What about Single Model and Multi Model Cable? Single Model Features: 1> Single mode cable is a single stand of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. 2> Single Mode Fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310nm or […]

1、How to remove scratches? Why the scratches are produced： (1) The time of medium polishing is too short：every process is to reduce the roughness of the end-face. If the polishing time is not enough, some big scratches will remain on the end-face, and HF5D has no way to remove these big scratches. Performance: Deep and

Differences between the 3 Common End-face Types 1、Why should fiber optic end–faces be polished? With connectors mounted on one fiber end-face, return loss is unavoidable, which occurs due to reflections from the light source. Severe light loss can damage the laser light source and interrupt the transmitted signal. In order to allow better contact between

Application of PM Fiber Because of the function of maintaining the polarization state of light (e.g.,【Picture 1】), the applications of PM fibers cover a variety of fields such as communications, medicine, sensing, and military, etc. In addition to typical deflectors, coherent communications, and hydrophones, some other applications of PM fibers will be introduced here. 【Picture 1】Structure of a

What’s the Fast and Slow Axis？ Polarization Maintaining fibers work by inducing a difference in the speed of light in the two perpendicular polarizations passing through the fiber. This birefringence creates two major transmission axes within the fiber, called the fast and slow axes of the fiber. The fast axis is the direction of the small

What’s Polarization Maintaining Fiber？ Before understanding what a PM fiber is, let’s look at what polarization properties are first. Polarization is a property of transverse waves, which refers to the nature of transverse waves oscillating in a particular direction in a plane perpendicular to their direction of propagation. Light is an electromagnetic wave that propagates as

Categories of Polarization Maintaining Fibers 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. According to the generation mechanism of the birefringence phenomenon, it can be divided into structural birefringence and stress

Principle of Polarization-Maintaining Fiber 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
