DTG-1031 Series
Duplex-SC Single-Mode Transceiver For GPON-ONU
2.5Gbps Downstream / 1.25Gbps Upstream
EMPOWERING THE ITU-T G.984 GPON!
The ITU-T G.984 GPON networks, is an unprecedented optical access solution to deliver extremely high bit rates and multiple services provisioning capability for FTTH/B/C (fiber-to-the home/building/curb) networks.
To support the GPON movement, DenseLight's is offering the DTG-1031, which is a duplex-SC Single Mode Transceiver fully compliant with the ITU-T G.984 GPON standards up to 10km.
Designed to operate in the ONU (optical network unit) side of GPON networks, the DTG-1031 includes a 1310nm 1.25Gbps burst mode transmitter and a 2.5Gbps continuous-mode receiver.
