ALLNET ALL4755 Fibre Optic Transceiver Module

The ALLNET ALL4755 is a mini-GBIC fiber optic transceiver module designed for single-channel optical links. It supports a maximum data transfer rate of 1250 Mbit/s and operates at a wavelength of 1550 nm. The module is compact and lightweight (35 g) with a silver housing, and it requires a maximum supply voltage of 3.3 V with a typical power consumption of 1 W. The ALL4755 meets IEC-60825 safety standards for optical components and is intended for integration into networking equipment that accepts mini-GBIC form-factor transceivers.

Advantages

The ALLNET ALL4755 provides a standardized mini-GBIC interface for straightforward compatibility with switches and routers that accept SFP-style modules. Its support for a 1250 Mbit/s transfer rate and 1550 nm optical wavelength makes it suitable for typical fiber links where this specification is required. The low weight and compact dimensions simplify handling and installation, while the 3.3 V supply and 1 W typical power consumption allow integration into systems with common transceiver power budgets. IEC-60825 compliance ensures the module adheres to recognized optical safety criteria.

Suitable for

• Single-channel fiber links using mini-GBIC/SFP interfaces
• Network switches and routers that accept hot‑swap transceivers
• Point-to-point fiber connections requiring 1550 nm wavelength
• Environments where low-power, compact transceivers are preferred

How to use

Before installation, ensure the host device supports mini-GBIC/SFP modules and that the network link specifications match 1250 Mbit/s and 1550 nm wavelength requirements. With the host device powered down or following the device's hot-swap guidance, insert the ALLNET ALL4755 into the SFP slot until it seats securely. Connect the appropriate fiber optic cable with compatible connectors, verify link activity using the host equipment's indicators or management interface, and monitor for expected signal levels. Follow the host vendor's instructions for hot-plug insertion and removal if performed while powered.

Recommendations

Use clean, undamaged fiber connectors and follow standard fiber handling procedures to avoid contamination. Verify compatibility with the target switch or router and confirm that the link budget and wavelength are appropriate for the fiber span in your installation.
