These connectors are identifiable by their green color.
Apc fiber connector color.
However the advent of metallic connectors like the fc and st made connector color coding difficult so colored strain relief boots were often used.
An apc polished connector has an industry standard minimum f 60db orl measurement.
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.

An apc connector has an 8ยบ angle cut into the ferrule.
Upc connectors are polished with no angle.
As you can see in the.
Fiber optic lc connector with apc upc polishing type.
Fiber optic cables are available in a wide range that varies according to use length diameter etc.
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.
Upc connectors are easily identified by their blue color on the connector boot.
Fiber optics color standards.
Introduction to different connector types.
Since the earliest days of fiber optics orange black or gray was multimode and yellow singlemode.
Upc connectors are blue while apc connectors are green.
The major physical difference between apc and upc connector is the endface geometry.
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.
Each connector package includes a fiber connector cap and plastic boot.
These connectors also feature a low 0 25 db connector to connector typical loss.
Apc fiber ends have low back reflection even when disconnected.
In general the higher the return loss the better the performance of the mating of two connectors.

Apc connectors feature a fiber endface that is polished at an eight degree angle.
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.
The following figure picture shows the differences mentioned above intuitively.
Another more obvious difference is color.

Besides the fiber end face another more obvious difference is the color.
Generally upc connectors are blue while apc connectors are green.
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.
