## Summary description

CBO SFA23BK15 is a singlemode optical fiber attenuator with a fixed attenuation of 15 dB. Designed for inline use in fiber optic links, it reduces signal power to prevent receiver overload and to balance channel levels. Suitable for testing, installation and maintenance of singlemode networks where controlled optical attenuation is required.

## Long description

The BlueOptics Optical Fiber Attenuator CBO SFA23BK15 singlemode, fixed 15 dB is a compact inline attenuator intended for singlemode fiber links. It provides a precise, fixed attenuation of 15 dB to reduce optical power levels and prevent receiver saturation. The attenuator is designed for use in installations, maintenance and testing of singlemode networks where consistent optical attenuation is required to balance channels or adapt signal levels to receiver sensitivity.
Advantages
This fixed 15 dB attenuator delivers stable attenuation without the need for adjustment, ensuring repeatable performance in the field. Its inline construction allows straightforward insertion into fiber runs or patch panels with minimal disruption. The device is manufactured to provide low back-reflection and consistent optical characteristics across standard operating wavelengths for singlemode systems. The compact design supports easy handling during installation and storage.
Suitable for
 Balancing optical power between channels in singlemode transmission links
 Preventing receiver overload in optical transceivers and modules
 Field testing and commissioning of singlemode fiber networks
 Temporary or permanent inline attenuation in patch panels and fiber trays
Key specifications
 Fiber type: singlemode
 Attenuation: fixed 15 dB
 Form factor: inline attenuator for connectorized fiber links
 Optical performance: low back-reflection suitable for singlemode systems
 Typical use: installation, testing and maintenance of singlemode networks
How to use
Insert the attenuator inline between two connectorized fiber ends or attach it to an optical transceiver port as required. Ensure connectors are clean and properly mated to maintain low insertion loss aside from the specified attenuation. Confirm that the fixed 15 dB reduction is appropriate for the target receiver sensitivity and overall link budget before deployment. For testing, include the attenuator in the measurement path to simulate expected operating power levels.
Usage recommendations
Handle connectors with care and keep protective caps on when the attenuator is not in use. Verify connector cleanliness with an inspection tool before connecting. Use the attenuator in accordance with system link budget calculations and manufacturer guidance for transceivers to avoid under- or over-attenuation of signals.
