CHAPTER 4: OPERATION FUNCTIONALITY
MULTILINK ML1600 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL 4–5
The use of either multi-mode or single-mode fiber to operate at 100 Mbps speed over long
distances (i.e., in excess of 400 m) can be achieved only if the following are applied:
1. The 100 Mb fiber segment must operate in full-duplex (FDX) mode (i.e. the full-
duplex (factory default).
2. The worst-case OPB of the fiber link must be greater than the fiber cable's
passive attenuation, where attenuation is the sum of cable loss, LED aging
loss, insertion loss, and safety factor.
