Deliver 100 GbE connectivity where short-reach optics make the most sense. This AddOn Finisar FTLC9558REPM-compatible QSFP28 transceiver is built for 100GBASE-SR multimode deployments, giving infrastructure teams a dense, practical option for high-speed links inside the data center. Its short-reach design is well suited to leaf-spine fabrics, top-of-rack to aggregation paths, and other in-building connections where multimode fiber keeps cabling straightforward and cost controlled. The QSFP28 footprint preserves port density, while TAA compliance supports procurement workflows that require sourced hardware to meet specific purchasing standards. For teams standardizing on 100 GbE, this module offers a clear fit when the goal is to move traffic efficiently across short distances without paying for long-reach optics that are not needed. AddOn compatibility also gives buyers a credible alternative to OEM-branded transceivers, helping align platform requirements with budget discipline in enterprise environments.
