Description

Black Box EYNLSF643AW-PB-1000 CAT6 Shielded Ethernet Bulk Cable

Overview

The Black Box EYNLSF643AW-PB-1000 is a 1000-foot spool of Category 6 bulk Ethernet cable designed for reliable data transmission in demanding environments. Featuring a shielded foil twisted pair (f/utp) construction and a Low Smoke Zero Halogen (LSZH) jacket, this cable minimizes electromagnetic interference (EMI) and reduces toxic emissions in case of fire. Its 400 MHz bandwidth supports Gigabit Ethernet speeds, making it suitable for high-performance network backbones, IP surveillance systems, and data center applications where signal integrity is critical.

Compatibility

This CAT6 cable is compatible with all standard RJ45 connectors and network devices supporting Gigabit Ethernet (1000BASE-T) and lower speeds (100BASE-TX, 10BASE-T). It is suitable for use with network switches, routers, IP cameras, access control panels, and other network-enabled equipment from any manufacturer that adheres to Ethernet standards. The LSZH jacket is specifically recommended for installations within plenum spaces or public buildings where fire safety regulations mandate low-smoke and non-toxic cable jacketing.

Installation Notes

The cable requires standard termination tools for RJ45 connectors. Due to its shielded construction, proper grounding of the cable shield at both ends is essential to achieve optimal EMI rejection and prevent ground loops. Ensure connectors are securely crimped to maintain continuity of the shield. The LSZH jacket is less flexible than standard PVC, so plan for slightly larger bend radii during installation to avoid kinking the cable. The 1000-foot length is supplied on a reel for easier deployment.
