ST Optical Fibre Connector

The ST connector has been the main stay of the optical fibre connectors for many years. It can be found in almost every communications room world wide, but used mainly in Data communications systems. Its simple to use bayonet locking system reduces the risks of accidental disconnection of fibre connections.
 
The Optronics ST Optical Fibre connector is comprised of a nickel plated brass body and a ceramic ferrule/spring/crimp barrel assembly plus a crimp over sleeve and rubber boot. These connectors are suitable for, 900µm and 2.4—3mm cables. The connector is precision made and manufactured to demanding specifications.
 
The combination of a ceramic ferrule and a precision metal housing provides consistent long-term mechanical and optical performance.
 
Optronics has 14 years experience in manufacturing fibre optic Connectors and cable assemblies. From Biconic and SMA through ST, SC and MU to today’s Small Form Factor connectors like the LC, MT-RJ or SC-DC. If you have a fibre network, no matter what the technology, Optronics can offer you a solution to your problem.
 
Optronics has full ISO9001 on all of its manufacturing facilities, so you can be confident you are using the very best in Cable, Connectors AND manufacturing.

Description

The ST connector is the most popular connector used today. It can be seen in every area of the communications environment, from a telecoms distribution room to a local area network closet the ST has set the standard for optical fibre connectors.

The Optronics ST connectors are manufactured using the best quality components. The connectors exceeds all areas of the standards covering optical fibre connectors.
