## Summary description

CBO SFA24BK15 is a singlemode optical attenuator providing 15 dB fixed attenuation. Designed for fiber-optic networks, it reduces signal power to prevent receiver overload and support link testing and power balancing. Compact and passive, it requires no power source and is suitable for installations, maintenance, lab measurements, and field use where controlled attenuation is needed.

## Long description

The BlueOptics Optical attenuator CBO SFA24BK15 Singlemode 15 dB is a fixed inline fiber device that reduces optical power by 15 dB in singlemode links. It is a compact, passive component intended for fiber-optic networks, laboratory measurements and field testing where controlled attenuation is required to protect receivers from overload, to balance link power levels or to simulate longer spans for diagnostics. The attenuator is designed for straightforward integration into existing singlemode installations and does not require an external power source.
Advantages
This singlemode 15 dB attenuator offers stable, predictable attenuation and simple plug-and-play use. Its passive design ensures low maintenance and continuous operation without power. The compact construction minimizes insertion footprint in patch panels or test configurations while preserving signal integrity through controlled attenuation.
Suitable for
 Balancing transmitter and receiver power levels in singlemode optical links
 Protecting sensitive receivers from high optical power
 Field testing and commissioning of fiber-optic networks
 Laboratory measurements and optical link troubleshooting
 Simulating additional fiber link loss during system validation
Key specifications
 Type: Fixed optical attenuator
 Mode: Singlemode
 Attenuation: 15 dB (fixed)
 Operation: Passive, no external power required
 Typical application: Inline attenuation for links, testing and measurement
 Form factor: Compact inline connectorized unit suitable for patch panels and test leads
How to use
Install the attenuator inline between the optical transmitter or patchcord and the receiver or measurement instrument by connecting matching singlemode connectors. Ensure connectors are clean before mating to avoid contamination-related loss. For testing, insert the attenuator at the desired point in the link and verify received power levels with an optical power meter or network equipment to confirm correct attenuation. When not in use, protect connector ends with dust caps.
Usage recommendations
Use appropriate connector types that match your system (for example LC or SC singlemode) and always perform connector cleaning and inspection before insertion. Store the attenuator in a dry, dust-free environment and avoid excessive bending or tensile loading on connected fiber to maintain performance.
