## Long description

CBO SFP28-25G-ESR-CO-BO is an SFP28 optical transceiver module supporting a 25 Gbit/s data rate with an LC duplex connector designed for single-mode fiber links. With a transmission reach of up to 300 metres, this module is intended for high-speed uplinks and direct server or switch connections in data centre and enterprise network environments. The transceiver fits SFP28 ports and supports hot-plug installation for straightforward replacement or upgrade without powering down equipment.
Advantages
This SFP28 transceiver provides 25 Gbit/s line-rate performance over single-mode fibre with low latency suitable for latency-sensitive applications. The LC connector and compact SFP28 form factor make it compatible with a wide range of network switches and servers that support SFP28 modules. Its 300 m reach covers short to medium single-mode links inside data centres or between adjacent buildings, enabling flexible deployment while keeping cabling complexity low.
Suitable for
 25 Gbit/s uplinks between switches and aggregation devices
 Server NIC connections supporting SFP28 ports
 Short-reach single-mode links inside data centres (up to 300 m)
 High-density patching panels and modular switch linecards
Key specifications

How to use
Insert the SFP28 module into a compatible SFP28 port on a switch, server NIC or transceiver cage until it latches. Connect LC-terminated single-mode fiber patch cords to the module's duplex LC port, observing correct transmit/receive orientation. Ensure connected equipment is configured for 25 Gbit/s operation and verify link status via device interfaces or LEDs. For safe removal, disable the port if required by the equipment and depress the module latch before pulling the transceiver out.
Usage recommendations
Use this transceiver in environments where single-mode 25 Gbit/s connectivity is required and fiber runs do not exceed 300 m. Verify compatibility with your network device's SFP28 port and supported optical specifications before installation, and use certified single-mode LC patch cords to maintain signal integrity.
