Build longer 100 GbE links without changing the network architecture around shorter-reach optics. This AddOn Networks compatible Fujitsu module uses a QSFP28 form factor, LC duplex connectivity, and 1,309 nm optics to support up to 40 km over single-mode fiber. It is a strong fit for metro aggregation, campus interconnects, and data center-to-data center transport where distance is part of the design requirement. For infrastructure teams, the value is not just reach. It is the ability to standardize on a compact, high-density transceiver while preserving the optical budget needed for extended runs. That matters when you are extending production traffic between facilities, consolidating switching layers, or replacing mixed-vendor optics with a more controlled sourcing model. This module is built for environments that need long-distance 100 GbE transport with predictable fit and straightforward deployment. The LC interface keeps fiber handling familiar, while the QSFP28 footprint preserves switch density. For teams balancing performance, distance, and procurement discipline, it delivers the right profile for serious network builds.
