Maintain high-speed optical links across short-reach multimode fiber runs with this AddOn IBM BN-CKM-SP-SR compatible SFP+ transceiver. Designed for 10GBASE-SR connectivity, it supports 10 Gigabit Ethernet over MMF up to 300 m at 850 nm, giving infrastructure teams the reach they need for access-layer switches, aggregation uplinks, and dense rack-to-rack interconnects. The LC connector and hot-swappable form factor simplify deployment and replacement during maintenance windows. That matters when uptime is measured in minutes, not hours. TAA compliance also makes this module a practical fit for public sector and regulated procurement workflows where sourcing requirements are part of the decision. Compatibility with IBM Blade Network Technologies and Blade RackSwitch platforms helps reduce qualification risk while preserving the economics of third-party optics. For teams standardizing on proven 10 GbE infrastructure, this module offers a precise fit: the right reach, the right interface, and the operational flexibility to keep ports active without overbuying capacity.
