Typical distances listed are based on the follow-
ing assumptions for system loss. As actual losses
vary from one installation to another, the distance
covered by your system may vary.
CONNECTOR LOSSES (TOTAL OF BOTH ENDS)
ST connector 2 dB
FIBER LOSSES
820 nm multimode 3 dB/km
1300 nm multimode 1 dB/km
1300 nm single mode 0.35 dB/km
