[High-tech LED News] ST Ganhua announced that it is accelerating the construction of LED epitaxial wafer production enterprises. In order to speed up the construction of the company's LED epitaxial wafer production project, Guangdong Deli Optoelectronics Co., Ltd., a wholly-owned subsidiary of the company, plans to participate in bidding for land and auction. The starting price is 59.41 million yuan. The optical module (optical module) is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic device includes two parts: transmitting and receiving.
Simply put, the function of the optical module is to convert the electrical signal into an optical signal at the transmitting end, and after transmitting through the optical fiber, the receiving end converts the optical signal into an electrical signal.
The optical module is an optoelectronic device that performs photoelectric and electro-optical conversion. The transmitting end of the optical module converts electrical signals into optical signals, and the receiving end converts optical signals into electrical signals. Optical modules are classified according to the packaging form. Common ones include SFP, SFP+, SFF, Gigabit Ethernet Interface Converter (GBIC), etc.
The transmitting part is: the electrical signal with a certain code rate is processed by the internal drive chip and then drives the semiconductor laser (LD) or light-emitting diode (LED) to emit the modulated light signal of the corresponding rate. The internal optical power automatic control circuit makes The output optical signal power remains stable.

ST Ganhua said that if the land use right is successfully won, it will be beneficial to the implementation of Deli Optoelectronics LED epitaxial wafer production project and the company's sustainable and healthy development in the future. 
The receiving part is: the optical signal of a certain code rate is input into the module and then converted into an electric signal by the light detection diode, and the electric signal of the corresponding code rate is output after the preamplifier.
