CTOS Shunt caps
This device is designed to test the electronic emitter and receiver as well as the optical receptacle and the link before the optical link deployment in the field. The loop back is done by channel pairs: channel 1 with channel 2, channel 3 with channel 4.
CTOS receptacle protective shunt cap (BPPSA/BPESA)
The receptacle protective shunt cap is used to test the emitter, the receiver and the CTOS receptacle on a vehicle before using the link. This shunt cap introduces a large insertion loss which is optical power budget dependent and has to be defined with the customer (generally 20 dB max). The BPESA is dedicated to test the jam nut receptacle. It is delivered with a rope and a ring to be fixed under the hexagonal nut in order to replace the receptacle protective cap (see the drawing). The BPPSA is dedicated to test square flange receptacle. It is delivered with a panel attachement cord and can replace the receptacle protective cap. The BPBSA itself is equipped with a protective cap.

CTOS BSA
The BSA is a plug shunt cap with a low insertion loss, to test the plug to plug CTOSCTOL patchcord on a reel before the optical link is deployed.
The maximum insertion loss is fixed at 5 dB. The BSA is equipped with a protective cap.
