Function of CWDM filter
Jan 18 , 2022
CWDM filters are designed to multiplex and demultiplex wavelength signals in metro, access and enterprise networks, as well as cable television applications. Additionally, they are often used to provide the wireless backbone for the latest 4G wireless networks (LTE). They are a low-cost approach for systems using uncooled laser sources and an alternative to more expensive DWDM components based on ...

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...

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...

Main advantages of BiDi optical transceivers on the market
Mar 18 , 2022
With the development of technology, a new type of pluggable optical transceiver, BiDi fiber optic transceiver, has been developed, combining transmit and receive functions on a single fiber (single-mode or multi-mode). The following figure shows the difference between ordinary optical transceivers and BiDi optical transceivers. How do BiDi transceivers achieve optical channel transmission over fib...

Working principle and features of 40G QSFP+ BIDI transceiver
May 10 , 2022
A BIDI transceiver is called a bidirectional transceiver, it operates on two different wavelengths and transmits in both directions over only one fiber. To distinguish, BIDI transceivers have only one connection port, while ordinary optical transceivers have two ports. Why can signals with different center wavelengths be sent and received bidirectionally in a BIDI transceiver? It is very important...

What is a CWDM/DWDM multiplexer/demultiplexer?
May 20 , 2022
As we all know, WDM (Wavelength Division Multiplexing) is a technology that uses multiple lasers to send multiple lasers of different wavelengths on a single fiber at the same time. It can realize two-way communication on one fiber and increase network capacity. In a WDM system, a multiplexer is generally used at the transmitting end to multiplex several optical signals into a bundle of optical ca...
