Apc Fiber Connector Color

Cable jacket colors make it faster and simpler to pinpoint which.

Apc fiber connector color. Lc apc single mode 9 125um fiber optic connector in green color lc upc single mode 9 125um fiber optic connector in blue color. These connectors also feature a low 0 25 db connector to connector typical loss. In general the higher the return loss the better the performance of the mating of two connectors. Fiber optics color standards.

Introduction to different connector types. 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. However the advent of metallic connectors like the fc and st made connector color coding difficult so colored strain relief boots were often used. Since the earliest days of fiber optics orange black or gray was multimode and yellow singlemode.

As you can see in the. Another more obvious difference is color. 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. Upc connectors are blue while apc connectors are green.

Upc connectors are polished with no angle. 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. The major physical difference between apc and upc connector is the endface geometry. The following figure picture shows the differences mentioned above intuitively.

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. Fiber optic cables are available in a wide range that varies according to use length diameter etc. Besides the fiber end face another more obvious difference is the color. Fiber optic lc connector with apc upc polishing type.

They have a slight curvature for better core alignment. Apc fiber ends have low back reflection even when disconnected. Each connector package includes a fiber connector cap and plastic boot. An apc connector has an 8º angle cut into the ferrule.

These connectors are identifiable by their green color. Apc connectors feature a fiber endface that is polished at an eight degree angle. Upc connectors are easily identified by their blue color on the connector boot. Lc upc multi mode 62 5 125um or 50 125um fiber optic connector in gray color.

Lc upc multi mode om3 om4 fiber optic connector in aqua color. Generally upc connectors are blue while apc connectors are green.
