Optische vezel loopback-adapter DeLOCK 86931

The Optical Fiber Loopback Adapter DeLOCK 86931 is a compact LC/OM3 multimode loopback designed for testing and troubleshooting fiber optic links. With a length of 0.06 m and a 50 µm core diameter, this loopback enables measurement of transmission capability and verification of full-duplex operation on LC-terminated multimode cabling.

Advantages

This DeLOCK loopback adapter provides a simple and reliable means to test optical fiber ports and channels without requiring additional active equipment. Its OM3 multimode construction and LC connector compatibility allow consistent results when measuring loss, continuity, and duplex transmission on standard multimode networks.

Suitable for

• Testing and troubleshooting LC-terminated multimode fiber links
• Verifying transmission capability and continuity of OM3 fibers
• Validating full-duplex optical ports in networking equipment
• Laboratory measurements and maintenance checks on multimode installations

How to use

Insert the LC connector of the loopback adapter into the LC port to be tested so that the transmit and receive paths are looped back. Run your optical test procedure or diagnostic tool to measure loss, continuity, or duplex functionality. Remove the adapter after testing and store it in a protective case to prevent contamination of the fiber endfaces.

Recommendations

Keep the LC endfaces clean and free of dust; use appropriate fiber cleaning tools before connecting. Avoid bending the fiber beyond its minimum bend radius and store the adapter in a dry, dust-free environment when not in use.
