FC/UPC to FC/APC Fiber Patch Cords with Single-Mode 9/125 Duplex Cables

These high speed single-mode 9/125µm duplex fiber optic patch cables are terminated with FC/UPC fiber optic connectors on one end and FC/APC fiber optic connectors on the other end (FC/UPC-FC/APC). Ferrule Connectors ("FC") utilize a screw-on coupling type to be used in high-vibration environments and are commonly used for datacom, telecom, measurement equipment and single-mode lasers. They are slowly becoming less common in today's expanding fiber optic world.

Our extensive range of fiber patch cables are terminated with state-of-the-art connectors, which are available in any combination of ST, SC, FC, and LC with PC, UPC or APC polish types to meet your standard or custom configurations. Our fiber jumpers have been geometrically inspected with interferometers and tested with automated insertion loss and reflection test equipment to ensure exceptional performance.

To help complete your fiber optic network installation, we offer end-to-end solutions with our wide range of products that include fiber optic enclosures, fiber channel testers, splice trays and other fiber optic accessories.

Additional Information

Your patch cord selection is important to the type of fiber optic network you are working on. Some are ideal for single mode, while others might be the right for a Multimode installation. Another factor to consider is polish type when using single mode cables.

While you patch cord choice is important, it is only one piece of the fiber optic network to choose from. Take a look at what's available in these other key product categories:

Connector Type Abbreviations:

SC - a snap-in style connector. Known for its excellent performance. Referred to as Subscriber Connectors, Square Connectors or Standard Connectors.

ST - a very popular choice connector for Multimode networks. Also referred to as Straight Tip connectors, they utilize a bayonet-style coupling type, enabling a simple twist-on and twist-off installation.

FC - was at one time the most popular single mode connector type, but is now typically being replaced by SC and LC connectors. Also known as Ferrule Connectors, they utilize a screw-on coupling type to be used in high-vibration environments and are commonly used for datacom, telecom, measurement equipment and single-mode lasers.

LC - a small form factor connector—measuring half the size of an SC connector. This is a popular choice for single mode cables. Also referred to as Lucent Connectors, Little Connectors or Local Connectors, these snap-in connectors are typically used for high density connections and are compatible with plug-and-play devices such as SFP modules and XFP transceivers.


Polish Type Abbreviations:
Note: The polish type affects the amount of back reflection, also known as reflectance.

PC - Physical Contact. Polished to create a slight dome at the end of the ferrule that helps to maximize the signal being transmitted.

UPC - Ultra Physical Contact. More extensive polishing than the PC type, a greater dome shape is created that further help to maximize the signal being transmitted.

APC - Angled Physical Contact. Polished at an angle rather than a dome shape. This is the most efficient polish type.
