The MN9610B/9611B has excellent attenuation accuracy in the range
of 0 to 60 dB. It uses attenuation elements with flat wavelength characteristics
to achieve low polarization dependent loss (PDL) and high
return loss. A user replaceable adapter option is also available when
the fiber end face is burned as a result of inputting high output light
levels when the connector is dirty.
