) are also available on request.
