XGS-PON / GPON Combo OLT Transceiver – SFP-DD (Class D, I-Temp)
Product Overview
The GLOBALfiber XGS-PON / GPON Combo OLT Transceiver (Class D) is an ultra-long-reach SFP-DD optical module designed for up to 60 km PON deployments. It enables simultaneous XGS-PON and GPON operation on a single fiber, allowing operators to centralize OLT locations and extend coverage without modifying the passive network.
With very high transmit power, exceptional receiver sensitivity, and industrial temperature support, this Class D module is purpose-built for extreme distances, sparse geographies, and centralized access architectures where maximum optical margin is critical.
