Outline of Product
Q8172 optical channel selector is the 2 x 5 optical switch for the single
mode (SM10/125 urn) fiber of 1.3
urn
and 1.55
urn
bands. The switch can be
changed over by operating the front panel keys or by changing over the
optical path from channel
1
to channel 5 for COMMON A or COMMON B using,
the GPIB command.
Generally, since Q8172 is equipped with GPIB, it can be operated
externally by only connecting to the controller.
1.2 Inspection
When Q8172 is delivered to you, check that no breakage occurred during
transportation.
