Optinen vaimennin CBO SFA23BK15 yksimuotokuitu, kiinteä 15 dB

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.

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.
