## Long description

CBO SFP28-25G-ESR-MA-BO is a 25 Gbit/s SFP28 optical transceiver with an LC duplex connector and a 300 m reach over multimode fiber. Designed for short-range 25G Ethernet links and data centre interconnects, this module supports hot-pluggable installation and standard SFP28 electrical and mechanical interfaces. The transceiver is intended for use in modern switches, servers and optical line cards that require reliable 25G connectivity in campus and data centre environments.
Advantages
The module provides a compact SFP28 form factor that enables high-density port deployments while maintaining 25 Gbit/s throughput. Hot-pluggable capability allows for maintenance and upgrades without powering down equipment. With an LC duplex interface and a 300 m multimode reach, it supports common short-reach multimode fiber infrastructures found in data centres and enterprise buildings. The design follows standard SFP28 electrical specifications for compatibility with a wide range of network devices.
Suitable for
 Short-range 25G Ethernet connections between switches and servers
 Data centre spine-leaf or top-of-rack interconnects on multimode fiber
 Upgrading 10G links to 25G where multimode cabling is available
 Optical uplinks for blade servers, TOR switches and NICs with SFP28 ports
Key specifications
 Nominal data rate: 25 Gbit/s
 Connector type: LC duplex
 Maximum reach: 300 m over multimode fiber
 Form factor: SFP28 (small form-factor pluggable)
 Optical type: short-range multimode transceiver

How to use
Install the SFP28 transceiver into a compatible SFP28 port on a switch, server or transceiver cage until it seats and the latch engages. Connect the LC duplex multimode fiber patch cable, ensuring correct transmit/receive alignment. The module should be recognized by equipment supporting standard SFP28 interfaces and begin operation at 25 Gbit/s. For safe removal, follow device procedures to disable the port or confirm link down status before disengaging the module to avoid data interruption.
Usage recommendations
Use high-quality multimode fiber and LC connectors rated for 25G short-reach operation, verify transceiver compatibility with your network equipment, and observe ESD precautions during installation. For best performance, keep fiber patch cables clean and within the specified maximum reach; monitor link status and error counters after installation to confirm stable operation.
