Description

Bidirectional QSFP28 that delivers 100GbE over existing duplex multimode fiber with standard LC connectors—no MPO trunk required. Uses dual-wavelength transmission to achieve short-reach 100G over OM3/OM4 plants, ideal for top-of-rack to aggregation upgrades reusing duplex MMF. Provides DOM and low-power operation for dense data center deployments.
