In each CWDM channel (in O-band or E- Band), there are 16 sub-DWDM channels at the low-wavelength (Low-Band) side, or the high-wavelength (High- Band) side of each CWDM channel (1271, 1291, 1311, 1331, 1351, 1411, 1431, 1451 and 1471), respectively.
Each CWDM channel has a +/-7.5nm channel width, while the High-Band is defined as the CWDM channel + 7.5nm while the low-band is defined as CWDM channel – 7.5nm. Within the High- or the Low-Band, there are total 16 DWDM channels, respectively, with a channel spacing of about 0.37nm. The MUX (or DeMUX) is based on optical interleaver and DWDM thin film filters. This configuration has wide operating temperature range (-40C to +85C) and superior performance, such as wide passband width, low insertion loss, high isolation, and excellent thermal stability, etc., over AWG technology.Features
