1 by 8 50GHz MUX/DMUX
Family - 50GHz Channels
terra-Q 50 1 x 8
The Bookham Technology terra-Q 1 by 8 50GHz
Channel spacing Mux/Dmux module is based
on thin-film interference filter technology.
Three module design options are available.
Standard Version
This version of the product uses a simple cascade of 50GHz
filters to provide the mux or demux function. The mux and
demux are built as complementary pairs giving the lowest
overall loss.
Uniform Loss Version
This version of the product has the loss balanced between
channels to achieve lowest channel-to-channel
loss variation.
Low Chromatic Dispersion Versions
These versions offer lower values of chromatic dispersion
at the expense of higher insertion loss.
Features
ITU and Custom Wavelengths
17.4GHz standard passband
20GHz passband as
custom option
Accurate Wavelength Centering
High Channel Rejection
Excellent Temperature Stability
Compliance
