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:
• Cisco SFP and SFP+ Transceiver Module Installation Notes
• Cisco 40-Gigabit QSFP+ Transceiver Modules Installation Note
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).
