## Summary description

Inline fiber optic attenuator CBO SFA24BK1 for singlemode networks with 1 dB attenuation. Designed to reduce optical signal power between components, it helps prevent receiver overload and optimize link budgets. Compact, inline design is suitable for patch panels, splice boxes and field installations in telecom and data center applications.

## Long description

The BlueOptics Fiber optic attenuator CBO SFA24BK1 Singlemode 1 dB is an inline optical attenuator designed for singlemode fiber networks. Its purpose is to reduce optical signal power by 1 dB to prevent receiver saturation and to help balance link budgets in telecommunication and data center environments. The compact, inline format is suitable for installation in patch panels, splice boxes and field cabling runs where precise, low-loss attenuation is required.
Advantages
This inline attenuator provides a stable, specified attenuation of 1 dB with minimal insertion loss and back reflection, ensuring predictable performance in singlemode links. The small form factor and standardized singlemode interfaces allow easy integration into existing fiber infrastructure without the need for additional adapters. The device is engineered for consistent optical characteristics across typical operating conditions, enabling reliable signal level control in sensitive receiver scenarios.
Suitable for
 Balancing optical power levels between transmitters and receivers in singlemode networks
 Preventing receiver overload in telecom and data center links
 Inline installation in patch panels, splice enclosures and field cabling
 Laboratory and test setups where small, fixed attenuation is required
Key specifications
 Attenuation: 1 dB (fixed)
 Fiber type: singlemode
 Format: inline attenuator for fiber patching
 Typical insertion loss: minimal beyond specified attenuation (manufacturer tolerance applies)
 Connector compatibility: designed for standard singlemode connector interfaces
 Application environment: telecom, data center, field installations, test environments
How to use
Install the attenuator inline between two singlemode fiber connectors, ensuring clean connector end-faces before connection to avoid contamination and additional loss. Connect one end to the transmitting side and the other end to the receiving side so that the optical signal passes through the attenuator. Verify signal levels after installation using an optical power meter or the system receiver to confirm the 1 dB reduction and that the resulting power is within acceptable receiver range.
Usage recommendations
Always inspect and clean fiber connectors prior to mating, and avoid excessive bending or mechanical stress on the inline attenuator. Use appropriate connector dust caps when the device is not in use. For critical links, measure optical power before and after installation to document the effect of the attenuator and ensure compliance with system link budget requirements.
