The Cisco Compatible 100GBASE-SR1.2 BiDi QSFP28 transceiver is a pluggable optical module with a duplex LC connector, designed for short-reach data communication and interconnect applications over Multi-Mode Fiber (MMF). Supporting 100Gb/s data rates, it integrates four electrical data channels into two optical lanes using Dual Wavelength VCSEL (850nm and 910nm) for optical communication. It offers customers a compelling solution that enables reuse of their existing 10/40Gb duplex MMF infrastructure for migration to 100G with a path to 400G.
