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

The Transceiver CBO SFP28-25G-ESR Fiber Optic 25G is a compact SFP28 optical module designed for 25 Gigabit Ethernet links in data centers and enterprise networks. Compatible with the Allied Telesis form factor, this BlueOptics transceiver delivers a high-density solution for uplinks, server connections and switch-to-switch interconnects. It supports short- to extended-reach multimode or single-mode deployments depending on the optical variant, providing reliable optical connectivity for high-throughput environments.

Advantages

This 25G SFP28 module offers a compact size compatible with commonly used switch slots and supports high-bandwidth connections while keeping power consumption low. The transceiver is manufactured to meet industry interoperability expectations for form-factor compatibility, enabling straightforward replacement or upgrade of existing ports. Its optical design reduces latency and provides stable signal integrity for demanding network applications.

Suitable for

• Server uplinks and top-of-rack switch connections
• Switch-to-switch aggregation and spine links in data centers
• Enterprise LAN backbones and campus distribution
• High-performance computing clusters and virtualized environments

Key specifications

• Interface: SFP28 form factor for 25 Gigabit Ethernet
• Data rate: 25 Gbps
• Optical medium: fiber optic (short- to extended-reach variants possible)
• Connector type: LC duplex (typical for 25G fiber transceivers)
• Power consumption: low-power SFP28-class operation
• Operating temperature: industrial or commercial ranges depending on variant

How to use

Install the transceiver into a compatible SFP28 port until it clicks into place, taking care to align the module with the host device slot. Connect the appropriate fiber optic cable with LC duplex connectors and secure any dust caps until final installation to protect the optical interface. Configure the host network device for 25G operation as required by the switch or server management interface. Monitor link status and diagnostics via the host system to verify signal integrity and operational parameters.

Usage recommendations

Ensure compatibility with the target switch or server by confirming support for Allied Telesis form-factor compatible SFP28 transceivers and verify the required reach (short, intermediate or extended) and fiber type before purchase. Handle the optical connectors carefully, keep dust caps on when not in use, and follow standard electrostatic discharge precautions during installation.
