Product information

Description

The EFB Elektronik fibre optic adapter with SC/ST connector types and uncoated contacts is designed to provide reliable optical connections in communication and data transmission systems. Its blue housing enables quick visual identification within patch panels and distribution frames. The adapter maintains precise alignment between SC and ST ferrules to preserve signal integrity and to minimize insertion loss in singlemode and multimode links where compatible.

Advantages

The adapter offers stable mechanical alignment between different connector styles, reducing back reflections and maintaining consistent optical performance. Its uncoated contacts are compatible with standard ferrule geometries and simplify mating of SC and ST connectors. The compact design fits standard adapter panels and minimizes space usage while providing a repeatable, low-loss junction point for fiber runs.

Suitable for

Patch panels and distribution frames in telecommunications racks
Interconnection of SC and ST terminated fiber cables
Laboratory setups and test benches for fiber link measurements
Fiber optic installations in data centres and network closets

Key specifications

Connector types: SC to ST adapter
Contact finish: uncoated ferrule contacts
Color: blue for easy identification
Form factor: compact adapter suitable for standard panels
Application: designed for optical signal coupling with low insertion loss

How to use

Insert an SC-terminated cable plug into the SC side of the adapter and an ST-terminated plug into the ST side, ensuring both connectors are fully seated and the latch or bayonet coupling engages correctly. Verify physical alignment visually and, where required, confirm optical continuity and insertion loss using appropriate test equipment. When disconnecting, release the bayonet or push-pull mechanism before removing the connector to avoid ferrule damage.

Usage recommendations

Handle the adapter and connected fibers with care to avoid contamination of ferrule endfaces; use dust caps when ports are unused and clean connector endfaces with approved fiber cleaning tools before mating. For consistent performance, verify connector cleanliness and inspect for physical damage prior to installation.
