## Summary description

Passive optical attenuator CBO SFA22BK7, 7 dB attenuation for singlemode fiber with SC simplex connector. Designed to reduce optical signal power to prevent receiver overload, test networks, or balance link budgets. Compact inline unit suitable for telecom, datacom and laboratory use; simple plug-and-play installation.

## Long description

Optical Fiber Attenuator CBO SFA22BK7 7 dB Singlemode SC Simplex is a passive inline device designed to reduce optical signal power in singlemode fiber links. The attenuator provides a fixed 7 dB attenuation and uses an SC simplex connector for straightforward plug-and-play integration. Its compact form factor makes it suitable for installation in telecom cabinets, patch panels, test setups and laboratory benches where controlling signal power is necessary to protect receivers or to balance link budgets.
Advantages
The attenuator delivers a stable, repeatable 7 dB loss without active components, ensuring minimal maintenance and consistent performance over time. Its singlemode design and SC simplex interface offer wide compatibility with common network equipment and test instruments. The compact, robust housing facilitates easy handling and reliable mechanical connection in field and lab environments.
Suitable for
Preventing receiver overload in singlemode optical links
Balancing optical power levels across fiber connections
Laboratory testing and measurement of fiber-optic equipment
Temporary insertion into patch panels and field verification tasks
Key specifications
Attenuation: fixed 7 dB
Fiber type: singlemode
Connector type: SC simplex
Form factor: inline/passive attenuator
Installation: plug-and-play inline insertion
How to use
Insert the SC simplex connector of the attenuator into the SC receptacle of the transmitter, patch cord, or equipment port, then connect the other fiber end to the receiver or downstream device. Ensure connectors are clean before mating to prevent contamination and loss. The device requires no power or configuration; the fixed attenuation takes effect immediately upon insertion. For repeated use, handle connectors by the housing and store with protective caps when not in use.
Usage recommendations
For reliable results, clean fiber end-faces with an appropriate fiber cleaning tool before connecting. Use this 7 dB fixed attenuator when a specific reduction in optical power is required; for variable conditions, consider using adjustable attenuators. Avoid bending the fiber near the connector beyond its minimum bend radius and keep the attenuator in a dry, dust-free environment.
