Attenuatore ottico CBO SFA21BK10 monomodale LC simplex 10 dB

CBO SFA21BK10 Singlemode LC Simplex 10 dB is a fixed inline optical attenuator designed for singlemode fiber networks. It features an LC simplex connector and provides 10 dB of attenuation to reduce optical power levels between transmitting and receiving equipment. The compact LC simplex form factor allows straightforward insertion into patch cords, patch panels or equipment ports without significant space requirements.

Advantages

The attenuator offers a consistent, factory-calibrated 10 dB loss that helps prevent receiver saturation and enables proper power balancing in fiber links. Its singlemode design and LC simplex interface ensure compatibility with standard singlemode patch cords and transceivers. The compact construction minimizes insertion footprint and preserves fiber alignment for stable optical performance over time.

Suitable for

• Reducing optical power to prevent receiver overload in singlemode links
• Matching signal levels during laboratory testing or field measurement
• Inline use in patch panels, distribution frames or directly at equipment ports
• Permanent installations where fixed attenuation is required

Key specifications

• Attenuation: 10 dB (fixed)
• Fiber type: singlemode
• Connector: LC simplex
• Insertion format: inline/adapter-style
• Typical use: optical power reduction and level matching

How to use

Insert the LC simplex attenuator inline between the transmitter and receiver or into a patch cord connection where power reduction is needed. Ensure connectors are clean and undamaged before mating to maintain low return loss and avoid signal degradation. The attenuator does not require configuration; it provides the specified fixed loss once properly connected. For temporary testing, insert the attenuator into a test jumper; for permanent use, install it at the intended port in the patch panel or equipment.

Recommendations

Use a visual inspection tool or fiber inspection microscope to verify connector endface cleanliness prior to connection. Avoid excessive bending or mechanical stress on the attenuator and connected fiber; follow standard singlemode fiber handling practices. Store the attenuator in a dry, dust-free environment when not in use.
