Mini Size PM CWDM (Coarse WDM)
Miniature Polarization-Maintaining Coarse Wavelength Division Multiplexer (PM CWDM) covering 20 nm channel grid from 1260 nm to 1620 nm. Features low insertion loss (<=0.6 dB pass channel), wide passband (>=±6.5 nm), high adjacent channel isolation (>=30 dB), and high directivity in a dia. 3.2 x 30 mm package.
Technical Specifications
With connectors, IL increases by 0.3 dB, RL decreases by 5 dB and ER decreases by 2 dB. Custom CWDM wavelength bands, connector terminations, and fiber types are confirmed upon engineering review.
Configuration and ordering notes
Configuration parameters include the required ITU CWDM channel (from 1271 nm to 1611 nm at 20 nm increments). Engineering review covers whether sub-band reflection (1260-1460 nm or 1460-1620 nm) or full-band reflection is needed for the wavelength-routing layout.
Key Applications
Metro and access CWDM systems; 4G/5G fronthaul transceivers; Fiber sensing multiplexers; Compact multi-wavelength laser combiners.
