Flat-Top Comb Filters

Optoplex provides costomized flat-top optical comb filter based on its optical interleaver technology. In contrast with traditional Fabry-Perot cavity-based comb filter, Optoplex's comb filter is capable of transmitting modulated DWDM signals with its passband width available anywhere down to a few GHz. Both the filter channel spacing (FSR) and filter duty cycle (3-dB bandwidth to FSR ratio) can be specified by customers.
