Fiber optic cables are available in a wide range that varies according to use length diameter etc.
Apc fiber connector color.
As you can see in the.
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.
Since the earliest days of fiber optics orange black or gray was multimode and yellow singlemode.
Fiber optics color standards.
Besides the fiber end face another more obvious difference is the color.
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.
An apc polished connector has an industry standard minimum f 60db orl measurement.
An apc connector has an 8ยบ angle cut into the ferrule.
Upc connectors are polished with no angle.
These connectors are identifiable by their green color.
Fiber optic lc connector with apc upc polishing type.
Upc connectors are blue while apc connectors are green.
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.
Apc fiber ends have low back reflection even when disconnected.
The major physical difference between apc and upc connector is the endface geometry.
Cable jacket colors make it faster and simpler to pinpoint which.
Each connector package includes a fiber connector cap and plastic boot.
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.
In general the higher the return loss the better the performance of the mating of two connectors.
Upc connectors are not exactly flat however.
Lc upc multi mode 62 5 125um or 50 125um fiber optic connector in gray color.
Another more obvious difference is color.
Introduction to different connector types.
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.
These connectors also feature a low 0 25 db connector to connector typical loss.
Generally upc connectors are blue while apc connectors are green.
