The Ubiquiti UISP Fiber Coexistence WDM Filter (Model: UACC-UF-WDM-XGS) is a high-performance wavelength division multiplexing (WDM) module designed to combine XGS/XG-PON and GPON services seamlessly over a single fiber distribution system. This device enables efficient coexistence of multiple Passive Optical Network (PON) types, optimizing fiber infrastructure usage and network scalability.

Encased in a durable metal chassis, the filter fits into a 1U rack-mount form factor, measuring 442 x 120 x 43.7 mm and weighing approximately 1.8 kg. It features 24 SC/UPC connectors divided evenly among COM, GPON, and XGS/XG-PON ports to facilitate versatile network configurations.

Optical performance is top-tier, ensuring minimal signal degradation with a maximum insertion loss of 1 dB and a minimum isolation of 25 dB. The return loss is rated at a minimum of 50 dB and polarization-dependent loss (PDL) does not exceed 0.1 dB. The filter supports ITU-T G.657.A1 single-mode fiber to guarantee compatibility with modern optical networks.

Ideal for enterprise, ISP, and service provider environments, this filter supports robust and efficient fiber network deployments by allowing various PON technologies to coexist on a shared fiber backbone. The product complies with NDAA standards, underscoring its trusted quality and security.
