Sustain high-speed switch-to-switch connectivity across short-reach multimode fiber with a QSFP28 transceiver designed for 100 GbE environments. The AddOn Networks E100GQSFP28SRX-C-AO uses an MPO connector and 850 nm optics to support data center links that demand tight latency control and clean cable management. This module fits deployment patterns where 100 GbE density matters more than long-haul reach. It is well suited for leaf-spine fabrics, top-of-rack uplinks, and aggregation layers that need consistent short-distance performance without moving to more expensive long-reach optics. The QSFP28 form factor helps preserve front-panel space while supporting modern high-bandwidth switching architectures. For teams standardizing on multimode infrastructure, this transceiver offers a practical path to higher throughput without changing the fiber plant. It is a focused choice for environments that value predictable short-reach optics, compact packaging, and straightforward integration into enterprise switching platforms.
