Grandstream F-MM850-550M-1.25G SFP Fiber Module – 1.25G 850nm 550m Multimode LC Transceiver

Description

The Grandstream F-MM850-550M-1.25G SFP Fiber Module is a high-performance optical transceiver designed to deliver reliable 1.25Gbps Gigabit Ethernet connectivity over multimode fiber (MMF). It is an ideal solution for enterprise networks, campus environments, and data communication systems that require stable, short-to-medium range fiber connections.

Operating at a wavelength of 850nm, this module supports transmission distances of up to 550 meters on OM2 multimode fiber and approximately 300 meters on OM1 fiber, making it perfect for in-building backbone links, server-to-switch connections, and LAN extensions.

The module features a standard LC duplex connector, ensuring compatibility with widely used fiber patch cables and network infrastructure. Its SFP (Small Form-factor Pluggable) design allows easy integration into switches, routers, and other networking devices equipped with SFP ports.

One of the key benefits of the F-MM850-550M-1.25G is its hot-swappable capability, allowing installation or replacement without shutting down network equipment. This minimizes downtime and supports continuous operation in business-critical environments.

Engineered with a high-sensitivity PIN receiver and signal conditioner, the module ensures stable signal transmission with low latency and high reliability. It also supports Digital Diagnostic Monitoring (DDM), enabling real-time tracking of performance parameters such as temperature, voltage, and optical power.

The module is compliant with industry standards such as SFP MSA, IEEE 802.3z, and SFF-8472, ensuring interoperability across multiple networking vendors.

With low power consumption (≈0.8W), excellent EMI/ESD protection, and compact design, this module is optimized for energy-efficient operation in enterprise networks.

Whether used in enterprise LANs, data centers, or fiber backbone connections, the Grandstream F-MM850-550M-1.25G SFP Fiber Module offers a cost-effective and dependable solution for high-speed optical networking over multimode fiber.
