Optoplex optical interleaver based technology can provide customized flat top comb filter. With conventional Fabry - Perot cavity different comb filter comb filter bandwidth can be made into Optoplex from several GHz to a very wide, it is possible to transmit modulation future DWDM systems signal. FSR and the pass band width of the filter can be customized.
Optoplex based micro-optical and phase modulation by film coating patented technology, is a flat-topped comb filter with a low temperature sensitivity, wide and flat with a channel, high channel isolation, low polarization dependent loss and insertion loss of uniformity and other characteristics of a purely passive devices. The product complies with Telcordia GR-1221 standard. -
Features and advantages of the flat top optical comb filter● wide and flat with a channel● low polarization dependent loss● Non-thermal design● low and customizable dispersive spectral shape● low insertion loss● single device can cover the entire C- and L- band● Telcordia GR-1221/63 standard
-
Applications flattened optical comb filter● DWDM system noise suppression● high bandwidth signal modulation rate cuts● Adjust the signal spectrum shape● DWDM system frequency calibrator
