Optische verzwakker CBO SFA22BK10 singlemode, vaste 10 dB demping

The BlueOptics Optical attenuator CBO SFA22BK10 Singlemode, fixed 10 dB attenuation is a compact inline device engineered to reduce optical power by a precise, constant amount. Intended for singlemode fiber networks, this fixed 10 dB attenuator is used to protect receivers from overload, balance signal levels between links, and allow controlled signal conditions for testing and calibration. Its inline form factor and singlemode compatibility make it suitable for installation in telecom, datacom and laboratory environments where predictable attenuation is required.

Advantages

This fixed singlemode attenuator provides a stable 10 dB reduction of optical power with consistent performance across standard operating conditions. The inline design enables simple insertion into existing fiber runs without altering connector arrangements. Because the attenuation value is fixed, the device offers repeatable results for measurement and commissioning tasks and reduces the need for frequent adjustments. The small, robust construction supports reliable long-term use in field and lab settings.

Suitable for

• Protecting optical receivers from high input power
• Adjusting signal levels in singlemode fiber links
• Optical test setups and calibration in laboratories
• Telecommunications and datacom installations requiring fixed attenuation

Key specifications

• Mode: singlemode fiber
• Attenuation: fixed 10 dB
• Form factor: inline connectorized attenuator
• Typical use: signal level reduction and calibration
• Compatibility: standard singlemode fiber connectors and equipment

How to use

Install the attenuator inline between two singlemode fiber connectors by mating the connector ends as required; ensure connectors are clean before insertion to prevent contamination. Place the attenuator on the transmit or receive side according to the required direction of power reduction. Verify system performance after installation using an optical power meter or the target device to confirm the expected 10 dB reduction. For testing or measurement workflows, document the attenuator location and measured values to maintain repeatability.

Recommendations

Clean fiber connectors before connecting the attenuator and avoid excessive bending of the fiber near the inline device. Use the attenuator in applications where a fixed, known attenuation is acceptable; for variable control, select an adjustable attenuator instead. Confirm connector compatibility and inspect the attenuator for physical damage before use.
