AddOn F5-UPG-QSFP28-LR4-AO 100GBASE-LR4 QSFP28 Transceiver

Extend a 100 GbE Ethernet connection beyond the short-reach limits of multimode optics with a QSFP28 LR4 module built for duplex single-mode fiber. LR4 carries four optical lanes over a two-fiber LC connection, allowing a single transceiver at each end of the link to support long campus, data center, or building-to-building runs. The QSFP28 form factor fits 100 GbE interfaces that accept this optical module type. F5-UPG-QSFP28-LR4-AO is an AddOn replacement optic compatible with F5 Networks equipment using the corresponding QSFP28 LR4 interface. Its 100GBASE-LR4 operation supports link distances up to 10 km over single-mode fiber, making it suited to aggregation paths, core interconnects, and remote equipment rooms where copper and short-range optics cannot span the required distance. The duplex LC interface reduces fiber count compared with parallel-fiber 100 GbE connections. TAA compliance distinguishes this module for deployments that require products meeting Trade Agreements Act sourcing requirements. Select it when both ends of the path need 100GBASE-LR4 QSFP28 optics, the installed cabling is duplex single-mode fiber, and the link budget falls within the 10 km LR4 reach. It is a long-reach optical interface rather than a DAC cable or short-range multimode transceiver.
