UFiber Series · NDAA COMPLIANT
Seamless XGS-PON & GPON Fiber Coexistence Solutions
The Ubiquiti UACC-UF-WDM-XGS is an NDAA compliant, passive optical WDM (Wavelength Division Multiplexing) filter designed to enable simultaneous transmission of GPON and 10G XGS-PON services over a single shared Fiber-to-the-Home (FTTH) distribution network. By multiplexing distinct upstream and downstream optical wavelengths onto a single fiber strand, operators can upgrade existing legacy GPON infrastructure to high-speed symmetrical 10G XGS-PON services without replacing deployed fiber cables or interrupting active subscribers.

Cost-Effective Network Migration Without Fiber Overhaul
Engineered with high isolation and minimal insertion loss, the UACC-UF-WDM-XGS allows service providers to combine GPON OLT wavelengths (1490nm TX / 1310nm RX) and XGS-PON OLT wavelengths (1577nm TX / 1270nm RX) smoothly onto a common feeder fiber. Because the device is 100% passive, it requires no electrical power, ensuring maximum uptime, maintenance-free operation, and effortless deployment in indoor or outdoor optical distribution enclosures.
Zero-Downtime Migration
Overlay next-generation 10 Gbps XGS-PON capacity directly over active GPON subscriber lines without taking current users offline or altering passive splitters.
High Channel Isolation
Precision thin-film filter technology blocks cross-talk between overlapping GPON and XGS-PON optical bands to ensure high link stability and low error rates.

Is the Ubiquiti UACC-UF-WDM-XGS NDAA compliant?
Yes, the UACC-UF-WDM-XGS optical filter is officially NDAA compliant, rendering it approved for government, defense, and regulated ISP infrastructure deployments.
Why do I need a WDM coexistence filter?
A coexistence WDM filter allows GPON (2.5G/1.25G) and XGS-PON (10G/10G) equipment to share the exact same physical fiber strand without interference by combining their separate optical wavelengths.
Does this device require external power?
No. The UACC-UF-WDM-XGS is a purely passive optical component and requires no electrical power supply or battery backup.
Does this filter add significant optical signal loss?
The unit is designed with minimal insertion loss (typically <1.0 dB to 1.5 dB), ensuring your optical power budget remains within safe operational limits for extended distance links.
