Product information

Description

The ALLNET ALL4778 SFP28 25G singlemode transceiver delivers 25 Gbit/s optical connectivity over singlemode fibre for reaches up to 10 kilometres. Designed for use in SFP28 ports, this uncoded module supports high-speed uplinks and interconnects between switches and routers in data centre and enterprise networks. Its form factor and electrical/optical characteristics match standard SFP28 interfaces, enabling straightforward replacement or upgrade of existing 25G links.

Advantages

This SFP28 module provides a 25G singlemode optical link suitable for long-reach connections up to 10 km without dispersion compensation or additional inline devices. The uncoded design minimises protocol-specific processing on the module while maintaining compatibility with a wide range of host devices that support 25G SFP28 optics. Its compact SFP28 form factor conserves port density in switches and routers and simplifies deployment in rack environments.

Suitable for

  • 25G uplinks between switches and routers
  • Data centre interconnects over singlemode fibre
  • Enterprise backbone and campus backbone links
  • Long-reach server or aggregation links up to 10 km

Key specifications

  • Nominal data rate: 25 Gbit/s
  • Optical medium: singlemode fibre
  • Maximum reach: up to 10 kilometres
  • Form factor: SFP28
  • Coding: uncoded optical interface

How to use

Install the transceiver into an available SFP28 port on a compatible switch, router or network device while the host port is powered down or following the host manufacturer's hot-plug instructions. Connect a suitable singlemode LC fibre patch cable between the module and the remote device, ensuring correct transmit/receive orientation. Verify link status and speed in the host device management interface and confirm that the interface is configured for 25G operation and the appropriate optical settings.

Usage recommendations

Use singlemode fibre rated for long-reach connections and keep fibre connectors clean to maintain signal quality. Confirm host device compatibility with uncoded 25G SFP28 modules and ensure fibre link loss budget supports operation up to 10 km. For critical links, monitor optical power and error statistics from the host device to detect degradations early.
