XGSPON N2 SFP
The XGSPON N2 & GPON C+ Combo SFP+ is a dual-mode optical transceiver that supports both next-gen XGSPON and legacy GPON in a single compact SFP+ module. Designed for smooth network evolution, it enables operators to serve GPON and XGSPON users simultaneously—without hardware changes. Fully compliant with ITU-T G.984.5 (2014)/Amd.2 (10/2020) standards, this hot-pluggable module delivers high reliability, low power consumption, and excellent optical sensitivity. It integrates easily into major OLT platforms, supporting flexible deployments across a wide range of environments. With the XGSPON N2 & GPON C+ Combo SFP+, service providers can cut upgrade costs, extend infrastructure lifespan, and accelerate rollout of ultra-fast broadband—all with one simple solution.
