## Long description

The CBO SFP28-25G-ESR-DE-BO is a 25 Gbit/s SFP28 optical transceiver designed for multimode fiber links up to 300 m. Intended for data center and enterprise networking environments, this compact, hot-pluggable module uses a duplex LC connector and supports 25G Ethernet signalling for use in compatible switches, routers and servers. The module provides a space-saving form factor and is suitable for short-reach multimode applications where reliable, high-speed connectivity is required.
Advantages
This SFP28 transceiver delivers 25 Gbit/s data rates over multimode fiber with a reach of up to 300 m, offering a balance of speed and distance for short-reach links. The duplex LC interface ensures wide interoperability with existing fiber patching and cabling infrastructure. Hot-pluggable operation allows on-the-fly installation or replacement without powering down equipment, reducing downtime. The small SFP28 form factor is compatible with 25G-capable network ports found in modern switches, routers and servers.
Suitable for
 25G Ethernet uplinks between switches in data center topologies
 Server-to-switch connections in high-density racks
 Short-reach aggregation links and access-layer interconnects
 Multimode fiber installations in enterprise LANs and campus networks
Key specifications
 Data rate: 25 Gbit/s
 Fiber type: Multimode fiber (MMF)
