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...

Cost-effective advantage of 100G DWDM QSFP28 transmission solution | Fiberwdm.com
Feb 18 , 2022
In recent years, the single-wave 10G transmission mode has been the protagonist of the stage. However, with the popularization of 5G networks, the rise of the Internet of Things, and the application of big data, the data transmission capacity has exponentially increased, and the single-wave 10G transmission The speed will no longer be able to meet the needs of big data; the new corner of the forme...

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...

Why Choose a 40-Channel DWDM Multiplexer/Multiplexer
Mar 04 , 2022
DWDM (Dense Wavelength Division Multiplexing) is an ideal optical multiplexing technology for long-distance data transmission, which can put multiple channel information using a single wavelength on the same fiber and greatly improve the transmission capacity of optical networks. At present, DWDM technology is widely used in telecommunication networks and has become the choice of many telecommunic...

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...
