Fiber optic transceiver module ALLNET ALL4750-INDU

The ALLNET ALL4750-INDU is a silver-coloured SFP fiber optic transceiver module that supports up to 1000 Mbit/s data rate and operates at an 850 nm wavelength. Designed for insertion into standard SFP slots, it provides optical connectivity over multimode fiber using an LC connector and is suitable for Ethernet, telecom and Fibre Channel applications requiring short-range optical links.

Advantages

This SFP module integrates an 850 nm VCSEL laser and a PIN photodetector in a compact SFP package with an LC connector, offering transmission distances up to 550 m over 50/125 µm multimode fiber. It requires a single +3.3 V power supply, provides LVPECL-compatible data I/O, and includes low EMI design and enhanced ESD protection. The module complies with laser safety standard IEC-60825 and RoHS requirements.

Suitable for

• Short-range Ethernet links (up to 1 Gbit/s)
• Telecommunications equipment requiring multimode fiber connectivity
• Fibre Channel links over multimode fiber

Key specifications

• Interface: SFP with LC connector
• Wavelength: 850 nm (VCSEL)
• Maximum data rate: 1000 Mbit/s
• Maximum reach: up to 550 m on 50/125 µm MMF
• Power supply: +3.3 V single supply
• Data I/O: LVPECL-compatible
• Safety and compliance: IEC-60825 laser safety, RoHS compatible

How to use

Insert the ALLNET ALL4750-INDU into a compatible SFP slot of your switch, transceiver cage or media converter, ensuring the LC optical connector is properly mated to the multimode fiber patch cable. Power the host device with the standard +3.3 V supply through the SFP slot. Configure the host network equipment for 1 Gbit/s operation and verify link status using the device LEDs or management interface. For optimal performance, confirm that the fiber type is 50/125 µm MMF and that connectors are clean and undamaged.

Recommendations

Use with standard 50/125 µm multimode fiber and LC connectors; clean connectors before mating, avoid exceeding the specified maximum reach of 550 m, and follow IEC-60825 safety practices when handling optical transceivers.
