Manufacturer's description and specifications:

Cisco Compatible 100GBASE-SR Bi-Directional QSFP28 Optical Transceiver Module for Ethernet and Data Center (MMF, 850nm, 880nm, 910nm and 940nm, 100m, LC, DOM)

The Cisco Compatible 100GBASE-SR Bi-Directional QSFP28 transceiver is a pluggable optical transceiver with a duplex LC connector interface for short-reach data communication and interconnect applications using Multi-Mode Fiber (MMF). It offers customers a compelling solution that enables reuse of their existing 10 Gb duplex MMF infrastructure for migration to 100 Gigabit Ethernet connectivity.

This transceiver is compliant with the QSFP28 MSA and IEEE 802.3bm CAUI-4 electrical interface. Digital diagnostics functions are also available via an I2C interface, as specified by the QSFP28 MSA, to allow access to real-time operating parameters.
