It is used to change the optical path or transform the optical mode in optical system. Different fields require for different fiber lenses. In terms of the shape of lenses, they can be divided into inclined plane, wedge (double inclined plane, or four inclined plane), sphere, conical, etc., as shown in picture below. Moreover, lensed optical fiber can also be divided into single fiber lens and fiber lens combination based on the form of fiber lens. This paper mainly introduces the principle and application of different types of fiber lenses.

However, it could only accomplish the one-way up and down wavelength of optical network nodes. Around 2008, the replaceable OADM (ROADM) technology appeared, enabling the optical layer to have the function of all-connected exchange. Its main structure is a multi-dimensional ROADM (MD-ROADM) based on multiple 1XN selective switching (WSS) units, according to the different implementation modes of optical switching nodes in local upper and lower wavelength. ROADM went through three generations, and it succesffully made the switching function more and more complete and the networking more and more flexible. The development history of all-optical exchange is shown in Figure 1 below.
