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 […]
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 […]
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 […]
1 Introduction G. 657 optical fiber is also called bending loss-insensitive optical fiber. The fiber optic cable that is thinner than ordinary telephone line used for FTTH entry is G. 657 fiber. Without G. With 657 fiber, there is no large-scale application of FTTH. G. 657 optical fiber is divided into multiple sub-categories, currently commonly […]
Fiber patch cords can be divided into simplex and duplex according to the working mode of the interface. What is simplex and duplex? Both simplex and duplex are two modes of communication channels in telecommunications and computer networks. Simplex and duplex jumpers can also be called single and double (single core, dual core). What is […]
Can the optical fiber convert the network cable? Optical fiber is a kind of light-guide glass fiber, which transmits optical signals and cannot be directly connected to network cables. It needs to use photoelectric conversion equipment to convert optical signals into network signals. Common photoelectric conversion equipment includes household optical fiber cat equipment, optical fiber […]
