Ruijie RG-ES100 Series Switches Hardware Installation and Reference Guide Appendix B Mini-GBIC and SPF+ Module
Category 5 (or above ) UTP or STP
For the optical module with transmission distance exceeding 40 km and more, one on-line optical attenuator should
be added on the link to avoid the overload of the optical receiver when short single-mode optical fibers are used.
Optical modules generate laser. Do not stare at light source.
To keep optical modules clean, please use dust caps when the modules are not connected with fibers.
No extra cables are needed when SFP cables are used. Inserting the two ends of a SFP cable into corresponding
ports facilitates inter-communication between the two ports.
