FAQ

What is a fiber optic keystone coupler used for?

It allows you to pass fiber connections through a standard keystone wall plate or patch panel, making installations cleaner and more modular.

Can I use these couplers for both singlemode and multimode?

Yes, this product line includes models for singlemode (UPC & APC) and multimode (OM1 through OM5). Just make sure to match the correct coupler to your fiber type.

Do these keystone couplers support duplex and simplex connections?

Yes. LC couplers are typically duplex, SC couplers are simplex, and MTP couplers support high-density trunking using male-to-female connections.

Are these compatible with any keystone wall plate?

These couplers are designed to fit any standard keystone opening, including wall plates, surface boxes, LGX adapter panels, and rack-mount patch panels.

Is there a difference between APC and UPC couplers?

Yes. APC (Angled Physical Contact) couplers are used for applications requiring low back reflection, while UPC (Ultra Physical Contact) is more common in general networking. Make sure to match the connector polish type to your cables.
