6.4.3.1. 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 BEACON HILL STATION MASTER SITE 1 (80-330551-1),
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.
6.3.5. Optical AB Switch FC/APC (98-700002)
Optical A/B Switch FC/APC (98-700002) an O.E.M. sourced Fibre Optic relay supplied as a 1U rack
mount tray. 98-700002 allows for the automatic switching between two optical inputs to provide a
common optical output. Manual selection of the input is also possible via toggle switches on the front
panel.
