These connectors also feature a low 0 25 db connector to connector typical loss.
Apc fiber connector color.
Besides the fiber end face another more obvious difference is the color.
In general the higher the return loss the better the performance of the mating of two connectors.
An apc connector has an 8ยบ angle cut into the ferrule.
Upc connectors are blue while apc connectors are green.
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.
Introduction to different connector types.
Fiber optics color standards.
Fiber optic cables are available in a wide range that varies according to use length diameter etc.
The following figure picture shows the differences mentioned above intuitively.
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.
These connectors are identifiable by their green color.
Upc connectors are polished with no angle.
As you can see in the.
Upc connectors are easily identified by their blue color on the connector boot.
Apc connectors feature a fiber endface that is polished at an eight degree angle.
Apc fiber ends have low back reflection even when disconnected.
Fiber optic lc connector with apc upc polishing type.
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.
Another more obvious difference is color.
Generally upc connectors are blue while apc connectors are green.
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 not exactly flat however.
Since the earliest days of fiber optics orange black or gray was multimode and yellow singlemode.
Each connector package includes a fiber connector cap and plastic boot.
They have a slight curvature for better core alignment.
An apc polished connector has an industry standard minimum f 60db orl measurement.

Cable jacket colors make it faster and simpler to pinpoint which.
The major physical difference between apc and upc connector is the endface geometry.
