10.4.2.1. Single Mode Optical Splitter/Coupler (98-100001)
Single Mode Optical Splitter/Couplers are used whenever it is necessary to split or combine outputs
from optical transmitters or inputs to receivers. Operators should be aware that a small insertion loss
(typically 3-4dB) is common with these type of couplers.
Single Mode Optical Splitter/Coupler (98-100001) It is an O.E.M unit featuring almost negligible
insertion loss to the F/O signal. Extreme caution should be exercised when handling these devices.
Special attention should be shown to the connectors; repair of a broken Splitter/Coupler is not
possible; replacement is the only option.
In the Fibre Optic Splitter (55-165507) in University Station Master Site 1 (80-330552-1), Single Mode
Optical Splitter/Coupler (98-100001) is used to split the optical signal from the FO TX module in F/O
Link Subsystem (98-700001) into two equal paths.
