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.
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.
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.
