The Finisar FTLQ7181MALL is a used CFP transceiver offering 40G data rates over single-mode fibre using CWDM 1310nm technology. It features a 4×10G CWDM DFB transmitter and 4×10G PIN receiver configuration supporting both Ethernet and OTN applications.

Typically includes:
• Finisar FTLQ7181MALL CFP transceiver module

The Finisar FTLQ7181MALL is a CFP (C Form-factor Pluggable) optical transceiver designed for 40 Gigabit Ethernet and Optical Transport Network applications. It complies with the IEEE 802.3ba 40GBASE-LR4 standard and supports OTN OTU3 operation, making it suitable for both data centre interconnects and carrier-grade transport networks.

The module uses a 4×10G CWDM (Coarse Wavelength Division Multiplexing) DFB (Distributed Feedback) laser transmitter array and a 4×10G PIN photodetector receiver array. The four CWDM lanes are multiplexed onto a single-mode fibre pair via an integrated MUX/DEMUX, enabling transmission over distances of up to 10km.
