Product Details

D-NET's 100G QSFP28 LR4 optical transceiver converts four input channels (ch) of electrical data, each operating at 25.78 Gbps to 27.95 Gbps, into four optical signals, and then multiplexes them into a single channel for 100Gb/s optical transmission. Conversely, on the receiver side, the module optically demultiplexes a 100Gb/s input into four signals, each corresponding to one of the four lanes, and converts them back into four lanes of output electrical data. The central wavelengths for these four lanes are 1296 nm, 1300 nm, 1305 nm, and 1309 nm, respectively.

FAQ

1. What is QSFP28 LR4?
The 100G QSFP28 LR4 optical transceiver converts 4 inputs channels (ch) of 25.78 Gbps to 27.95Gbps electrical data to 4 lanes optical signals, and multiplexes them into a single channel for 100Gb/s optical transmission.

2. What is the difference between SR4 and 100G LR4?
With 100GASE-LR4, each single strand of fiber carries four signals slightly offset from the 1310nm wavelength to avoid interference (SR4 uses 850nm.)

3. How much power does a 100G LR4 consume?
D-NET QSFP28–100G-LR4 is compliant to 100GbASE-LR4 of the IEEE 802.3-2012 Clause 88 standard IEEE 802.3bm CAUI-4 chip to module electrical standard ITU-T G.959.1-2012-02 standard , the maximum power consumption of QSFP28–100G-LR4 is 5 W and its power supply voltage is +4 V.
