Description
The FTCQ-4X-LR4xx is a 4x10G hot pluggable optical transceiver. The F-tone Networks technology enables the integration of 4 transmitters, 4 receivers and an optical MUX/DeMUX with AAWG into a small form factor package that delivers a 40 Gbps data link in a compact QSFP footprint. The optical connectivity is based on two SMF LC connectors, one for Tx and one for Rx. The Tx and Rx each consist of 4 10Gb/s CWDM channels, whose wavelengths are in the 1300nm range. The QSFP-LR transceiver is designed for applications based on the QSFP MSA, IEEE 802.3ba, and 40GBASE-LR4 requirements of up to 10km reach.
Features
● Transmission data rate up to 11.2Gbps per channel
● QSFP+ MSA compliant
● Compliant to IEEE 802.3ba specification for 40GBASE-LR4 links
● 4 CWDM un-cooled DFB lasers, using ITU G.694.2 wavelength grid at 1271, 1291, 1311, and 1331 nm , with AAWG.
● High Sensitivity PIN-TIA with AAWG DEMUX.
● Up to 10km reach over standard single mode fiber
● Compliant with QDR/DDR Infiniband data rates
● Hot pluggable electrical interface
● Power consumption＜2.5W
● 3.3V power supply
● RoHS 6 compliant（lead free）
● Case operating temperature
Commercial: 0 ~ +70℃
Industrial: -40 ~ +85℃
Applications
● 40G Ethernet
● Infiniband QDR and DDR interconnects
● Client-side 40G Telecom connections
