CBO Transceiver SFP28-25G-ESR BO27Q856S3D 25G Fiber Optic SFP28 Module

The CBO Transceiver SFP28-25G-ESR BO27Q856S3D 25G Fiber Optic SFP28 Module is a compact, hot-pluggable optical transceiver designed to deliver 25 Gigabit Ethernet connectivity over single-mode or specified multimode fiber for short- to medium-range links. Intended for installation in standard SFP28 ports, the module provides a low-latency physical link for switches, routers and servers in data center and enterprise networks while supporting straightforward upgrades of existing infrastructure.

Advantages

This SFP28 module offers 25G line rate performance in a small form factor that fits SFP28-compatible equipment, enabling denser port deployment without changing chassis or line cards. Its hot-pluggable design allows replacement or upgrade without powering down the host device, reducing maintenance windows. The module is engineered for reliable optical links with consistent data throughput and low latency suitable for high-performance networking environments.

Suitable for

• 25 Gigabit Ethernet connections between switches and aggregation devices
• Server uplinks and direct server-to-switch links in data centers
• Short- to medium-distance optical links within campus and enterprise networks
• Upgrading 10G ports to 25G where SFP28 slots are available

Key specifications

• Form factor: SFP28 small form-factor pluggable
• Data rate: 25 Gigabit per second
• Optical interface: fiber optic duplex (LC) compatible
• Reach: designed for short- to medium-range optical links (see vendor documentation for exact distance based on fiber type)
• Compatibility: designed for standard SFP28 ports in switches, routers and servers
• Installation: hot-pluggable
• Latency: optimized for low-latency data transmission

How to use

Install the transceiver into a compatible SFP28 port on the target switch, router or server by aligning the module and gently inserting until it clicks into place. Connect the appropriate duplex fiber patch cable (LC) to the transceiver's optical ports, ensuring correct transmit/receive orientation. Configure the host device's interface settings as required for 25G operation and monitor link status through the device management interface. To remove the module, power down the link if recommended by the equipment vendor, release the latch and pull the module straight out.

Recommendations

Use single-mode or the specified multimode fiber and LC duplex patch cables that meet the required attenuation and bandwidth characteristics for the intended reach. Verify compatibility with the host device's firmware and transceiver support list, and follow electrostatic discharge (ESD) precautions during handling and installation to avoid damage to the optical interface.
