100G BIDI SR1.2 QSFP28 Optical Transceiver Duplex LC

The FIBERSTAMP 100G BIDI SR QSFP28 optical transceiver is designed for using in 100-Gigabit Ethernet links up to 70m using OM3 and 100m using OM4. It is compliant with the QSFP28 MSA, IEEE802.3cm-2020 and CAUI-4(no FEC)¹. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP28 MSA.

The module incorporates 2 channels 850nm/910nm VCSEL and PIN photo detector, transmitting and receiving each optically over one simplex LC fiber using bi-directional optics. This results in an aggregate bandwidth of 100Gbps into a duplex LC cable. This module can convert 4 channels of 25Gbps (NRZ) electrical input data to 2 channels of 50Gbps (PAM4) optical signal, and also can convert 2 channels of 50Gbps (PAM4) optical signal to 4 channels of 25Gbps (NRZ) electrical output data. The electrical interface uses a 38-contact edge type connector. This transceiver is a high performance module for short-range duplex data communication and interconnects applications.
