Note
Typical link distance is based upon the following assumptions for system loss. As actual
losses vary between installations, the distance covered will vary.
Connector loss: ...............................................2 dB

Splice loss: ........................................................One splice every 2 km at 0.05 dB loss/splice
System margin: ..............................................3 dB additional loss added to calculations to compensate
for all other losses
