Optical module, including a lens module, a temperature compensation element, a temperature sensor and an electronic control unit.

The optical module consists of optoelectronic devices, functional circuits and optical interfaces, etc. The optoelectronic devices include two parts: transmitting and receiving.

Simply put, the role of the optical module is to convert the electrical signal into an optical signal at the transmitting end, and then convert the optical signal into an electrical signal at the receiving end after transmission through optical fiber.

The optical module is an optoelectronic device that performs photoelectric and electro-optical conversion. The transmitter side of the optical module converts electrical signals into optical signals, and the receiver side converts optical signals into electrical signals. Optical modules are classified according to the package form, and the common ones are SFP, SFP+, SFF, Gigabit Ethernet Road Interface Converter (GBIC), etc.

Transmitting part.

Input a certain code rate of electrical signals through the internal driver chip processing to drive semiconductor lasers (LD) or light-emitting diodes (LED) to emit the corresponding rate of modulated optical signals, its internal with optical power automatic control circuit, so that the output optical signal power to maintain stability.

Receiving part.

A certain code rate of the optical signal input module by the light detection diode converted into electrical signals, after the preamplifier output the corresponding code rate of the electrical signal.
