## Long description

The BlueOptics Fiber Optic SFP28 Transceiver CBO SFP28-25G-ESR delivers 25 Gigabit Ethernet connectivity in a compact SFP28 form factor. Intended for use in compatible switches and routers, this single-port transceiver supports 25G links over single-mode or multimode fiber (dependent on specific module variant) and is designed for straightforward installation into SFP28 slots. The module is suitable for data center uplinks, high-speed server connections and aggregation links where a compact 25G optical interface is required.
Advantages
This SFP28 transceiver offers a compact footprint with 25G performance, allowing network operators to upgrade ports without replacing existing chassis. It provides hot-pluggable installation for minimal downtime and interoperability with standard SFP28 ports in enterprise and data center equipment. The module is engineered to meet typical thermal and signal requirements for 25G Ethernet links, providing a consistent optical interface for high-bandwidth connections.
Suitable for
Data center 25G uplinks and spine-to-leaf connections
High-speed server-to-switch links
Aggregation and distribution links in enterprise networks
Network upgrades where SFP28 compatibility is required
Key specifications
Form factor: SFP28, hot-pluggable
Nominal data rate: 25 Gigabit Ethernet
Optical interface: fiber optic (single-port)
Transmission medium: fiber (single-mode or multimode depending on variant)
Typical use: short to long reach optical links depending on module variant
Compatibility: designed for use in devices with SFP28 ports
How to use
Install the transceiver into a compatible SFP28 slot on a switch or router while the host port is enabled or follow the vendor procedure for hot-plugging. Connect appropriate fiber patch cords to the optical interface, ensuring correct transmit/receive orientation and using matching fiber type for the module variant. Configure the host device port for 25G operation if required; most modern network operating systems will auto-negotiate or allow manual speed settings. Verify link status and diagnostics through the host device management interface after installation.
Usage recommendations
Use appropriate fiber patch cords and clean connectors to maintain optical performance. Confirm that the chosen module variant matches the required reach (short, medium, long) and fiber type used in the installation. Follow equipment vendor guidance for compatible transceivers and firmware to ensure full interoperability.
