Lc upc multi mode 62 5 125um or 50 125um fiber optic connector in gray color.
Apc fiber connector color.
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.
Fiber optics color standards.
The major physical difference between apc and upc connector is the endface geometry.
These connectors also feature a low 0 25 db connector to connector typical loss.
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.
They have a slight curvature for better core alignment.
Generally upc connectors are blue while apc connectors are green.
Since the earliest days of fiber optics orange black or gray was multimode and yellow singlemode.
Upc connectors are easily identified by their blue color on the connector boot.
An apc connector has an 8ยบ angle cut into the ferrule.
An apc polished connector has an industry standard minimum f 60db orl measurement.

Introduction to different connector types.
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.
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.
In general the higher the return loss the better the performance of the mating of two connectors.
Apc fiber ends have low back reflection even when disconnected.
However the advent of metallic connectors like the fc and st made connector color coding difficult so colored strain relief boots were often used.
Another more obvious difference is color.
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.
Apc connectors feature a fiber endface that is polished at an eight degree angle.
Each connector package includes a fiber connector cap and plastic boot.
As you can see in the.
Upc connectors are not exactly flat however.
