Apc Fiber Connector Color

Besides the fiber end face another more obvious difference is the color.

Apc fiber connector color. An apc polished connector has an industry standard minimum f 60db orl measurement. Fiber optic lc connector with apc upc polishing type. Apc fiber ends have low back reflection even when disconnected. The major physical difference between apc and upc connector is the endface geometry.

The generally accepted color code for connector bodies and or boots is beige for multimode fiber blue for single mode fiber and green for apc connectors. Upc connectors are blue while apc connectors are green. These connectors also feature a low 0 25 db connector to connector typical loss. Upc connectors are polished with no angle.

The following figure picture shows the differences mentioned above intuitively. However significant insertion loss can result when mating to different styles and because of this we recommend that fc apc connectors be mated only with other fc apc connectors. Cable jacket colors make it faster and simpler to pinpoint which. An apc connector has an 8º angle cut into the ferrule.

Fiber optic cables are available in a wide range that varies according to use length diameter etc. Upc connectors are not exactly flat however. Giving each one a specific color allows better and faster recognition of the cable in use and avoids issues due to bad connections or confusions. Lc apc single mode 9 125um fiber optic connector in green color lc upc single mode 9 125um fiber optic connector in blue color.

They have a slight curvature for better core alignment. To put it simply pc upc and apc refer to the polish styles of the ferrules inside the fiber optic connectors just as the following figure shows the ferrule is the housing for the exposed end of a fiber designed to be connected to another fiber or into a transmitter or receiver. Since the earliest days of fiber optics orange black or gray was multimode and yellow singlemode. In general the higher the return loss the better the performance of the mating of two connectors.

These connectors are identifiable by their green color. Generally upc connectors are blue while apc connectors are green. Lc upc multi mode om3 om4 fiber optic connector in aqua color. Lc upc multi mode 62 5 125um or 50 125um fiber optic connector in gray color.

Upc connectors are easily identified by their blue color on the connector boot. Fiber optics color standards. However the advent of metallic connectors like the fc and st made connector color coding difficult so colored strain relief boots were often used. As you can see in the.

Sc apc connector is commonly used in applications that are much more sensitive to return loss and requires for high precision signal such as fttx fiber to the x video delivery through rf signal wdm wavelength division multiplexing applications and analogue equipment like cctv. Introduction to different connector types.
