SFP28 transceiver CBO SFP28-25G-ESR-MR-BO 25 Gbit/s LC duplex multimode 300 m

The BlueOptics SFP28-25G-ESR-MR-BO is a compact SFP28 optical transceiver designed for short-reach 25 Gbit/s multimode links. It fits standard SFP28 ports and provides LC duplex connectivity for multimode fiber runs up to 300 m, supporting 25 Gigabit Ethernet and other 25G high-speed networking applications. The module is hot-pluggable and intended for use with servers, switches and storage equipment where reliable short-range optical interconnects are required.

Advantages

This transceiver offers a combination of high data rate and compact form factor, enabling 25 Gbit/s performance in existing SFP28 slots. The LC duplex interface and multimode operation simplify installation in data center and enterprise fiber plants. Its hot-pluggable design reduces downtime during upgrades or replacements, while standardized form factor ensures broad compatibility with networking equipment that supports SFP28 optics.

Suitable for

• 25 Gigabit Ethernet links between switches and servers
• High-speed uplinks in data center and enterprise networks
• Short-reach optical connections in storage area networks (SAN)
• Upgrading existing multimode fiber infrastructures to 25G

Key specifications

• Data rate: 25 Gbit/s
• Fiber type: Multimode fiber (MMF)
• Maximum reach: 300 m on multimode fiber
• Connector: LC duplex
• Form factor: SFP28
• Transmission type: Optical, short reach
• Installation: Hot-pluggable

How to use

Insert the transceiver into a compatible SFP28 port on your switch, server or storage device until it latches. Connect LC duplex multimode fiber patch cables to the transceiver ports, ensuring correct transmit/receive orientation. Verify link status and speed via the host device management interface. When replacing or upgrading, remove the module using the port release mechanism and install the new transceiver while observing ESD precautions.

Recommendations

For optimal performance, use OM3 or OM4 multimode fiber to achieve the specified 300 m reach at 25 Gbit/s. Maintain clean LC connectors and follow manufacturer guidelines for handling and ESD protection. Confirm that the host device supports SFP28 optics and 25G operation before deployment.
