UPC type fiber optic connector is a common connector type in the field of fiber optic communications, this article will analyze around its characteristics and use.
UPC type fiber optic connector features
1. The shape of the end face UPC connector pin end face has been optimized to make its surface more smooth, dome-shaped. This design allows the fiber optic end face to achieve closer contact when docking, thus reducing the impact of Fresnel reflection.
2. High return loss compared with the PC type, UPC provides a higher return loss, usually can reach more than 50dB, which means that it can better suppress the impact of unwanted reflected light on the system performance.
3. Low insertion loss Due to its precision manufacturing process and high-quality polishing technology, UPC connectors are usually able to achieve low insertion loss, generally less than 0.3dB, which helps to maintain signal strength and integrity.
Scenarios for UPC type fiber optic connectors
In view of the above characteristics, UPC connectors are suitable for a variety of application scenarios, such as Ethernet network equipment, ODF (Optical Distribution Frame) fiber optic distribution frames, media converters and fiber optic switches, etc., which often require stable and high-quality optical signal transmission. There are also digital TV and telephone systems, which have high requirements for signal quality, and the high return loss value of UPC connectors helps to ensure the accuracy and stability of data transmission.
It also includes applications that require high signal quality. In carrier-grade applications, such as data transmission links within data centers or backbone lines in enterprise-class networks, UPC connectors are widely used because of their superior performance. However, in specific situations, such as analog optical communication systems such as CATV or WDM systems using Raman fiber amplifiers, where a higher level of return loss control may be required, an APC connector may be chosen over a UPC.This is because although UPCs already provide excellent return loss performance, under extreme conditions, such as the presence of severe endface contamination, the additional return-loss advantage becomes particularly important.
