40Gbps QSFP+ LR4 10km Optical Transceiver,This product is a 40G QSFP+ LR4 integrates four transmitters and receivers into one module. The central wavelengths of the channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G.694.2.
40Gbps QSFP+ LR4 10km Optical Transceiver
In the transmitter side, the four lanes of optical data channels are optically multiplexed by the integrated optical multiplexer. In the receive side, the four lanes of optical data channels are optically de-multiplexed by the integrated optical de-multiplexer. Each data channels is recovered by a PIN photo-detector and trans-impedance amplifier, retimed.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ IEEE802.3ba 40GBASE-LR4 and compliant to SFF-8436.

Notes:
1. GND is the symbol for signal and supply (power) common for QSFP+ modules. All are common within the QSFP+ module and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the host board signal common ground plane.
2. VccRx, Vcc1 and VccTx are the receiver and transmitter power suppliers and shall be applied concurrently. Recommended host board power supply filtering is shown in Figure 4 below. Vcc Rx, Vcc1 and Vcc Tx may be internally connected within the QSFP+ transceiver module in any combination. The connector pins are each rated for a maximum current of 1000mA.
