This is another example of a double-clad fiber amplifier. Different from the above example, we consider all cladding modes and use the built-in mode solution method. According to the refractive index distribution, the numerical aperture of the core, and the conditions of the cladding pumping mode, the mode characteristics are calculated. For simplicity, set the […]
The intensity of the optical signal received by the optical receiving device needs to be within a certain range, and the optical power cannot be too strong or too weak, otherwise the life of the device will be shortened or it will not work normally. The optical fiber attenuator is an optical passive device that […]
In the construction of metropolitan area networks (especially long-distance OTN optical transmission networks), wavelength division transmission equipment is particularly important. DWDM dense wavelength division multiplexing equipment has long-distance and high bandwidth transmission capabilities; CWDM coarse wavelength division multiplexing equipment has relatively Low cost. So if you choose the right wavelength division multiplexing equipment to build […]
Optical transceiver is the terminal equipment for optical signal transmission. We will inevitably encounter some problems during use. Next, the editor of Amini Technology will list some common problems encountered in the use of optical transceivers and the corresponding solutions in detail. Program, friends who are interested, let’s take a look! (1) What is the […]
Nowadays, in the current network communication projects, optical fiber terminal, optical fiber transceivers, and optical modems can be said to be widely used and highly respected by security personnel. So, are you concerned about the difference between these three? Is it clear? Next, the editor of Amini Technology will introduce the difference between optical transceivers, […]
The safety light curtain is also the photoelectric safety protection device (also called safety protector, punch protector, infrared safety protection device, etc.). In modern factories, humans and machines work together on some potentially dangerous mechanical equipment, such as stamping machinery, shearing equipment, metal cutting equipment, automated assembly lines, automated welding lines, mechanical transmission and handling […]
Adopting advanced uncompressed digital high-definition video and high-speed digital optical fiber transmission technology, it can easily transmit the VGA high-definition video signal of various resolutions output by the computer host, high-definition video signal source, high-definition DVD/DVR and other equipment to the remote end. Of the device. So, what are the product characteristics and technical parameters […]
(Note: If passive optical fiber is used, this file and the following case files will not work.) This program helps to learn the basic operation of the software. A simple yttrium-doped fiber amplifier is designed. Both the pump light and the signal light are transmitted in a single-mode fiber. Each wave symbolizes an optical channel. […]
By coherently combining multiple ultrafast fiber lasers, the power limitation of a single fiber can be overcome. In this kind of coherent combining device, a polarization beam splitter (PBS) is generally used for beam combining (as shown in Figure 1(a)), but this kind of device is more complex, and as the number of combined channels […]
The 100M optical fiber transceiver (also known as the 100M photoelectric converter) is a fast Ethernet converter. The optical fiber transceiver is fully compatible with IEEE802.3, IEEE802.3u, and IEEE802.1d standards. It supports three working modes: full duplex, half duplex, and adaptive. Gigabit optical fiber transceiver (also known as photoelectric converter) is a fast Ethernet, its […]
