ALLNET ALL4757 network transceiver module 10300 Mbit/s SFP+ 850 nm

The ALLNET ALL4757 network transceiver module is a compact SFP+ optical component designed for short-range high-speed data links. With a maximum data transfer rate of 10300 Mbit/s and an 850 nm wavelength, the module supports reliable 10G-class connections over multimode fiber in data centers, aggregation switches and server uplinks. The module is hot-pluggable and compatible with standard SFP+ ports, enabling easy integration into existing network equipment that accepts SFP+ optical transceivers.

Advantages

The ALLNET ALL4757 offers a balance of small form factor and high throughput, enabling dense port configurations without sacrificing bandwidth. Its 850 nm VCSEL-based design is optimized for multimode fiber environments, providing stable performance for short-range links. The module's compatibility with common SFP+ sockets and hot-pluggable nature reduce downtime during upgrades or replacements.

Key specifications

• Interface type: SFP+
• Maximum data transfer rate: 10300 Mbit/s
• Optical wavelength: 850 nm
• Typical application: Short-range multimode fiber links
• Form factor: Small form-factor pluggable (SFP+)
• Hot-pluggable: Yes

How to use

Insert the ALLNET ALL4757 transceiver into an available SFP+ slot on a switch, router or network interface card until it seats firmly. Connect the multimode fiber patch cable (with appropriate LC connectors) to the transceiver and secure the cable to avoid strain. Ensure that the connected equipment is configured for the intended data rate and that link negotiation settings match the 10G-class operation. Monitor link status via the host device to confirm proper operation after installation.

Recommendations

Use multimode OM3/OM4 fiber for optimal short-range performance at 10300 Mbit/s and keep patch cables and connectors clean to maintain signal quality. Verify compatibility with the host device's SFP+ slot and firmware; when replacing modules in critical environments, perform a staged swap and test links to minimize service interruption.
