FAQ

What is the difference between an ST SX adapter and SC or LC adapters?
The ST adapter uses a bayonet-style twist-lock mechanism, unlike SC’s push-pull and LC’s small-form-factor design. ST is often used in older or industrial fiber systems.
SX stands for simplex, meaning it supports a single fiber connection—one transmit or one receive line.
Adapters without flanges are ideal for installations in compact environments or inside custom modules where space and mounting constraints exist.
Yes. The metal housing and bayonet-locking mechanism of the ST adapter offer good mechanical stability, suitable for such conditions.
