Advantages

The duplex ST/SC adapter provides accurate coupling and alignment of ST and SC connectors through its internal metal ferrule, ensuring consistent multi-mode performance. Its flange and screw-compatible design simplifies installation into patch panels and distribution frames. The metal sleeve increases mechanical durability, while the compact bush form factor allows dense panel layouts.

How to use
