Grandstream F-MM850-300M-10G Multimode-SFP/SFP+-Glasfasermodul content_copy

The Grandstream F-MM850-300M-10G is an SFP+ fibre optic transceiver module for multimode fibre, designed for use in enterprise LANs and other ultra-fast networks. It enables a data transfer rate of 10 Gbit/s and is therefore suitable for applications requiring high bandwidth and low latency. The module operates at a nominal wavelength of 850 nm and supports a maximum transmission distance of 300 metres over multimode fibre optic cable. It is designed as a hot-pluggable module, meaning it can be inserted into a compatible switch or router without interrupting network operation.

Applications
This module is typically used in enterprise networks where stable, high data rates are required over short to medium distances. It is suitable for connecting switches, servers, or other network devices within a building or between adjacent rooms. Due to its multimode technology and 850-nm wavelength, it is particularly suited for indoor environments and structured cabling systems where the maximum range of 300 metres is sufficient.

Functions and Features in Detail
The F-MM850-300M-10G features a PIN photodetector with high sensitivity, ensuring reliable signal transmission. Additionally, an signal conditioner is integrated to optimise signal quality and minimise interference. The design ensures very low electromagnetic emission (EMI) and provides excellent protection against electrostatic discharge (ESD). These characteristics increase the reliability and lifespan of the module in complex network environments.

Technology Explained Simply
The module operates in the SFP+ format, which offers a compact form factor for high-speed network connections. The term multimode means it is designed for fibre optic cables where light travels through multiple modes (paths) within the cable. This allows for higher bandwidth compared to single-mode fibres, but is limited to shorter distances. The wavelength of 850 nm is standard for multimode systems in indoor environments and offers a good balance between range and bandwidth. The maximum range of 300 metres is sufficient for many enterprise applications, especially in buildings with vertical or horizontal cabling.

Compatibility and Accessories
The module is designed for use in 10 Gigabit Ethernet applications and can be used in compatible switches, routers, or servers with SFP+ ports. It is designed as a hot-pluggable module, meaning it can be inserted without powering down the device. Its use requires a multimode fibre optic cable with a wavelength of 850 nm.

Installation and Mounting
Installation is performed by simply inserting the module into the corresponding SFP+ port of the network device. Due to its hot-pluggable feature, no network interruption is required. Correct alignment of the module is important to ensure a secure connection. Cabling is done via a multimode fibre optic cable, terminated at both ends with appropriate connectors (e.g. LC).

Operational Advantages
The module is characterised by low power consumption, which reduces operating costs and minimises heat generation within the device. The integrated ESD and EMI protection functions enhance network stability, especially in environments with high electromagnetic interference. The high data rate of 10 Gbit/s enables efficient data transfer, which is required for modern applications such as video surveillance, cloud computing, or large file transfers. The use of multimode fibre is more cost-effective than single-mode fibre, thereby reducing overall network infrastructure costs.
