UACC-OM-QSFP28-LR4 - Ubiquiti 100G LR4 Single-Mode Optical Module

The Ubiquiti 100G LR4 Single-Mode Optical Module (UACC-OM-QSFP28-LR4) is a high-performance QSFP28 transceiver designed to deliver 100 Gbps connectivity over distances of up to 10 km using single-mode fibre. With its duplex LC UPC connector, this optical module is engineered for demanding network environments requiring reliable, high-speed uplinks and long-distance fibre connections.

Built for enterprise-grade performance, the UACC-OM-QSFP28-LR4 supports maximum data rates of 100 Gbps and is compatible with both QSFP28 and QSFP+ interfaces. Operating across multiple wavelengths (1295 / 1300 / 1304 / 1309 nm for both TX and RX), this module delivers exceptional transmission quality for backbone connectivity, aggregation networks, and high-capacity data centre deployments. With a power consumption of just 4 W and an ambient operating temperature range of 0 to 70° C, this transceiver is optimised for continuous, efficient operation in rack-mounted environments.
