SFP28 transceiver module BlueOptics SFP28-25G-ESR-DL 25000 Mbit/s 850 nm

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.

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.
