SFP28 transceiver module BlueOptics SFP28-25G-SR-DE 25000 Mbit/s 850 nm

The BlueOptics SFP28-25G-SR-DE is a fiber optic SFP28 transceiver module designed for 25 Gbit/s short-reach links. It operates at an 850 nm wavelength and supports a maximum data transfer rate of 25,000 Mbit/s. The module is compact, lightweight (approximately 20 g) and available in a silver housing, making it suitable for installation in high-density network equipment in data centers and enterprise environments.

Advantages

The SFP28 form factor provides compatibility with 25 G Ethernet ports while keeping physical space and power usage low. Operating at 850 nm, the module is optimized for multimode fiber short-reach connections, offering predictable performance for switch-to-switch and server-to-switch links. Its lightweight metallic housing simplifies handling and insertion into SFP28 slots and supports hot-plug capability for minimal disruption during maintenance.

Suitable for

• 25 G Ethernet uplinks in data centers
• Server-to-switch and switch-to-switch short-reach connections
• Enterprise network segments requiring compact transceivers
• High-density patch panels and modular switch ports

Key specifications

• Interface type: SFP28
• Maximum data transfer rate: 25,000 Mbit/s
• Optical wavelength: 850 nm
• Typical reach: designed for short-reach multimode fiber links
• Construction: compact SFP28 metallic housing, silver colour
• Weight: approximately 0.02 kg

How to use

Ensure the host port supports SFP28 25 G modules and that the fiber type and connectors match the module requirements. With the network equipment powered on, insert the transceiver into the SFP28 slot until it clicks into place and secure any latch or retention mechanism. Connect the multimode fiber patch cord to the module’s optical interface, observing correct polarity. Once connected, verify link status and configure the port settings in the switch or server operating system as required.

Recommendations

Use multimode fiber (OM3/OM4) for expected short-reach performance at 850 nm and follow manufacturer guidelines for cleaning fiber endfaces before connection. Store and handle the module using ESD precautions and keep dust caps on unused optical ports to prevent contamination.
