ST simplex single-mode fiber coupler

The Cables To Go ST-ST simplex single-mode fiber coupler joins two ST-terminated fibers in a straight-through metal adapter. It is intended for installers and network technicians who need a reliable in-line connection for single-mode patch cords or distribution cables.

Simplex single-mode capacity and headroom

The coupler passes a single optical path per unit, matching the simplex configuration of the connected patch cords. It supports standard single-mode wavelengths and insertion-loss budgets; performance is limited by the quality of the mating ferrules and the cleanliness of the end faces rather than by the adapter itself.

Metal housing and ST connector implications

A metal body provides mechanical durability and shields the ceramic sleeves from impact during rack or wall-plate mounting. Dual ST female ports accept standard bayonet connectors, allowing quick mating and unmating without tools while maintaining alignment for repeatable low-loss connections.

Questions about this item

Will the ST simplex single-mode coupler fit alongside legacy ST patch cords already terminated in my rack?

Yes — the adapter presents two ST female ports, so existing ST-terminated cables plug straight in without gender changers.

How can I confirm the link is passing light after I connect the two ST cables?

Check the link LEDs on the connected transceivers or run an optical power meter through the mated pair to verify continuity.

Does the package include the ST patch cords or only the metal-bodied coupler itself?

Only the coupler is supplied; ST single-mode patch cords must be purchased separately.
