SFP28 25G SR Fiber Optic Transceiver, CBO SFP28-25G-SR — 25Gbps short-reach multimode

CBO SFP28-25G-SR is a 25 Gigabit SFP28 short-reach (SR) fiber optic transceiver designed for multimode fiber links. The module provides 25Gbps bandwidth in a compact SFP28 form factor and is intended for installation in switches, routers and network interface cards that accept SFP28 modules. It supports short-distance OM3/OM4 multimode connections typically found in data center uplinks, server interconnects and high-speed aggregation links.

Advantages

The transceiver offers high-density 25Gbps performance with a small form factor that conserves slot space while enabling higher port counts. Its multimode short-reach design reduces overall link cost for short-distance connections and simplifies cabling in rack and row topologies. Compatibility with standard SFP28 interfaces facilitates integration into existing network equipment that supports SFP28 optics.

Suitable for

• Data center switch uplinks and leaf-spine interconnects
• Server connections to top-of-rack switches
• High-speed aggregation and access links within a building or campus
• Multimode fiber runs using OM3/OM4 cabling at short distances

Key specifications

• Data rate: 25 Gigabits per second
• Form factor: SFP28
• Optical reach: short-reach multimode operation suitable for short-distance links
• Fiber type: multimode fiber (OM3/OM4 recommended)
• Connector: duplex LC
• Wavelength: short-range multimode optics (850 nm class)

How to use

Install the SFP28 module into an SFP28-compatible port on a switch, router or NIC until it latches. Connect duplex LC multimode fiber patch cords (OM3 or OM4 recommended) to the module, ensuring correct transmit/receive orientation. After connection, verify link status and interface configuration on the host device, set speed and lane parameters as required, and monitor link LEDs or management software for operational status.

Recommendations

Use clean, properly rated multimode patch cords and maintain connector cleanliness to ensure signal quality. Select OM3 or OM4 fiber for reliable 25Gbps short-reach performance and follow equipment vendor compatibility guidelines before deployment.
