1. With a 0.5 m cable, the minimum coiled diameter is negligible and the cable cannot be physically coiled
without exceeding the bending limit.

Transceiver Module Network Cables

For cabling specifications, refer to the following notes:
•
•
Each port must match the wavelength specifications on the other end of the cable, and the cable must not
exceed the stipulated cable length. Copper 1000BASE-T SFP module transceivers use standard four twisted-pair,
Category 5 cable at lengths up to 328 feet (100 meters).
