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

The CBO SFP28-25G-SR is a 25G fiber optic transceiver in an SFP28 form factor designed for 25 Gigabit Ethernet links over multimode fiber. It delivers high-speed data transmission for compatible switches, routers and servers with SFP28 ports. The compact module supports short-reach connections typical in data center aggregation, server interconnects and enterprise networking environments where 25G bandwidth and fiber connectivity are required.

Advantages

The transceiver offers a compact SFP28 footprint that simplifies port density and hot-pluggable maintenance. It supports 25 Gigabit Ethernet signaling over multimode fiber, enabling low-latency, high-throughput links for short-reach applications. The module is built to industry optical form-factor standards for broad compatibility with equipment that accepts SFP28 optics and provides reliable link performance in typical data center and campus cabling scenarios.

Suitable for

• 25 Gigabit Ethernet short-reach links in data centers
• Server-to-switch and switch-to-switch multimode fiber connections
• Top-of-rack aggregation and leaf-spine fabrics
• High-performance network upgrades where fiber connectivity is required

Key specifications

• Form factor: SFP28
• Data rate: 25 Gigabit Ethernet
• Fiber type: Multimode fiber (MMF)
• Reach: Short-reach (typical multimode distances, dependent on fiber type and transceiver class)
• Connector: Duplex LC
• Optical interface: 25GBASE-SR style multimode optics
• Hot-pluggable design for live equipment replacement

How to use

Install the SFP28 transceiver into a compatible SFP28 port on a switch, router or server until it latches. Connect multimode duplex LC fiber patch cables between transceiver ports. Power on and verify link status via the host device management interface; the device should auto-negotiate the 25G link if the host supports the transceiver. For proper operation, ensure the fiber type, cabling polarity and patch panel connections match the transceiver's multimode requirements.

Recommendations

Use multimode fiber of the appropriate grade (for example OM3/OM4 where applicable) and maintain clean connectors. Verify compatibility with the host equipment and confirm supported link distances for your fiber infrastructure. Replace or reseat the module while the host supports hot-plug actions and follow ESD precautions during handling.
