The QSFP28-100G-BX20-U/D is a transceiver module designed for 20km optical communication applications. The design 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 module 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. Reversely, on the receiver side, the module optically de-multiplexes a 100Gb/s input into 4 lanes signals, and converts them to 4 lanes output electrical data.
The central wavelengths of the optical are 1291 nm/1311 nm . It contains a Bidirectional LC connector for the optical interface and a 38-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module.
Product Features:
- 4 lanes MUX/DEMUX design
- Integrated CWDM TOSA / ROSA for up to 20 km reach over SMF
- Support 100GBASE-CWDM4 for line rate of 103.125Gbps and OTU4 for line rate of 111.81Gbps
- Aggregate bandwidth of > 100Gbps
- Duplex LC connectors
- Compliant with 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 ·
- Single +3.3V power supply operating
