Optický loopback adaptér DeLOCK 86920 SC UPC Singlemode modrý

The DeLOCK Optical Fiber Loopback Adapter SC UPC (model 86920) is a singlemode loopback connector designed for testing and troubleshooting fiber optic links. It uses an SC UPC interface for full-duplex transmission and is color-coded blue to indicate singlemode compatibility. The adapter allows measurement of transmission capability and verification of optical fiber connections in network equipment and test setups.

Advantages

The loopback adapter provides a compact and robust solution for returning optical signals to the transmitting device without additional cabling. Its SC UPC connector ensures stable mating and low back-reflection suitable for singlemode testing. The blue housing enables quick identification of singlemode components in mixed installations.

Suitable for

• Testing and troubleshooting singlemode fiber links
• Verifying transmission capability of optical fibers
• Loopback tests in network equipment and transceivers with SC UPC ports
• Lab and field diagnostics of fiber optic networks

How to use

Insert the SC UPC connector of the loopback adapter into the SC port of the device or transceiver to be tested. Ensure a clean connector endface before connection to avoid measurement errors. Once connected, perform loopback or optical power measurements with the appropriate test equipment; the adapter returns the transmitted signal to the receiver, enabling verification of link behavior.

Recommendations

Handle and store the loopback adapter in a clean, dust-free environment. Clean connector endfaces with appropriate fiber cleaning tools before use. Use the adapter only with compatible SC UPC singlemode ports; avoid exposing the connector to physical stress or contaminants to maintain measurement accuracy.
