Modulo SFP ALLNET ALL4790-INDU 2.5G multimodale LC industriale -40 a +85°C

The ALLNET ALL4790-INDU 2.5G Multimode LC industrial SFP module is a compact fiber transceiver designed for use in industrial and harsh-environment networks. It supports data rates up to 2.5 Gbit/s over multimode fiber and uses an LC duplex connector for short-range optical links. Built for extended temperature operation from -40 °C to +85 °C, this SFP module fits standard SFP ports and provides a reliable uplink or interconnect option for switches, routers and media converters where extended temperature tolerance and stable optical performance are required.

Advantages

The module offers stable 2.5 Gbit/s transmission over multimode fiber while maintaining compatibility with standard SFP slots. Its industrial temperature range ensures continuous operation in extreme heat or cold, reducing the need for additional environmental controls. The LC connector and compact SFP form factor simplify installation and allow easy replacement or upgrade of existing network ports without major hardware changes.

Suitable for

• Industrial Ethernet links in factories and automation systems
• Short-range multimode fiber connections between switches and routers
• Telecommunications closets and media converter uplinks
• Environments with extended temperature requirements (outdoor cabinets, transportation, utilities)
• Network edge devices requiring compact fiber transceivers

Key specifications

• Data rate: up to 2.5 Gbit/s
• Optical fiber type: multimode fiber (MMF)
• Connector type: LC duplex
• Form factor: SFP
• Operating temperature range: -40 °C to +85 °C
• Typical application range: short-reach multimode links

How to use

Insert the SFP module into a compatible SFP port on a switch, router or media converter until it clicks into place. Connect LC duplex multimode fiber patch cords to the module’s LC ports, observing proper polarity. Ensure both ends of the link are configured for compatible data rates and fiber type; check device settings for 2.5 Gbit/s support if manual configuration is required. Monitor link status via the host device to confirm successful negotiation and optical signal presence.

Recommendations

For optimal performance, use high-quality multimode fiber and LC patch cords with proper polishing and connectors. Avoid sharp bends and maintain recommended bend radius for multimode cabling. Verify that connected equipment supports 2.5 Gbit/s operation over multimode fiber and ensure the installation environment allows operation within the -40 °C to +85 °C range.
