Lightwin Dead Zone Eliminator DZE SM FC-LC — Vorlauffaserbox accessory for multimode and singlemode fibers

Lightwin Dead Zone Eliminator DZE SM FC-LC is an accessory for the Vorlauffaserbox designed to provide interface compatibility between FC and LC connectors on both multimode and singlemode fiber links. The accessory addresses dead-zone issues that can appear during fiber testing and patching by adapting connector types and enabling reliable connection between test equipment and fiber cabling in data centers and telecom environments.

Advantages

The device supports both multimode and singlemode fiber connections, allowing a single accessory to be used across different fiber types and reducing the need to carry multiple adapters. Its FC-to-LC interface compatibility simplifies connecting FC-equipped test equipment to LC-terminated fibers and helps to minimise measurement dead zones during testing and verification. The compact form factor integrates with the Vorlauffaserbox workflow and is intended for quick installation and removal in field or rack environments.

Suitable for

• Technicians performing optical time-domain reflectometer (OTDR) testing where dead-zone reduction is required
• Field engineers connecting FC test probes to LC-terminated patch panels or trunk cables
• Data center and telecom maintenance tasks involving both multimode and singlemode fibers
• Temporary or permanent patching where connector adaptation from FC to LC is needed

When it may not be suitable

The accessory is intended primarily for connector adaptation and dead-zone management and does not replace components designed for permanent fusion splicing or in-line optical amplification. It is not a diagnostic instrument on its own; successful use requires compatible test equipment and properly terminated fibers. Environments that require dust-tight or IP-rated sealed connections for long-term outdoor deployment may need more ruggedized solutions.

Key specifications

• Connector compatibility: FC to LC interface adaptation
• Fiber types supported: multimode and singlemode
• Designed for integration with Vorlauffaserbox systems

How to use

Insert the Dead Zone Eliminator into the appropriate port of the Vorlauffaserbox or connect it between the FC-equipped test instrument and the LC-terminated fiber under test. Ensure connectors are clean and properly aligned before making the connection to minimise insertion loss and contamination. Use the accessory while performing OTDR or other fibre characterization tests to reduce measurement dead zones; remove or keep in place as required for patching or temporary adaptation tasks.

What to consider before purchase

• Confirm that your test equipment uses FC connectors and that the field cabling uses LC terminations
• Verify whether you require support for multimode, singlemode, or both fiber types
• Consider connector cleanliness practices and whether protective dust caps or storage are needed when not in use

Usage recommendations

Maintain connector endface cleanliness and inspect endfaces before each connection. Use the accessory as part of established testing procedures to reduce dead-zone effects and follow manufacturer guidance for the Vorlauffaserbox and your OTDR or test equipment.
