Glasvezeladapter ST-ST simplex ACT EA2004

The ACT Fiber optic adapter ST-ST simplex EA2004 is a single-mode inline coupler designed to join two ST connector-terminated fiber optic cables. Finished in a red housing, this adapter supports simplex connections and provides a compact interface to maintain optical alignment between mating ST plugs. It is supplied as an individual unit for straightforward replacement or extension of single-mode links in patch panels, wall outlets and field installations.

Advantages

This ST-ST simplex adapter offers accurate mechanical alignment through precision ceramic sleeves to ensure low insertion loss and consistent optical performance. Its metal-backed housing provides durability while the keyed bayonet ST interface secures connectors against rotation and accidental disconnection. The compact footprint and standardized ST interface simplify installation and compatibility with existing fiber cabling infrastructure.

How to use

Insert the ST connector of the incoming fiber into one end of the adapter until the bayonet latch engages, then insert the mating ST connector of the outgoing fiber into the opposite end. Verify that both connectors are fully seated and latched. For panel or faceplate mounting, position the adapter into the designated cutout or holder and secure according to the panel design. Before making live connections, inspect connector endfaces and clean with appropriate fiber cleaning tools to prevent increased insertion loss or signal degradation.

Recommendations

Use with single-mode ST-terminated cables only; avoid using the adapter in environments where moisture or particulate contamination may reach the connector interface without appropriate protection. Regularly inspect and clean endfaces, and handle connectors by the boot or body to prevent contact with the ferrule endface.
