1)
Optical switches allow an actual increase of the measurement spectrum available by factor 2 to 4.
2)
The optical switches require that the multiplexer acquires data at alternating switch positions. This reduces
the interrogator’s relative sampling rate by a factor equalling the degree of multiplexing. The sampling rate
is maximally reduced by a factor of 2 when using the 8-channel expansion and maximally by a factor of 4
when using the 16-channel expansion module.
3)
Insertion loss data apply only for one direction (monomode).
