Product information

Description

Lightwin ST‑ST Duplex Multimode LKUP DST‑DST MM VM is a fiber optic coupling designed to provide a reliable duplex connection between two ST multimode connectors. Intended for panel or chassis installation, the coupling ensures correct alignment and easy insertion of ST plugs for multimode fiber links used in local networks, industrial connections, and equipment interconnects.

Advantages

The Lightwin ST‑ST duplex coupling offers stable optical alignment, simple ST plug insertion and removal, and compact panel/chassis mounting compatible with standard cutouts. It is built for multimode environments and reduces signal loss at the connection point while maintaining consistent physical interface geometry.

Suitable for

  • Local area network multimode fiber links
  • Industrial fiber optic connections and control systems
  • Interconnects between networking equipment or patch panels using ST multimode terminations

Key specifications

  • Brand: Lightwin
  • Model / MPN: LKUP DST‑DST MM VM
  • Connector type: ST to ST (duplex)
  • Fiber type: Multimode
  • Mounting: Panel / chassis
  • EAN: 9120058270390

How to use

Mount the coupling into the appropriate panel or chassis cutout. Insert ST plugs from each multimode fiber cable into the two ST ports until they engage. Ensure connectors are clean and free of dust before mating to minimize insertion loss. For removal, depress the ST bayonet and withdraw the plug with a straight pull.

Usage recommendations

For optimal performance, clean connector end-faces before each connection and avoid excessive bending of multimode fiber near the coupling. Use in environments that match the multimode fiber specifications and ensure compatible ST terminations on connected cables and equipment.
