C-Band Red/Blue Single Mode Filter WDM
The C-Band Red/Blue Single Mode Filter WDM is a thin film filter-based wavelength division multiplexer designed to separate or combine red and blue wavelength bands within the C-band optical spectrum. It supports two channel configurations, with the blue band covering 1547–1561nm and the red band covering 1530–1543.2nm. 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, EDFA links, C-band optical monitoring, fiber sensing, and test applications requiring reliable red/blue band splitting or combining over single mode fiber.
