Transceptor SFP28 CBO SFP28-25G-ESR-DE-BO 25 Gbit/s multimodo LC, 300 m

The CBO SFP28-25G-ESR-DE-BO is a 25 Gbit/s SFP28 optical transceiver designed for multimode fiber links up to 300 m. Intended for data center and enterprise networking environments, this compact, hot-pluggable module uses a duplex LC connector and supports 25G Ethernet signalling for use in compatible switches, routers and servers. The module provides a space-saving form factor and is suitable for short-reach multimode applications where reliable, high-speed connectivity is required.

Advantages

This SFP28 transceiver delivers 25 Gbit/s data rates over multimode fiber with a reach of up to 300 m, offering a balance of speed and distance for short-reach links. The duplex LC interface ensures wide interoperability with existing fiber patching and cabling infrastructure. Hot-pluggable operation allows on-the-fly installation or replacement without powering down equipment, reducing downtime. The small SFP28 form factor is compatible with 25G-capable network ports found in modern switches, routers and servers.

Suitable for

• 25G Ethernet uplinks between switches in data center topologies
• Server-to-switch connections in high-density racks
• Short-reach aggregation links and access-layer interconnects
• Multimode fiber installations in enterprise LANs and campus networks

Key specifications

• Data rate: 25 Gbit/s
• Fiber type: Multimode fiber (MMF)
• Maximum reach: Up to 300 meters
• Connector: Duplex LC
• Form factor: SFP28, hot-pluggable
• Application: 25G Ethernet and compatible high-speed serial links

How to use

Install the module into a compatible SFP28 slot on a switch, router or server until it seats firmly; no separate power or configuration is required for basic link operation. Connect duplex multimode fiber patch cords with LC connectors to the module and to the remote transceiver, ensuring correct polarity. Verify link status through the host device's interface and monitor LEDs or management software for signal and diagnostic information. Replace or remove the module while powered on if supported by the host device to avoid service interruption.

Recommendations

Use OM3 or OM4 multimode fiber to achieve optimal performance at the specified 300 m reach. Keep fiber connectors clean and inspect or clean endfaces before connection. Follow manufacturer guidance for supported host devices and firmware compatibility to ensure proper link negotiation and diagnostics.
