Optical Fiber Loopback Adapter DeLOCK 86921

The Optical Fiber Loopback Adapter DeLOCK 86921 is a compact SC-type loopback designed for testing and diagnosing multi-mode fiber optic links. It connects SC ports to form a loopback path so transmission and signal integrity of OM1 multi-mode fibers can be measured. The adapter has a beige housing and small footprint (25 mm × 65 mm × 11 mm) for convenient placement in test environments.

Advantages

This loopback adapter provides a standard SC interface for straightforward connection to equipment and test instruments. Its OM1 multi-mode compatibility permits accurate assessment of short-distance multimode links. The compact dimensions and durable construction make it easy to carry and position during field testing or in the lab without occupying much space.

Suitable for

• Testing and diagnostics of fiber optic ports with SC connectors
• Measuring transmission and signal integrity on OM1 multi-mode links
• Network engineering and maintenance tasks requiring loopback verification

How to use

Insert the SC connector of the loopback adapter into the SC port of the device or test equipment until it clicks into place, creating a looped optical path. Use your optical power meter, light source, or other diagnostic tools to measure transmission, return loss, or other signal parameters across the loopback. Remove the adapter by gently releasing the connector when testing is complete.

Recommendations

Store the adapter in a clean, dry place and keep connector end faces covered when not in use to avoid contamination. Use appropriate cleaning tools prior to connecting if dust or debris is present. Ensure the adapter is matched to OM1 multi-mode ports to obtain valid test results.
