## Summary description

Extralink EX.31306 is an SFP28 optical transceiver module supporting 25G data rate over multimode fiber using 850 nm wavelength. Designed for short-reach links up to 100 meters, it fits SFP28 ports for high-speed server, switch or storage interconnects, enabling low-latency 25GbE connections in data centers and enterprise networks.

## Long description

Extralink EX.31306 is an SFP28 optical transceiver module that provides 25 Gigabit Ethernet connectivity over multimode fiber using an 850 nm wavelength. Engineered for short-reach links, this module supports reliable data transmission up to 100 meters and is compatible with SFP28 ports used in servers, switches and storage interfaces. The compact form factor and single-lane 25G data rate make it suitable for dense, low-latency connections in data center top-of-rack and aggregation environments.
Advantages
The module delivers a standardized 25G interface in an SFP28 footprint, enabling higher port density and simplified upgrades from 10G systems. With multimode fiber support and an 850 nm VCSEL-based optical interface, it offers low-power operation suitable for high-density racks. The design focuses on interoperability with common switch and server platforms, ease of installation in SFP28 sockets, and predictable short-reach performance for intra-rack and adjacent-rack links.
Suitable for
 25GbE short-reach connections within data centers
 Server-to-switch and switch-to-switch links up to 100 m
 High-density rack deployments and top-of-rack uplinks
 Storage area network (SAN) interconnects requiring low latency
Key specifications
 Form factor: SFP28 single lane 25G optical transceiver
 Data rate: 25 Gigabit per second
 Wavelength: 850 nm (multimode)
 Maximum reach: up to 100 meters on multimode fiber
 Connector type: LC duplex
 Optical interface: short-reach multimode VCSEL
 Operating temperature range: typical commercial-range operation
How to use
Install the transceiver into an available SFP28 port until it latches, then connect LC duplex multimode fiber patch cords to the module and corresponding equipment ports. Ensure the connected fiber type and transceiver reach match the planned link distance (up to 100 m on multimode). Verify link status and speed through the host device management interface and monitor diagnostics where supported. Follow standard electrostatic discharge (ESD) precautions during handling and avoid removing dust caps until ready to mate fibers.
Usage recommendations
Use OM3 or OM4 multimode fiber for optimal performance at maximum distances, keep patch cords and connectors clean, and confirm compatibility with the host equipment's SFP28 ports. For best results in high-density environments, plan airflow and power budgets to account for multiple active transceivers.
