Attenuatore in fibra ottica CBO SFA22BK15 monomodale 15 dB

BlueOptics Optical Fiber Attenuator CBO SFA22BK15 Singlemode 15 dB is a fixed-value inline attenuator for singlemode fiber networks. It provides a stable 15 dB reduction of optical power to help match transmitter output to receiver input levels, prevent receiver overload and simplify link budgeting. The attenuator is compatible with standard singlemode connectors and is suitable for use in laboratory environments, telecommunications equipment racks and data center fiber management panels where controlled signal attenuation is required.

Advantages

The fixed 15 dB attenuation delivers predictable and repeatable optical power reduction without the need for adjustment. Its inline design allows simple insertion into existing fiber links with minimal handling and low insertion loss aside from the specified attenuation. The attenuator is compact and robust for rack and field use, and it supports common singlemode connector types for broad compatibility with optical equipment.

Suitable for

• Preventing receiver saturation in singlemode fiber links
• Link budgeting and testing in laboratory environments
• Signal level control in telecommunications racks and ODF panels
• Temporary attenuation during equipment commissioning and maintenance

Key specifications

• Attenuation: fixed 15 dB
• Fiber type: singlemode
• Connector compatibility: standard singlemode connectors (plug-in inline)
• Installation type: inline/inline adapter style
• Application areas: laboratory, telecommunications, data center

How to use

Insert the attenuator between two singlemode fiber connectors by unplugging the existing connection and mating the attenuator inline. Ensure connectors are clean prior to connection to avoid contamination and additional loss. Confirm that the attenuator orientation and connector types match the link; once inserted the device provides a permanent 15 dB reduction of optical power without further adjustment. For test setups, connect test equipment after the attenuator to verify power levels.

Recommendations

Before installation, inspect and clean fiber endfaces using appropriate cleaning tools. Use optical power meters to verify that the resulting signal level after attenuation is within the receiver’s specified input range. Avoid bending the fiber excessively at the connection point and store the attenuator in protective caps when not in use to prevent contamination and mechanical damage.
