It operates at a wavelength of 850 nm and is compatible with SFP28 interfaces. The module is lightweight at 40 g and comes in a silver color, making it suitable for various networking applications.

## Long description

The BlueOptics SFP28-25G-ESR-DL is an SFP28 fiber optic transceiver module engineered for 25 Gbit/s data links over multimode fiber at an operating wavelength of 850 nm. Designed for SFP28 interfaces, this compact and lightweight module (40 g) supports high-density network deployments and is compatible with equipment that accepts standard SFP28 optical modules. Its silver housing provides a durable finish suitable for racks, switches, and other networking hardware.
Advantages
This SFP28 transceiver provides a reliable 25 Gbit/s data transfer rate and is optimized for short-range multimode applications at 850 nm. Its SFP28 form factor allows hot-pluggable installation into compatible ports, minimizing downtime during upgrades or maintenance. The module’s lightweight metal housing ensures mechanical stability and good thermal performance in densely populated switch slots.
Suitable for
 25 Gbit/s server-to-switch or switch-to-switch links in data center topologies
 Short-reach multimode fiber connections within racks and between adjacent equipment cabinets
 High-density optical uplinks where SFP28 ports are used
 Network hardware that accepts standard SFP28 optical modules
Key specifications
 Interface type: SFP28 form factor, hot-pluggable
 Maximum data transfer rate: 25000 Mbit/s (25 Gbit/s)
 Operating wavelength: 850 nm for multimode fiber
 Typical application: short-range (multimode) optical links
 Weight: 0.04 kg; compact metal housing in silver color
How to use
Install the BlueOptics SFP28-25G-ESR-DL by inserting the module into a compatible SFP28 port until it latches; no additional tools are required for installation. Connect the appropriate multimode fiber patch cable with matching LC connectors and verify link status via your switch or server management interface. For safe removal, follow the host device’s hot-swap procedure: disable the port if required, release the latch, and carefully extract the module.
Usage recommendations
Use certified OM3/OM4 multimode fiber for optimal short-reach performance at 25 Gbit/s and maintain clean LC connector endfaces to prevent signal loss. Ensure the network device firmware supports third-party SFP28 modules and confirm port settings match the module’s speed and duplex capabilities.
