STARTECH LC/UPC Duplex Keystone Coupler gender changer

SKU CH-YE43-HFWXY

Connects two LC/UPC duplex fibre cables in a keystone patch panel with a ceramic-lined sleeve and metal tabs

  • Duplex design enables two-fibre connections in one keystone
  • LC/UPC polish delivers low-insertion-loss performance for single-mode fibre
  • Ceramic-lined sleeve ensures precise ferrule alignment and durability
  • Metal tabs provide secure snap-in mounting in standard keystone panels
  • ABS housing offers impact-resistant protection for installed fibres

LC/UPC Duplex Keystone Coupler

This StarTech LC/UPC duplex keystone coupler provides a female-to-female connection for two LC fibre-optic cables. It is designed for patch-panel or wall-plate installations where a secure, low-loss link between duplex single-mode or multimode fibres is required. The keystone form factor snaps into standard cut-outs for quick deployment. Network installers and IT technicians use it to extend or cross-connect fibre runs in data-centre and enterprise environments.

Thermals Noise and Power

As a passive mechanical coupler the unit generates no heat, produces no audible noise and draws zero electrical power. The ABS housing and ceramic-lined inner sleeve maintain alignment without active cooling. Metal retention tabs ensure a firm seat in the keystone opening, eliminating vibration or movement that could degrade signal quality. Operation is entirely silent and thermally neutral in any cabinet or enclosure.

Bundled Accessories and Software

No accessories, cables, tools or software are included with the coupler. The package contains only the keystone jack itself, so installers must supply compatible LC patch cords, a keystone punch-down or snap-in tool, and any patch panel or faceplate separately. There is no configuration utility or driver required; the coupler is purely a physical layer component that works immediately once seated and cabled.

Questions about this item

How do I install the LC/UPC duplex keystone coupler into a patch panel, and what step is often missed?

Snap the coupler into a standard keystone cut-out until the metal tabs click; the step often missed is fully seating both tabs so the ceramic-lined sleeves align precisely with the patch cords.

What maintenance or replacement will the coupler need over time?

The ceramic-lined inner sleeves do not degrade, but the LC ferrules on connected patch cords should be inspected and cleaned with a fibre scope and lint-free wipes whenever loss increases.

What is the first limit that appears under sustained use?

Insertion loss remains stable; the practical limit is repeated mating cycles on the patch-cord ferrules, which can wear the ceramic end-faces before the coupler itself shows any change.
