What are the types of optical amplifiers
Nov 18 , 2021
Optical amplifiers can be divided into two categories: One type is that semiconductor optical amplifiers are made of semiconductor materials and can be regarded as semiconductor traveling wave optical amplifiers without feedback. The other is a fiber amplifier, which includes two types, one is a nonlinear fiber amplifier, which uses a strong light source to excite the fiber, so that the fiber prod...

What is dcm dispersion compensation module？
Dec 29 , 2021
In the field of optical fiber communication, the dispersion compensation module (DCM) (also known as the dispersion compensation unit, DCU) is used to compensate for the dispersion, for example, to compensate for the dispersion in a long transmission fiber. Usually, this module provides a certain amount of dispersion, but there are also modules with tunable dispersion. Inserting the module into th...

Optical fiber coupler structure and principle analysis
Jan 26 , 2022
Optical fiber coupler is a kind of optical fiber passive device used for transmitting and distributing optical signal. Optical fiber couplers generally have the following characteristics: First, the device is composed of optical fiber, which is an all-fiber device; second, the demultiplexing and combining of the optical field are mainly realized by mode coupling; third, the optical signal transmis...

How to Use a Single Fiber CWDM Mux/Demux | Fiberwdm.com
Feb 11 , 2022
The biggest difference in the appearance of dual-fiber and single-fiber CWDM Mux/Demux devices is that the single-fiber version has a simplex line port. However, some of them are also made with duplex ports where only one port of the duplex is available and the other port is marked N/A. The main reason why this Mux/Demux enables bidirectional transmission is that it utilizes CWDM wavelengths diffe...

What Is WDM Fiber Network?
Feb 24 , 2022
The WDM fiber network divides an optical channel into several independent channels with different wavelengths, and transmits data through a single fiber. Therefore, it provides huge bandwidth by increasing the channels on a single fiber, thereby increasing its transmission capacity. Another breakthrough technology that enables high-speed data transmission is WDM fiber optic networking or wavelengt...

What is Dense Wavelength Division Multiplexing
Mar 08 , 2022
The so-called dense is relative to the interval between two adjacent wavelengths. In the past, the wavelength interval of the wavelength division multiplexing system was several tens of nanometers. Now the wavelength interval is only 02 to 1.2 nm. The spectrum allocation is shown in Figure 2-1. DWDM technology is actually a specific form of wavelength division multiplexing. Generally, the waveleng...

What is a fiber optic transceiver? What is the function of fiber optic transceiver?
Mar 25 , 2022
What is a fiber optic transceiver? Optical fiber transceiver is an Ethernet transmission media conversion unit that interchanges short-distance twisted-pair electrical signals and long-distance optical signals. It is also called a fiber converter in many places. The product is generally used in the actual network environment where the Ethernet cable cannot be covered and the transmission distance ...

Point-to-point 20-channel 100G DWDM QSFP28 55KM transmission - Fiberwdm.com
Apr 21 , 2022
With the explosion of network data flow, 100G transmission has begun to be widely used. At present, the traditional 100G/200G coherent optical DWDM CFP/CFP2 transmission solution is expensive and has a long lead time;FIBERWDM Ruid Ele-tech has launched a non-coherent 100G DWDM QSFP28 transmission solution through various efforts and cooperation, which has a good cost advantage in 100G short-distan...
