QFPQL040410D is a high performance QSFP+ transceiver module for 40 Gigabit Ethernet and OTN OTU3 data links over a single mode fibre pair. The maximum reach is 40km. The four transmitters are CWDM DFB lasers generating four optical 10Gbps output signals, which are multiplexed together at the optical output port. The four receivers are PIN photodiodes which detect (after optical de-multiplexing) 4´ 10Gbps optical input signals.
