ALLNET ALL4752 Fibre Optic Transceiver Module

The ALLNET ALL4752 is a mini-GBIC/SFP fiber optic transceiver module designed for single-channel data links. Supporting a maximum data transfer rate of 1250 Mbit/s and operating at a wavelength of 1310 nm, this compact module provides a standard optical interface for short- to medium-range network connections. The transceiver runs from a 3.3 V supply and, at 35 g, is lightweight for easy insertion into compatible SFP ports. Its silver housing offers a neutral appearance for rack-mounted or desktop networking equipment.

Advantages

The ALLNET ALL4752 offers a standard mini-GBIC/SFP form factor compatible with many switches, routers and media converters. With a 1250 Mbit/s maximum throughput and 1310 nm wavelength it supports common fiber network architectures. The low operating voltage and small physical size simplify deployment and replacement, while the lightweight metal housing contributes to durability and electromagnetic shielding.

Suitable for

• Migration from copper to fiber links in local area networks
• Interconnection of switches and routers over single-mode fiber
• Use in SFP-capable switches, routers and media converters
• Replacement or spare transceiver modules for existing fiber infrastructure

How to use

Ensure the host device supports SFP transceivers and that the fiber cabling type matches the transceiver wavelength and connector type. Power down the SFP port if the host device requires hot-swap protection, or follow the device manufacturer's hot-plug procedure. Align the module with the SFP cage and gently insert until it latches; verify link status via the host device's indicators or management interface. If necessary, configure port speed and duplex settings on the host to match network requirements. When removing, release the latch and pull the module straight out to avoid damaging the cage or fiber connector.

Recommendations

Store and handle the module in a dry, dust-free environment; keep protective caps on optical interfaces when not connected. Verify compatibility with the network device vendor and test link integrity after installation. For optimal performance, use single-mode fiber cabling that corresponds to the 1310 nm wavelength and follow proper fiber handling practices to avoid contamination or bend losses.
