## Long description

CBO AT-QSFPSR-BO is an SFP optical transceiver module operating at 850 nm designed for multimode fiber links with a reach of up to 25 km. The module offers a compact, hot-pluggable form factor that fits standard SFP ports on switches, routers and media converters. Intended for uplink and link-extension use cases, this BlueOptics transceiver provides a straightforward interface for deploying or expanding multimode fiber connections where compatible SFP sockets are available.
Advantages
The transceiver supports multimode operation at 850 nm and is engineered for compatibility with common SFP sockets, enabling quick replacement or upgrade without powering down network equipment. Its hot-pluggable design simplifies installation and maintenance, while the compact SFP size conserves module slots in dense equipment. The device is suitable for link-extension scenarios up to the specified reach and can be used in environments where a standardized optical interface is required.
Suitable for
Uplinks between switches in campus, enterprise or data center networks
Link extension between network devices over multimode fiber
Integration into routers and media converters with SFP ports
Replacement of existing 850 nm SFP modules in compatible equipment
Key specifications
Optical wavelength: 850 nm
Fiber type: multimode fiber (MMF)
Form factor: SFP (small form-factor pluggable)
Maximum reach: up to 25 km over multimode fiber (per manufacturer specification)
Interface: hot-pluggable SFP connector
How to use
Insert the transceiver into a compatible SFP port on the network device while the device is powered on to take advantage of the hot-pluggable capability. Connect the multimode fiber patch cable to the optical port, ensuring correct connector type and secure seating. Verify link status on the host device and configure link parameters if required by the switch or router. For replacement, remove the existing SFP module and insert the BlueOptics unit in the same port, then reconnect the fiber cable and confirm link operation.
Usage recommendations
Use appropriate multimode fiber and connectors rated for 850 nm operation, and follow equipment vendor guidance for supported SFP modules to ensure compatibility. Avoid bending or stressing fiber cables beyond recommended limits and inspect connectors for contamination before connection. For critical links, verify link performance and monitor signal status after installation.
