SFP-module ALLNET ALL4791-INDU 2,5 Gbit/s Singlemode LC -40 tot +85 °C

The ALLNET ALL4791-INDU SFP module delivers 2.5 Gbit/s singlemode fiber connectivity through an LC connector and is engineered for industrial environments. Compatible with standard SFP ports, this optical transceiver provides a compact, hot-pluggable solution for adding a high-speed uplink to switches, routers or media converters. Its extended operating temperature range from -40 to +85°C makes it suitable for outdoor cabinets, factory floors and other harsh environments where reliable fiber links are required.

Advantages

The module offers a robust industrial design with extended temperature tolerance for dependable operation in extreme climates. With 2.5 Gbit/s throughput on a singlemode fiber interface and a standard LC connector, it supports higher-than-1G links without changing existing SFP slots. The hot-pluggable form factor enables easy field replacement or upgrades, and compatibility with common network equipment simplifies installation and integration into existing fiber infrastructures.

Suitable for

• High-speed uplinks in industrial Ethernet switches and routers
• Fiber backbone connections in outdoor or harsh-environment installations
• Media converters and network devices requiring 2.5 Gbit/s singlemode links
• Telecommunications closets and aggregation points with LC fiber cabling

Key specifications

• Data rate: 2.5 Gbit/s
• Fiber type: Singlemode
• Optical connector: LC
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Operating temperature range: -40°C to +85°C
• Typical application: uplink/aggregation on switches, routers, media converters

How to use

Insert the SFP module into a compatible SFP port on your switch, router or media converter while the device is powered down or hot-plug according to the equipment's guidelines. Connect a singlemode LC fiber patch cable to the module's LC receptacle, ensuring correct polarity and secure connection. Verify link status and speed through the host device's management interface and monitor optical parameters if supported. For reliable operation, ensure fiber connectors are clean and mating adapters are compatible with LC singlemode components.

Recommendations

For optimal performance, install the module in equipment that supports 2.5 Gbit/s SFP transceivers and operate within the specified -40 to +85°C temperature range. Use quality singlemode fiber and LC connectors, keep connectors free of dust, and follow manufacturer guidelines for ESD protection and mechanical handling during installation.
