Description:
The TQB-QSFP+-40G-LR4 also called QSFP or QSFP 40G or QSFP Transceiver or Fiber Optic Transceiver Module, which is a transceiver module designed for 10km optical communication applications. It is fully compliant with the QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4 and OTU3 C4S1-2D1 standard. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDM optical signals and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gb/s input into 4 CWDM channel signals and converts them to 4 channel output electrical data.
Features:
4 CWDM lanes MUX/DEMUX design.
Up to 11.2Gbps per channel bandwidth.
Aggregate bandwidth of > 40Gbps.
Duplex LC connector.
Compliant with 40G Ethernet IEEE802.3ba and 40GBASE-LR4 Standard.
