FAQ

What is the difference between the UPC and APC couplers?

The UPC (Ultra Physical Contact) couplers provide a flat polishing of the fiber ends, while APC (Angled Physical Contact) couplers have an angled polish that minimizes back reflection. APC couplers are typically used in applications where low back reflection is critical, such as long-distance communication systems.

Do these couplers work with both singlemode and multimode fiber?

Yes, we offer universal couplers that are compatible with both singlemode and multimode fibers, allowing you to seamlessly integrate into mixed-fiber environments.

Can I customize the length or strand count of the couplers?

These couplers are stock items, which means they do not offer custom lengths or strand counts. However, we do offer other customizable products elsewhere on our site to meet specific needs.

How do I install the singlemode fiber optic couplers?

The installation of these couplers is easy, especially with the flange and mounting options available. Simply attach the coupler to the corresponding fiber optic connector and ensure that it is securely positioned for optimal signal transmission. For models with dust cover doors, ensure that the doors are properly closed during installation to protect the fibers.

What is the lead time for shipping?

These couplers typically ship within 24 business hours from the time of order, allowing you to receive your products quickly and efficiently.
