## Long description

The Grandstream Networks F-MM850-550M-1.25G is an SFP transceiver module for fiber optic connections, supporting a maximum data rate of 1250 Mbit/s and operating at an 850 nm wavelength. This small-form-factor, hot-pluggable SFP module features a high-sensitivity PIN receiver and signal conditioning for reliable 1.25 Gigabit Ethernet links, low electromagnetic interference, ESD protection and typical power consumption of 0.8 W. It is RoHS compliant and easy to integrate into networking equipment for enterprise LANs and other optical links.
Advantages
The module provides a compact, hot-pluggable SFP form factor that simplifies installation and replacement. Low power consumption (typical 0.8 W) and RoHS compliance make it energy-efficient and environmentally compatible. Built-in high-sensitivity PIN receiver and signal conditioning improve link reliability, while low EMI and ESD protection enhance operational stability in network environments.
Suitable for
Enterprise LAN fiber uplinks
Switch-to-switch optical links
Network expansion and modular transceiver slots
Short-range multimode fiber connections (850 nm)

How to use
Insert the SFP transceiver into a compatible SFP port on a switch, router or media converter while the host device is powered according to the vendor’s guidelines for hot-pluggable modules. Connect the appropriate multimode fiber patch cable (850 nm) to the module’s optical interface. Confirm link status on the host device and verify speed and duplex settings if required. Handle the transceiver and fiber connectors by the housing; keep dust caps on unused ports and clean connectors before mating.
Usage recommendations
Use multimode fiber and patch cords rated for 850 nm operation and ensure connector types match the host equipment. Observe ESD precautions when handling the module, store unused modules in anti-static packaging, and follow the equipment manufacturer’s compatibility list to ensure optimal performance.
