Dell 407-BCHI-RFB is a refurbished optical transceiver for short-distance fibre network links. It provides 25 Gigabit Ethernet connectivity in the SFP28 form factor, for network equipment with a compatible SFP28 port.
The short-range optic operates at an 850 nm wavelength. This makes the module suited to fibre connections where an SR transceiver is required. Its compact pluggable format provides a way to add an optical network link to compatible equipment. The listed item is refurbished.
