What is Optical Modules?
Optical Modules, as an important part of optical fiber communication, are optoelectronic devices that realize the functions of photoelectric conversion and electro-optical conversion in the process of optical signal transmission. The optical module works at the physical layer of the OSI model and is one of the core devices in the optical fiber communication system. It is mainly composed of optoelectronic devices (optical transmitters, optical receivers), functional circuits and optical interfaces.
The transmitting interface inputs an electrical signal with a certain code rate, and after processing by the internal driver chip, the driver semiconductor laser (LD) or light-emitting diode (LED) emits a modulated optical signal of the corresponding rate. After transmission through the optical fiber, the receiving interface then converts the optical signal It is converted into an electrical signal by the light detection diode, and after passing through the preamplifier, the electrical signal of the corresponding code rate is output.
The Industry of Optical Modules
However, the independence of optical modules means that the scale of the industry is getting larger and larger. To reduce the cost of the industry, it is necessary to form some specific standardized systems after summarizing their respective design ideas, so that each manufacturer can be used in common and interoperable.
The low cost of optical modules is achieved through large-scale interoperability in the industry. The shape of optical modules has specific standards, the electrical interface has specific standards, the optical interface also has specific standards, and there are also standards for internal optical signals/electrical signals. Detailed specifications, digital diagnostic software interface also has a specific standard system.
When the industry chain manufactures optical modules, it will become "universal", buying the same type of laser chips, electrical chips, housings, etc., which is much cheaper than customizing. For module manufacturers, most of the steps of design and production are the same, and it is also low-cost for themselves. For Party A who buys optical modules, they can choose any supplier with low price and good quality. When optical modules meet the key factor of interoperability, the entire industry chain actually benefits.
How ORTE Photonics is integrated into Optical Modules
