Fiber optic transceiver module ALLNET ALL4762

The ALLNET ALL4762 is a mini-GBIC/SFP fiber optic transceiver module designed for 1 Gigabit Ethernet over single-mode fiber with a maximum reach of up to 20 km. It integrates an FP/DFB laser transmitter, LD driver, PIN photodiode, limiting amplifier and MCU control unit in a durable metal housing and complies with the Small Form Factor Pluggable (SFP) Multi-Sourcing Agreement (MSA).

Advantages

The ALLNET ALL4762 supports a data rate of up to 1000 Mbit/s and operates from a 3.3 V supply, offering a compact SFP/mini-GBIC form factor for easy hot-pluggable installation. Its metal enclosure provides mechanical stability and thermal dissipation while the integrated optical and electronic components ensure reliable single-mode fiber transmission over distances up to 20 km. Compatibility with the SFP MSA enables vendor interoperability.

Suitable for (tasks / use cases)

• 1 Gbps uplinks between switches and routers
• Long-distance single-mode fiber connections up to 20 km
• Data center and telecom aggregation links
• Network infrastructure upgrades requiring SFP modules

How to use

Install the ALLNET ALL4762 by inserting the module into a compatible SFP slot on your switch, router or fiber transceiver port while the device is powered on or off as supported by the host. Connect single-mode fiber patch cords to the optical port, ensuring correct TX/RX orientation. Verify link status and data rate in the host device management interface. If necessary, configure the host port for 1 Gbps operation and ensure any required vendor compatibility or firmware settings are applied.

Recommendations

Use single-mode fiber with appropriate connectors (LC) and maintain proper cable routing and bend radius. Verify that the host equipment supports SFP modules and 1 Gbit/s operation. Keep the module’s metal enclosure free of debris and avoid excessive mechanical stress during insertion and removal.
