SFP28 25G SR Fiber Optic Transceiver CBO SFP28-25G-SR-AT-BO for short-range multimode links

The SFP28 25G SR fiber optic transceiver CBO SFP28-25G-SR-AT-BO is a compact hot-pluggable module designed for short-range multimode fiber links. It supports 25 Gigabit Ethernet transmission over multimode fiber and fits standard SFP28 ports, making it suitable for use in data center top-of-rack switches, network aggregation, and server connectivity. The module enables straightforward replacement or upgrade without powering down equipment, helping to reduce service interruptions during maintenance.

Advantages

The transceiver offers 25 Gbps data rate in a small SFP28 form factor, providing high-density port deployment while maintaining backward compatibility with SFP-based cages. Its hot-pluggable design simplifies installation and maintenance. Optimized for short-range multimode fiber, the module delivers stable optical performance and interoperability with common networking equipment. Low power consumption and a standardized interface support efficient operation in dense network environments.

Suitable for

• Data center top-of-rack and spine-leaf links
• Server-to-switch and switch-to-switch aggregation over multimode fiber
• Short-reach campus backbone and enterprise LAN connections
• High-density network deployments requiring small form-factor optics

Key specifications

• Data rate: 25 Gigabit Ethernet
• Fiber type: Multimode fiber (short-range)
• Form factor: SFP28 hot-pluggable module
• Typical reach: optimized for short-range multimode links
• Power consumption: low-power design suitable for dense deployments

How to use

Install the transceiver into a compatible SFP28 port on a switch, server NIC, or other networking device while the host is powered on if the device supports hot-plug insertion. Connect appropriate multimode duplex fiber patch cables between transceivers, ensuring correct transmit-to-receive orientation. Verify link status and configure the device network settings as required. For firmware or driver compatibility, consult the host equipment documentation to confirm support for 25G SFP28 optics.

Recommendations

Use OM3 or OM4 multimode fiber for reliable short-range performance and follow manufacturer guidelines for fiber cleaning and connector care to maintain optimal link quality. When deploying in dense racks, monitor power budget and thermal conditions to ensure stable operation.
