Working Principle of the PM8534B-FEI

The PM8534B-FEI working principle is based on the Vertical Cavity Surface-Emitting Laser (VCSEL) technology. VCSELs have a simple construction consisting of an active layer of semiconductor material sandwiched between two top and bottom mirrors. The active layer is pumped to produce light that is then emitted from the surface of the chip in a narrow beam. When incoming light from an external source is incident on the VCSEL, it is reflected from the mirrors and is detected by the receiver.

The VCSELs used in the PM8534B-FEI have a low power consumption and an excellent modulation capability. This enables it to achieve high-speed communication over a wide range of distances. The transceivers are also designed with temperature compensation and equalization algorithms that help maintain a high degree of accuracy and reliability.
