Transceiver CBO SFP28-25G-SR Fiber Optic 25G

The Transceiver CBO SFP28-25G-SR Fiber Optic 25G is a compact SFP28 module engineered for short-range 25 Gigabit Ethernet links over multimode fiber. Designed to fit standard SFP28 ports, this BlueOptics transceiver enables high-bandwidth connectivity for server uplinks, switch-to-switch aggregation and intra-rack connections. The module follows SR (short reach) specifications to deliver reliable, low-latency transmission in data centre and enterprise LAN environments.

Advantages

The transceiver offers 25G data-rate support in an industry-standard SFP28 form factor, enabling straightforward upgrades of existing SFP28-capable switches and routers. Its multimode fiber compatibility reduces installation complexity for short-distance links and supports cost-effective cabling. The module is designed for interoperability with common network equipment, focusing on stable signal quality and consistent performance for aggregation and uplink applications.

Suitable for

• Server uplinks in data centres and server rooms
• Switch-to-switch aggregation within racks and across adjacent racks
• High-density switch deployments requiring 25G short-reach links
• Enterprise LAN backbones and core distribution layers

Key specifications

• Form factor: SFP28 (25G capable)
• Data rate: 25 Gigabit Ethernet
• Fiber type: Multimode fiber (MMF)
• Reach: Short range (designed for SR links within data centres)
• Optical interface: Duplex LC connector
• Wavelength: Short-reach multimode optical wavelength
• Operating environment: Designed for typical data centre operating temperatures

How to use

Install the transceiver into an available SFP28 slot on a compatible switch, router or network interface card following the equipment manufacturer’s hot-plug procedures. Connect duplex LC multimode fiber patch cords to the module and ensure proper transmit/receive alignment. Verify link status via the host device management interface and monitor port LEDs or system logs to confirm operational 25G connectivity. For best results, use multimode fiber and patch cords that meet SR reach and attenuation requirements.

Recommendations

To maintain optimal performance, ensure fiber cabling and patch panels are clean and properly rated for 25G SR connections. Match transceiver specifications with your switch/router ports and verify compatibility in the equipment documentation. When deploying in dense installations, plan for adequate cooling and follow the host device vendor guidelines for transceiver support and firmware updates.
