SFP TRANSCEIVER 1.25GB 850NM

The Black Box SFP Transceiver 1.25GB 850NM is a network transceiver for IT teams and network administrators who need an SFP option for equipment that matches its listed specifications.

Recommended For

• Network installers adding a 1.25-Gbps fiber link between SFP-equipped switches or other network devices over multimode fiber, for links up to 550 m.
• IT teams connecting equipment in the same building or campus where the existing fiber plant is multimode, 850 nm, and uses LC duplex connectors.
• Users adding a compatible SFP to Black Box KVM-over-IP or extender equipment when the system documentation specifies the LFP441 or an equivalent 850-nm multimode module.
• Technicians replacing or matching a 1.25-Gbps, 850-nm multimode SFP in an existing fiber link, after confirming that the host device accepts the module.

Real-World Use Scenarios

• Link two switches in separate rooms or wiring closets over existing multimode fiber; on a compatible 1000BASE-SX setup, the connection can span up to 550 m with the specified fiber.
• Add a fiber uplink from a compatible switch to a router or server with an SFP port; it provides a 1-Gigabit Ethernet link when the device, optic, and multimode-fiber connection are compatible.
• Replace a failed 850-nm 1000BASE-SX optic in an existing fiber link; the connection can be restored if the host equipment supports the module and the fiber and LC connections match.
• Connect compatible legacy Fiber Channel equipment over multimode fiber; Black Box lists this module for dual-speed 1.063/2.125-Gb/s Fiber Channel, so both endpoints must support the intended link speed and optic.
