Product Description
The NEW GPFD with 9dB SFP C++++ GPON OLT Module is a high-power, long-reach optical transceiver designed for GPON OLT slots, specifically for GPFD boards in fiber access networks. Offering a 9dB optical power budget and conforming to Class C++++, this SFP module supports stable transmission for up to 128 ONTs over 20 km of single-mode fiber.
Fully compliant with ITU-T G.984.2 and G.984.5, this transceiver operates at 2.488 Gbps downstream and 1.244 Gbps upstream using SC/UPC optical interfaces. It is hot-pluggable and supports real-time digital diagnostics (DDM/DOM), making it a reliable solution for high-density GPON deployments.
