3.2 Splitter Losses
Description
Splitters have the insertion losses marked on packaging or in
accompanying documentation.
•
A 50:50 splitter will have an insertion loss of between 3 dB and 4
dB on each output
•
90:10 splitter will have losses of about 10 dB in the high loss output,
and <2 dB in the low loss output
The 1000baseSX transceiver uses 850nm optics. Splitters used must be
designed for 850nm as the insertion loss will vary for different
wavelengths.
Single mode
fibre loss
A single mode fibre connected to a multi-mode input has minimal extra
loss.
Multi-mode
fibre loss
A multi-mode fibre connected to a single mode input creates large and
unpredictable loss.
