Product information

Description

The EFB Elektronik 53202.3 is a metallic ST simplex multimode fibre optic adapter designed to provide a secure mechanical connection between ST-terminated multimode optical fibres. With compact dimensions (9.6 mm × 30.1 mm × 9.6 mm) and a metal housing, this adapter is intended for reliable use in multimode fibre patching and panel installations where ST connectors are required.

Advantages

The metal body offers mechanical durability and stable alignment of ST ferrules, reducing insertion loss and ensuring consistent optical contact. Its compact size makes it suitable for high-density mounting in patch panels or bulkhead applications. The adapter is compatible with standard multimode ST connectors and follows common mechanical tolerances for fibre optic connectivity.

Suitable for

  • Multimode fibre patch panels
  • Bulkhead and faceplate installations
  • Equipment and enclosure front panels requiring ST simplex connections

Key specifications

  • Brand: EFB Elektronik
  • Manufacturer part number (MPN): 53202.3
  • EAN: 4049759023317
  • Connector type: ST simplex
  • Fibre type: Multimode
  • Material: Metal housing
  • Dimensions (W × D × H): 9.6 mm × 30.1 mm × 9.6 mm

How to use

Install the adapter into the panel cut-out or bulkhead designed for ST simplex adapters, securing it according to the panel / chassis mounting method. Insert ST-terminated multimode fibre connectors into each end of the adapter until they click or seat firmly, ensuring correct ferrule alignment. For removal, withdraw the connector straight out to avoid disturbing the mating ferrule.

Usage recommendations

Use with standard multimode ST connectors and clean ferrule endfaces before mating to minimise insertion loss and back reflection. Avoid excessive mechanical stress on the adapter or connected fibres and ensure panels are mounted to prevent vibration or strain that could affect optical alignment.
