   1. What is an optical module? 

    Borrowing the definition of Baidu Encyclopedia, the optical module is an optoelectronic device for photoelectric and electro-optical conversion. In summary, the optical module solves the problem that electrical signals cannot be transmitted in the fiber.

    There are many types of optical modules, but the working principle is basically the same. As shown in the following figure, the VCSEL is used as a optical source to emit an optical signal, and the optical signal enters the optical fiber for subsequent transmission, which is a coupling that is often said in the mouth.

  2. Where will the optical module be used?

  Similarly, in the optical communication that OC-001 you can understand, our daily life, such as online shopping, personal social, transportation system, aerospace system, etc., has a very complicated optical communication process that happens all the time. The corresponding optical module is applied in each scenario to maintain the communication process normally. Specifically, the optical module is mainly used in communication devices such as switches, fiber routers, video optical transceivers, optical transceivers, optical network cards, and optical fiber high-speed domes. 

What is an optical module ?

    Let's take a look at the actual application diagram. The optical module is installed in a variety of devices. Although you may not be able to see it, it must have a name in the life you are used to.
