## Summary description

ALLNET ALL4791 SFP module provides 2.5 Gbit/s optical connectivity over singlemode fiber with an LC connector. Designed for network equipment with SFP slots, it enables uplinks or links between switches, routers and media converters. Ideal for extending reach over long distances, it delivers reliable high-speed transmission for enterprise and carrier networks.

## Long description

ALLNET ALL4791 SFP module provides 2.5 Gbit/s optical connectivity over singlemode fiber using an LC connector. Designed for installation in standard SFP slots, this transceiver enables high-speed uplinks and point-to-point links between switches, routers and media converters. The compact form factor and singlemode optics are intended for extended reach applications where reliable transmission and low-latency performance are required in enterprise and carrier networks.
Advantages
The SFP module supports 2.5 Gbit/s throughput over singlemode fiber while maintaining a small, hot-pluggable form factor compatible with equipment that accepts SFP transceivers. The LC connector provides a secure fiber interface and the singlemode optics are optimized for longer-distance links compared to multimode alternatives. The module is suitable for mixed-speed environments and can be applied to upgrade existing infrastructure to intermediate speeds without replacing SFP-based ports.
Suitable for
 2.5 Gbit/s uplinks between switches and aggregation devices
 Long-distance point-to-point fiber links in enterprise and carrier networks
 Interconnection of routers, switches and media converters with SFP slots
 Upgrading access networks to intermediate speeds where singlemode fiber is used
Key specifications
 Data rate: 2.5 Gbit/s
 Fiber type: singlemode
 Connector: LC duplex
 Form factor: SFP (small form-factor pluggable)
 Application: optical uplink / point-to-point transmission
How to use
Insert the SFP module into a compatible SFP slot on the switch, router or media converter while the device is powered according to the equipment vendor's guidelines. Connect singlemode LC fiber patch cords to the module's LC ports, observing correct transmit/receive orientation. Configure the network device port for the required speed and duplex settings if manual configuration is required; otherwise allow the device to negotiate link parameters automatically. Monitor link status LEDs and device logs to confirm successful link establishment.
Usage recommendations
Ensure that connected fiber cables are clean and undamaged, use dust caps when ports are unused, and follow ESD precautions while handling the module. Verify compatibility with the host device's SFP interface and consult the network equipment documentation for supported transceiver profiles and firmware requirements.
