Technical Context

The transceiver converts electrical network data into optical signals for transmission over multimode fiber and converts received optical signals back to electrical data. Its 850 nm wavelength, 550 m reach, and DDM support provide a practical fiber uplink solution for compatible SFP network equipment.

Installation Notes

Insert the module into a compatible SFP slot and connect the duplex LC fiber pair to the optical link. Use multimode fiber and ensure that the remote transceiver or module matches the 1.25 Gbps, 850 nm, 550 m optical specification. The module is hot-pluggable and supports plug-and-play operation.
