The 1*9 module is mainly used in PDH equipment. It is widely used in the end access of public communication networks, large customer access networks and private networks. SFP products are mainly used in switches and routers; they are widely used in backbone networks and metropolitan area networks.

The PID is a highly sensitive and versatile detector, and the PID can be viewed as a “low concentration LEL detector”. If you look at toxic gases and vapors as a big river, even if you swim into the river, the LEL detector may not respond, and the PID has already told you when you have just wet your feet.

A fiber grating is a diffraction grating formed by axially modulating the refractive index of a fiber core by a certain method, and is a passive filter device. Because the grating fiber has the advantages of small size, small welding loss, full compatibility with fiber, and ability to embed smart materials, and its resonant wavelength is sensitive to changes in temperature, str...

Solid-state, reverse-emission, low-cost VCSEL (Vertical Cavity Surface Emitting Laser) for LiDAR (Lidar) and 3D sensing applications, lighting module leader TriLumina, will be demonstrated at CES 2018, its 3D LiDAR, and 3D sensing solutions Program.

According to the wavelength of the laser output wavelength, it is classified into S-band (1460~1530 nm), C-band (1530~1565 nm), and L-band (1565~1610 nm).

With the rapid development of sensor technology, sensor nodes have spread all over lighting equipment, clothing, food packaging, even inside the human body or embedded in the skin, but they must meet some challenging new requirements:

The working medium used in the fiber laser has the form of fiber, and the fiber laser characteristics are affected by the fiber conducting properties.

A fiber amplifier is an optical amplifier component that directly amplifies an optical signal by a fiber optic communication system. In a communication system using an optical fiber, there is no need to convert an optical signal into an electrical signal and directly amplify the optical signal.
