Summary

Recommendation ITU-T L.109.1 explains the type II optical/electrical hybrid cable (OEHC) in which a copper pair is used for power delivery (not for telecommunications) and an optical fibre can support data transmission up to and beyond 1 Gbit/s. The current application scenarios for remote powering and data transmission of access points and other equipment require a type of hybrid cable that has a small footprint, is lightweight, and is convenient for installation.
