Compared with discrete optical fiber amplification technology, Distributed Raman Amplification (DRA) technology has shown obvious advantages in many aspects such as noise figure, nonlinear damage, gain bandwidth, etc., and has gained advantages in the field of optical fiber communication and sensing. widely used. High-order DRA can make the gain deep into the link to achieve quasi-lossless optical transmission (that is, the best balance of optical signal-to-noise ratio and nonlinear damage), and significantly improve the overall balance of optical fiber transmission/sensing. Compared with conventional high-end DRA, DRA based on ultra-long fiber laser simplifies the system structure, and has the advantage of gain clamp production, showing strong application potential. However, this amplification method still faces bottlenecks that restrict its application to long-distance optical fiber transmission/sensing

GPON (Gigabit-Capable PON) technology is the latest generation of broadband passive optical integrated access standard based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. Most operators regard it as an ideal technology to realize broadband and comprehensive transformation of access network services.

Scientists have developed a new type of laser that can generate a lot of energy in a short period of time, which has potential applications in ophthalmology and heart surgery or fine materials engineering. Professor Martin De Steck, director of the Institute of Photonics and Optical Sciences at the University of Sydney, said: The characteristic of this laser is that when the pulse duration is reduced to less than one trillionth of a second, the energy can also be "instantly "At its peak, this makes it an ideal candidate for processing materials that require short and powerful pulses.

Laser sensors are sensors that use laser technology to measure. It consists of a laser, a laser detector and a measuring circuit. Laser sensor is a new type of measuring instrument. Its advantages are that it can realize non-contact long-distance measurement, fast speed, high precision, large range, strong anti-light and electrical interference ability, etc.
