Maximum transmission distance of optical amplifier module
The transmission distance of optical module is divided into short distance, medium distance and long distance. ≥30km is long distance transmission. Light commonly used in optical fiber is 850nm. Dense Wavelength Division Multiplexing (DWDM) modules enable multiple optical signals at different wavelengths to be transmitted simultaneously over a single fiber, significantly increasing capacity without laying new fiber. Telecom-grade DWDM transceivers meet rigorous standards for optical power. We compared the transmission performances of 600 Gbit/s PM-64QAM WDM signals over 75. 6 km of single-mode fibre (SMF) using EDFA, discrete Raman, hybrid Raman/EDFA, and first-order or second-order (dual-order) distributed Raman amplifiers.

Typical Optical Amplifier Technology
Semiconductor optical amplifiers (SOAs) are amplifiers which use a semiconductor to provide the gain medium. These amplifiers have a similar structure to but with anti-reflection design elements at the end faces. Recent designs include anti-reflective coatings and tilted and window regions which can reduce end face reflection to less than 0.001%. Since this creates a loss of power from the cavity which is greater than the gain, it prevents the amplifier from acting as a laser.
