Fiber optic adapter Telegärtner ST/ST simplex coupling, metal body, 21.17.0605

Telegärtner ST/ST simplex fiber optic adapter with a metal body is a compact coupling for connecting two ST simplex connectors. Designed to provide stable mechanical alignment, the adapter suits both multimode and singlemode ST terminations and is intended for installation in patch panels, wall plates and fiber extension links. Its metal housing offers mechanical robustness and consistent mating performance while enabling uncomplicated insertion and removal for routine maintenance.

Advantages

The metal body ensures durable protection against mechanical stress and maintains precise fiber alignment to reduce insertion loss. Its simplex ST interface provides a reliable, keyed connection that minimises rotational misalignment. The compact, standardized form factor allows integration into common fiber distribution hardware and supports straightforward field handling and replacement.

Suitable for

• Joining two ST simplex fiber connectors in patch panels
• Fiber wall plates and outlet installations
• Short fiber extension links and equipment interconnects
• Environments requiring robust metal housings and repeatable connections

Key specifications

• Connector type: ST simplex coupling
• Housing material: metal for improved durability
• Compatibility: multimode and singlemode ST terminations
• Form factor: compact, suitable for patch panels and wall plates
• Function: fixed mechanical alignment for low-loss connections

How to use

Install the adapter into the chosen panel or plate opening if required, ensuring the coupling is seated securely. Align and insert each ST connector into the respective adapter interface until the keyed bayonet engagement is felt; confirm secure seating by a light tug test. For removal, press the release mechanism on the ST connector and withdraw straight out to avoid fiber bend stress. Perform end-face inspection and cleaning before mating to maintain optimal optical performance.

Usage recommendations

Use approved fiber inspection and cleaning tools before each connection and follow standard fiber handling practices: avoid excessive bending, protect exposed ends, and keep dust caps in place when connectors are not mated. Select this metal-body ST/ST simplex adapter where mechanical robustness and repeatable alignment are priorities.
