BlueOptics SFP28 Fiber Optic Transceiver Module E25GSFP28SR-BO, 25 Gbps, 850 nm, LC

BlueOptics E25GSFP28SR-BO is a compact SFP28 fiber optic transceiver module designed for short-reach 25GBASE-SR links. It supports a maximum data rate of 25 Gbps (250000 Mbit/s) over multimode fiber using an 850 nm wavelength and LC duplex connector. The silver SFP28 form factor is suitable for installation in switches, routers and servers that require high-speed optical connectivity and RoHS-compliant components.

Advantages

The module provides 25 Gbps optical connectivity in a small SFP28 package, supporting industry-standard MSA mechanical and electrical interfaces. It includes digital diagnostics monitoring (DDM/DOM) for real-time parameters such as supply voltage, laser bias current, transmit power, receive power and temperature. The transceiver is manufactured to industry quality practices, delivering long service life and high availability for data center and enterprise network deployments.

Suitable for

• Short-reach 25GBASE-SR links over multimode fiber up to ~100 m
• High-density switches and routers with SFP28 ports
• Servers, storage systems and network appliances requiring 25 Gbps optical uplinks
• Environments where EMI immunity of fiber is required

Когда может не подойти

The transceiver is intended for short-reach multimode connections using 850 nm optics; it is not suitable for long-reach single-mode links or for distances beyond approximately 100 meters. Compatibility with host devices depends on vendor support for third-party SFP28 modules and the presence of required firmware features such as DDM support.

Key specifications

• Form factor: SFP28 (compact pluggable)
• Data rate: up to 25 Gbps (250000 Mbit/s)
• Wavelength: 850 nm (multimode)
• Connector: LC duplex
• Typical reach: up to 100 m on multimode fiber
• Diagnostic: DDM/DOM (digital diagnostics monitoring)
• Colour: Silver
• Operating environment: designed for standard commercial network equipment

How to use

Install the BlueOptics SFP28 module into a compatible SFP28 port on your switch, router or server with the LC duplex connector facing the fiber patch cable. Ensure the host device supports 25G SFP28 modules and that any required firmware or vendor settings allow third-party transceivers. Connect multimode fiber patch cables to the LC duplex ports and verify link status through the host device. Use the DDM/DOM interface to monitor optical parameters for troubleshooting and maintenance. Handle the module by its housing, keep dust caps on when not in use, and follow ESD precautions during installation.

What to consider before purchase

• Verify that your hardware vendor supports third-party SFP28 modules or provides a compatibility list
• Confirm required link distance and fiber type (multimode for 850 nm operation)
• Check whether DDM/DOM monitoring is needed and supported by your equipment
• Ensure your system expects LC duplex connectors and SFP28 electrical interface

Usage recommendations

Use quality multimode LC duplex patch cords and, where possible, install modules into hardware with verified compatibility. Monitor DDM values to detect degradation in transmitter or fiber performance, and keep spare modules available for quick replacement to reduce downtime.
