SFP28 transceiver CBO SFP28-25G-ESR-VA-BO 25 Gbit/s LC multimode up to 300 m

CBO SFP28-25G-ESR-VA-BO is an SFP28 optical transceiver designed for 25 Gbit/s Ethernet links over multimode fiber. The module features an LC duplex connector and supports reach up to 300 meters on appropriate multimode fiber, providing standard 25G connectivity for switches, servers and other SFP28-capable network equipment. It is hot-pluggable for easy installation and replacement in data center and enterprise environments.

Advantages

The transceiver delivers reliable 25G performance with low power consumption in a compact SFP28 form factor. Compatibility with common SFP28 ports and support for multimode fiber up to 300 m simplify network upgrades and expand existing fiber infrastructure. Hot-pluggable design reduces downtime during maintenance, while the LC duplex interface provides industry-standard connectivity for short-reach links.

Suitable for

• 25 Gigabit Ethernet uplinks between switches and servers in data centers
• Short-reach campus and enterprise fiber links on multimode fiber
• High-density network equipment where SFP28 ports are available
• Network upgrades that require backward-compatible, compact optical modules

Key specifications

• Data rate: 25 Gbit/s
• Connector type: LC duplex
• Target fiber: Multimode fiber
• Maximum reach: up to 300 meters (on compatible multimode fiber)
• Form factor: SFP28
• Hot-pluggable: Yes

How to use

Insert the SFP28 module into a compatible SFP28 port on network equipment until it seats firmly, taking care to follow the host device manufacturer’s guidance on insertion and removal. Connect LC duplex multimode fiber patch cords with correct polarity to the module. Ensure transceiver settings and link negotiation on the switch or server are configured for 25G operation if required. Observe proper electrostatic discharge (ESD) precautions and remove protective dust caps from fiber connectors before making connections.

Recommendations

Use the module with multimode fiber of appropriate type and rated distance to achieve the specified reach. Confirm compatibility with your switch or server firmware and optical power budget during deployment. For reliable performance, maintain clean fiber connectors and follow standard cable management and environmental guidelines within data center or campus installations.
