C-Band/L-Band Single Mode Filter WDM
The C-Band/L-Band Single Mode Filter WDM is a thin film filter-based wavelength division multiplexer designed to combine or separate C-band and L-band optical signals in single mode fiber systems. It supports C-band wavelengths from 1500–1562nm and L-band wavelengths from 1570–1610nm, with selectable pass and reflect channel configurations. This device provides low insertion loss, high channel isolation, low polarization dependent loss, and stable optical performance in a compact Φ5.5 × L35mm package. It is suitable for DWDM transmission systems, C+L band optical networks, optical amplifiers, fiber monitoring, fiber sensing, and test applications requiring reliable C/L band wavelength management.
