The multi/demultiplexers use filtering, polarizing and phase retarding means to combine and split 4 optical channels, spectrally close to each other (821, 827, 833, 839 nm) with an high isolation ratio. The spectral isolator using similar means shows 3 paths : transmitting, communication and stracking. In nominal mode it transmits the MUX channels, receives the 870 nm communication channel and divides it into a given apportionment ratio to provide the tracking function. In calibration mode it… Expand
