ALLNET ALL4750 Network Switch Module

Universal miniGBIC SX module with LC connector, compatible with ALLNET, Cisco and D-Link devices. The module supports 1.125 Gbps transmission at 850 nm over multimode fiber and conforms to SFP form factor, enabling high-speed optical links for network switches and compatible transceivers.

Advantages

The ALLNET ALL4750 offers broad vendor compatibility (ALLNET, Cisco, D-Link) in an SFP package with LC duplex connector. It operates at 850 nm for multimode fiber and supports 1.125 Gbps data rates, providing a standardized, hot-pluggable solution for adding fiber interfaces to network equipment while keeping installation and replacement straightforward.

Suitable for

• Expanding switch ports to fiber on compatible ALLNET, Cisco and D-Link switches
• Short-distance multimode fiber links inside buildings and campus networks
• Replacing or upgrading existing SFP SX modules in managed and unmanaged switches

How to use

Insert the ALLNET ALL4750 SFP module into an empty SFP slot on a compatible switch or transceiver host while the device is powered on or off according to the host’s hot-plug guidance. Connect LC duplex multimode fiber patch cables to the module’s LC connectors, observing correct transmit/receive orientation. Configure the switch port as needed (speed/duplex or fiber port settings) and verify link status in the network management interface.

Recommendations

Use multimode fiber with appropriate attenuation and patchcords rated for 850 nm. Verify device compatibility and any required firmware or port settings on ALLNET, Cisco or D-Link equipment before deployment. Handle the LC connectors and SFP module with care to avoid contamination or damage to the optical interfaces.
