Fibre Optic Transceiver Module ALLNET ALL4761

The ALLNET ALL4761 is an SFP fiber optic transceiver module for single-mode fiber links, supporting a maximum data rate of 1250 Mbit/s and a transmission distance up to 20 km. The module operates at a wavelength of 1490 nm, uses a metal housing for protection, and is compatible with the Small Form Factor Pluggable (SFP) Multi-Sourcing Agreement (MSA). It requires a supply voltage of 3.3 V with typical power consumption around 1.2 W and integrates transmitter and receiver sections including laser driver, PIN photodiode and control electronics.

Advantages

The ALLNET ALL4761 provides a compact SFP form factor suitable for hot-pluggable network installations and meets SFP MSA compatibility for broad interoperability. Its metal housing enhances mechanical durability and thermal performance, while the specified 1490 nm wavelength and single-mode design enable reliable long-distance links up to 20 km. Low typical power consumption helps reduce operating power in rack-mounted equipment.

Suitable for

• Single-mode fiber uplinks in enterprise and carrier networks
• Access and metro fiber connections up to 20 km
• Network switches, routers and media converters with SFP ports

How to use

Insert the ALLNET ALL4761 into an available SFP slot on a compatible switch, router or media converter while the host device is powered according to the vendor instructions for hot-plugging. Connect a single-mode fiber cable with appropriate connectors (matching the transceiver port) and verify link status via the host device LEDs or management interface. Ensure the host device is configured for the correct data rate and wavelength where applicable.

Recommendations

Use factory-terminated single-mode fiber with correct connector types, keep fiber ends clean to avoid signal loss, and follow ESD precautions when handling the module. Confirm compatibility with your network equipment's SFP module list and firmware for reliable operation.
