The WDM1r Series is a family of compact, high-performance cassette modules designed for flexible and scalable FTTx/PON network applications. Integrating multiple optical functions—such as GPON, XGS PON, NGA, 25G-PON, 50G-PON, OTDR monitoring, video overlay, and TWDM-PON—into a standardized 100×80×10 mm form factor, these modules enable efficient fiber utilization and simplified network deployment.
Compact, robust, and RoHS compliant, the WDM1r Series provides a future-ready solution for modern optical network construction and upgrade.
