Optical modules, also known as optical transceivers, are essential components that convert electrical signals to optical signals and vice versa. They form the backbone of long-distance, high-capacity data transport in modern telecom networks. That is, metal medium communication represented by coaxial cables and network cables is gradually being replaced by optical fiber media. These modules typically consist of a transmitter, which converts electrical signals into a light signal, and a receiver, which converts the received signal back.

At the heart of every optical transceiver lie three essential components, often called the “Three Pillars” of optical communication: Laser — generates light. Modulator — encodes data onto the light. Photodiode — decodes light signals back into electrical form.

Average Optical Power: How bright the light is (measured in dBm). Too dim? Your signal gets lost in the fiber. Extinction Ratio: The difference between “on” (1) and “off” (0) light power. A higher ratio = cleaner signals. Transmitter Side: An electrical signal hits a laser diode (LD) or LED, which spits out light. Receiver Side: Light enters a photodetector (like a tiny solar cell), which turns it back into electricity. A built-in amplifier boosts the signal for your. The average transmitted optical power refers to the optical power output by the light source at the transmitting end of the optical module under normal working conditions, which can be understood as the intensity of light.
