Applications:

1. Communication field
The 1270nm wavelength is one of the commonly used wavelengths in optical fiber communications. It is located in the window region of the near-infrared spectrum, where optical fibers have less transmission loss for this wavelength. Therefore, the 1270nm wavelength optical signal can maintain low attenuation and high signal quality during long-distance transmission.
In fiber optic communications, the 1270nm wavelength is commonly used for data center interconnections, local area network connections, and long-distance fiber optic communications. Its applications also include metropolitan area networks, communication power line monitoring and sensing, and passive optical networks.

2. Optical fiber sensing field
Light with a wavelength of 1270nm is widely used in the field of optical fiber sensing. Due to its high coupling efficiency with optical fiber, it can make full use of the sensing performance of optical fiber. By utilizing changes in weak optical signals in optical fibers, high-precision measurement of physical quantities such as temperature, pressure, and deformation can be achieved.
For example, in the fields of industrial control and safety monitoring, 1270nm wavelength optical fiber sensing technology is widely used in temperature monitoring, strain monitoring, and structural health monitoring. In addition, light of this wavelength is also used in geological exploration, fiber optic gyroscopes, medical equipment and other fields.
