## Long description

The VALUE 21.99.0620 fibre optic adapter ST is designed to provide reliable single‑mode or multimode connectivity between ST‑terminated fibre cables. Housed in a durable steel body with a grey finish, the adapter is supplied as a single unit and intended for in‑rack, panel or wall plate mounting where a compact and stable mechanical interface is required. The product supports simple insertion and alignment of ST plugs to maintain signal integrity in networking and telecommunications environments.
Advantages
The steel housing offers mechanical robustness and protects the ferrule alignment under regular mating cycles. The standard ST interface ensures compatibility with a wide range of fibre patch cables and equipment. The neutral grey finish is suitable for professional installations and helps visually integrate the adapter into patch panels and outlets. Sold individually, the adapter allows selective replacement or expansion without the need to purchase multi‑packs.
Suitable for
 Connecting ST fibre patch cables in local area networks (LAN)
 Panel, rack or wall plate mounting in server rooms and communication cabinets
 Repairing or extending existing ST fibre links
 Use in educational, industrial or office networking environments
Key specifications
 Connector type: ST female to ST female
 Housing material: steel
 Finish/color: grey
 Packaging: single unit
 Intended use: fibre optic patching and coupler applications
How to use
Install the adapter into the appropriate panel cutout or wall plate opening and secure it according to the mounting frame or panel instructions. Align the ST plug by inserting the bayonet ferrule into the adapter and twist to lock; ensure connectors are clean and free of dust before mating to prevent signal loss. For removal, depress the locking mechanism on the ST plug and pull straight out to avoid lateral stress on the fibre. Handle with care to maintain ferrule alignment and avoid sharp bends in the connected fibre cables.
Usage recommendations
Use optical cleaning tools or lint‑free wipes with appropriate cleaning fluid to remove contamination from connector endfaces before connecting. Store unused adapters and connectors with protective caps in a dry, dust‑free environment. For installations requiring specific optical losses or certifications, verify system performance with an optical loss test set or power meter after assembly.
