The FC connector is a fiber-optic connector with a threaded body, which was designed for use in high-vibration environments. It is commonly used with both single-mode optical fiber and polarization-maintaining optical fiber. FC connectors are used in datacom, telecommunications, measurement equipment, and single-mode lasers.

2021年12月9日 · You may have heard of SC UPC, LC UPC, SC APC, LC APC, FC APC, FC UPC? What do they mean? The LC, SC, and FC indicate the different structures of fiber connector types, whereas the UPC and APC indicate different polishing shapes of …

实验室常见的光纤接头主要有FC/PC和 FC/APC两种。这里的FC指的是ferrule contactor,是钢制的金属套筒（光纤连接器与电缆连接器的一个区别就是金属质地，电缆连接器多采用铜质，为的是导电性好；而光纤连接器没有导电一说，另外铜既软又贵还生锈）。

2023年11月22日 · UPC stands for Ultra Physical Contact. In fact, it is an enhanced version of the PC fiber connector. Based on the convex face properties of the PC, the connector utilizes an extended polishing method to create a better surface finish on the fiber.

2019年6月13日 · Along with standard ends, fiber connectors can be made with UPC (Ultra Physical Contact) or APC (Angled Physical Contact) specifications. A cable with one of these specs will have the suffix “-UPC” or “-APC” added onto its name.

2020年3月29日 · 实验室常见的光纤接头主要有FC/PC和 FC/APC两种。 这里的FC指的是ferrule contactor，是钢制的金属套筒。 PC指的是紧密接触physical contact，同样是紧密接触，根据回波损耗的不同，连接器分为PC， UPC和APC。 UPC指的是ultra physical contact，PC和UPC工业标准规定的回波损耗分别为-35dB， -50dB (回波损耗是指有多少比例的光又被连接器的端面反 …

2008年2月18日 · To reduce the back reflection of a connector, it can be polished to SPC (Super Physical Contact) polish or UPC (Ultra Physical Contact) polish. Industry standard is a minimum of –40dB for SPC back reflection measurement and –50dB for UPC back reflection measurement.

The combination of a Ceramic ferrule with precision Nickel plated Brass housing provides consistent long-term mechanical and optical performance. The FC connector is available in single mode UPC and APC versions as well as multimode.
