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 […]
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 […]
Optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic device includes two parts: transmitting and receiving. The transmitting end converts the electrical signal into an optical signal, and after transmitting it through the optical fiber, the receiving end converts the optical signal into an electrical signal. structure The transmitting part […]
Step index fiber The script program contains a custom table, which is convenient for users to analyze the characteristics of step index fiber. (Friendly custom model) The user inputs fiber parameters such as core diameter, numerical aperture, etc., and can calculate the mode radius, mode field area, and effective refractive index. At the same time, […]
