BN-CKM-S-SX BladeNetworks Compatible SFP SX 550m MMF Transceiver

The BN-CKM-S-SX is a 1G SX SFP that runs gigabit Ethernet up to 550m over multimode fiber through a duplex LC pair. That reach covers the short-haul optical role inside a building or across a campus riser where multimode is already pulled. It comes coded to register on BladeNetworks hosts as a genuine SFP and seats hot with no configuration step, reporting DDM diagnostics across the 550m link.
