What about Single Model and Multi Model Cable? What is the difference between multimode and single mode fiber?

Differences in Polishing Processes for Different Ferrule Diameters？ Large Diameter Ferrule Face Grinding Process（FC/SC/ST-PC） Small Diameter Ferrule Face Grinding Process（LC-PC）

How to Solve the Problem of End-face Polishing？ 1、How to remove scratches? Why the scratches are produced？ (1) The time of medium polishing is too short； (2) Residual abrasive debris on the polished front face. 2、How to reduce scratches? (1) Increase the grinding time of medium grinding; (2) Clean the grinding end face; (3) Glue ring

Differences between the 3 Common End-face Types 1. Why should fiber optic end-faces be polished? 2、Insertion loss and return loss of different end-faces 3、Specific applications of the three end-face types

Under the background of the rapid development of information technology such as digital economy, smart city and big data processing, the optoelectronics industry has entered into the fast lane, especially in recent years, the demand for all kinds of fiber optic sensing and Internet of Things applications has also shown explosive growth, which has made the core value of PM optical fiber more and more prominent. With the improvement of basic technology and manufacturing process of PM fiber, the fiber has become a functional "carrier", combined with future applications, PM fiber technology will show functionality, matching and robustness.

What’s the Fast and Slow Axis？How to Align the PM Fiber？What is Beat Length?What is extinction ratio? How to align the "panda's eye"?

What’s Polarization Maintaining Fiber？How to manufacture Polarization Maintaining fiber？

There are many types of polarization maintaining fibers, which can be divided into high birefringence optical fibers (birefringence coefficient B~10-4) and low birefringence optical fibers (B~10-7; B~10-9) according to the size of birefringence.

Now optical fiber is widely used in our life, but due to the ordinary optical fiber has no way to manufacture into completely symmetrical optical fiber, and optical fiber in the actual application will be subjected to mechanical stress becomes asymmetric, thus producing birefringence phenomenon, so the polarization state of the light in the transmission of ordinary optical fiber will be completely irregular changes. Bias-preserving optical fiber can ensure that the polarization state of light in the transmission process remains unchanged, improving the coherent signal-to-noise ratio, and is widely used in aerospace, aviation, navigation, industrial manufacturing technology and communications and other areas of the national economy.

Fiber Array Polarization Maintaining Fiber Alignment System, specially designed for FA fiber alignment.

Light that is polarized is called polarized light. The extinction ratio refers to the ratio of the optical power P1 of the laser when emitting the full "1" code to the optical power P0 of the laser when emitting the full "0" code.
