CBO SFA24BK15 optikai csillapító egymódusú 15 dB

The BlueOptics Optical attenuator CBO SFA24BK15 Singlemode 15 dB is a fixed inline fiber device that reduces optical power by 15 dB in singlemode links. It is a compact, passive component intended for fiber-optic networks, laboratory measurements and field testing where controlled attenuation is required to protect receivers from overload, to balance link power levels or to simulate longer spans for diagnostics. The attenuator is designed for straightforward integration into existing singlemode installations and does not require an external power source.

Advantages

This singlemode 15 dB attenuator offers stable, predictable attenuation and simple plug-and-play use. Its passive design ensures low maintenance and continuous operation without power. The compact construction minimizes insertion footprint in patch panels or test configurations while preserving signal integrity through controlled attenuation.

Suitable for

• Balancing transmitter and receiver power levels in singlemode optical links
• Protecting sensitive receivers from high optical power
• Field testing and commissioning of fiber-optic networks
• Laboratory measurements and optical link troubleshooting
• Simulating additional fiber link loss during system validation

Key specifications

• Type: Fixed optical attenuator
• Mode: Singlemode
• Attenuation: 15 dB (fixed)
• Operation: Passive, no external power required
• Typical application: Inline attenuation for links, testing and measurement
• Form factor: Compact inline connectorized unit suitable for patch panels and test leads

How to use

Install the attenuator inline between the optical transmitter or patchcord and the receiver or measurement instrument by connecting matching singlemode connectors. Ensure connectors are clean before mating to avoid contamination-related loss. For testing, insert the attenuator at the desired point in the link and verify received power levels with an optical power meter or network equipment to confirm correct attenuation. When not in use, protect connector ends with dust caps.

Recommendations

Use appropriate connector types that match your system (for example LC or SC singlemode) and always perform connector cleaning and inspection before insertion. Store the attenuator in a dry, dust-free environment and avoid excessive bending or tensile loading on connected fiber to maintain performance.
