ALLNET ALL4758 fibre optic transceiver module

The ALLNET ALL4758 is a universal miniGBIC SFP+ fiber optic transceiver module with an LC connector, compatible with ALLNET, 3Com, Cisco and D-Link devices. Operating at a wavelength of 1310 nm and a maximum data rate of 10000 Mbit/s, the module is intended for singlemode fiber links and is powered by 3.3 V. It supports a link range up to 10 km over 9/125 µm singlemode cable.

Advantages

The ALLNET ALL4758 combines wide vendor compatibility and SFP+ form factor flexibility in a compact transceiver. Its 1310 nm wavelength and singlemode design provide stable long-distance transmission up to 10 km, while the LC connector ensures reliable mating with common fiber patch cords. Low-voltage 3.3 V operation and support for a 10 Gbit/s-class data rate make it suitable for modern high-speed network equipment.

Suitable for

• Singlemode fiber links over distances up to 10 km
• 10 Gbit/s server uplinks, switches and routers with SFP+ ports
• Interoperability with ALLNET, 3Com, Cisco and D-Link network devices

How to use

Insert the ALLNET ALL4758 SFP+ transceiver into an available SFP+ port on a compatible switch, router or server until it clicks into place. Connect a singlemode LC fiber patch cord to the module's LC connector, ensuring correct polarity for Tx/Rx. Configure the network device as required for a 10 Gbit/s link and verify link status via the device management interface. Observe ESD precautions when handling the transceiver and remove dust caps from the LC connector only immediately before connecting.

Recommendations

Use the module with certified 9/125 µm singlemode fiber and LC patch cords for best performance. Ensure firmware or compatibility settings on the host device allow third-party SFP+ modules if the vendor enforces module validation. Keep transceiver connectors clean and capped when not in use to maintain link quality.
