Fiber optische transceiver CBO SFP28-25G-SR 25Gb/s short-reach

The BlueOptics Fiber Optic Transceiver CBO SFP28-25G-SR is a short-reach SFP28 module engineered for 25 Gb/s links over multimode fiber. It is intended for use in compatible SFP28 cages on switches, servers and network appliances, enabling high-throughput connectivity in data center and campus environments. The transceiver supports short-distance optical links with low latency and is suitable for upgrading existing 10 Gb/s infrastructures to 25 Gb/s where fiber plant and active equipment support multimode optics.

Advantages

This SFP28 transceiver delivers 25 Gb/s serial data transmission with a compact SFP28 form factor, making it easy to install in standard SFP28 ports. The module is designed for reliable operation in dense network deployments, offering low power consumption and compatibility with common multimode fiber types for short-reach applications. Its standardized interface and optical performance reduce integration complexity when migrating to higher-speed connections.

Suitable for

• 25 Gb/s uplinks between switches in data center racks
• Server network interfaces requiring 25 GbE connectivity
• Short-reach multimode fiber links inside data centers and wiring closets
• Network upgrades from 10 GbE to 25 GbE where OM3/OM4 multimode fiber is available

Key specifications

• Form factor: SFP28
• Data rate: 25 Gigabit per second
• Reach: short-reach multimode fiber (designed for typical data center distances)
• Fiber type: multimode fiber compatibility (OM3/OM4 recommended)
• Connector: duplex LC
• Duplex communication: full duplex serial optical link
• Operating mode: hot-pluggable module for SFP28 ports

How to use

Install the transceiver into a compatible SFP28 port on the switch, server or network device until it seats securely. Connect duplex LC multimode fiber patch cords (observe correct transmit/receive orientation). Ensure the linked equipment is configured for 25 Gb/s operation and that fiber type and patch cords meet recommended multimode specifications. Monitor link status via the device management interface and replace or reseat the module if link errors or alarms appear.

Recommendations

Use OM3 or OM4 multimode fiber and high-quality duplex LC patch cords to achieve reliable short-reach 25 Gb/s links. Verify device compatibility and firmware support for SFP28 modules before installation. Protect fiber connectors from contamination and follow standard handling procedures to avoid damage to the optical interfaces.
