Application Cases of 10G CWDM Network. CWDM network, as an easy-to-deploy and cost-effective solution, has been applied in many areas.
Although CWDM network is not as perfect as DWDM networks in data capacity, it still can satisfy a wide range of applications in optical applications. And CWDM is a passive network, allowing any protocol to be transported over the link, as long as it is at the specific wavelength. This article is going to describe several application cases of 10G CWDM networks in different areas. Benefits of 10G CWDM Network Although 40G and 100G networks are developing rapidly, many of them still need to grow on the basis of 10G networks. Understanding WDM MUX/DEMUX Ports and Its Application. Wavelength division multiplexing (WDM) is a commonly used technology in optical communications.
It combines multiple wavelengths to transmit signals on a single fiber. To realize this process, CWDM and DWDM mux/demux are the essential part. As we all know, there are several different ports on the WDM mux and demux. How to Calculate Power Budget and Link Distance in CWDM Network. By multiplexing separated wavelengths from multiple ports onto a single fiber in the network, coarse wavelength division multiplexing (CWDM) network increases fiber capacity at a low cost.
And all the CWDM components are passive and do not need power, which requires lower investment than DWDM networks and make it popular. This article intends to explore how to calculate the power budget and link distance in CWDM network, offering more conveniences for your CWDM network deployment. Understand Optical Power Budget in CWDM system One important factor of network design, including various optical networks like DWDM and PON, is the optical power budget.
Optical power budget is the amount of light available to make a fiber optic connection. Link Power Budget = Min Transmit Power – Min Receiver Sensitivity. Single Fiber Solution in WDM System. As we all know, fiber optical networking has two transmission ways: dual fiber transmission and single fiber transmission.
The difference between them is that the former one requires two fibers—one is for transmitting and the other is for receiving, while the latter only uses one fiber for both transmitting and receiving. Analysis of OEO Transponder Application in WDM Network. Anyone who has experiences of deploying WDM networks, either DWDM or CWDM networks, may be familiar with OEO transponder.
Since in WDM network deployment, especially for long haul transmission, OEO transponder plays an important role. OEO transponder, also known as WDM transponder, means optical-to-electrical-to-optical. That is to say, it converts an optical signal to an electrical signal, and then recovers it to an optical signal. In some cases, OEO transponder serves as fiber mode converter or repeater for long distance transmission. Functions of OEO Transponder. How to Calculate DWDM System Loss in Long Haul Transmission. Nowadays, high capacity network is needed to deal with large amount of data transfer.
The application of DWDM (dense wavelength division multiplexing) system is a commonly used technique to enhance network capacity. Due to its complexity caused by various components like EDFA and dispersion compensating module (DCM), it may be difficult to calculate the loss over the whole links, especially in long haul transmissions. Options Upgrading to 100G Connection. With growing data traffic volume in recent years, the existing 10Gb/s optical networks are becoming saturated, which drive the great need for 40G and 100G networks.
In turn, 100G network also can bring benefits for network operators. For example, 100G network can reduce the cost per bit, improve the utilization of existing fiber and reduce the network delay. Solutions to Achieve Long-haul Transmission With DWDM Systems. In order to increase the transmission distance of optical signals, many technologies, like the TDM (time division multiplexing) and WDM (wavelength division multiplexing), have been used.
Expect for that, several optical components like single mode fiber optic cables, optical amplifiers and dispersion compensating modules (DCMs) are also put into use to realize the goal. Today, this article intends to illustrate the solutions to achieve longer transmission distances with DWDM technology. Solutions to Extend Transmission Distances When it comes to long-haul optical transmissions, DWDM (dense wavelength division multiplexing) is a topic that cannot be ignored.
DWDM technology enables different wavelengths to transmit over a single optical fiber. Solution One The first solution is suitable for applications that are less than 50km. Notes: this solution is the basic application of DWDM Mux/Demux in a relative long distance comparing to CWDM technology which suits short distance deployment.
Advantages and Disadvantages of Direct Attach Twinax Cable. Driven by need for high speed Ethernet and increasing services like Cloud and virtual data center, many data centers have been loaded with numerous cables and various equipment.
Due to this case, shortage of data center space is common but it’s getting difficult and expensive to build new or expand existing locations. Today this post intends to introduce a type of cable—direct attach twinax cable, which can solve this problem effectively. Overview of DAC Direct attach twinax cable is a type of copper cable similar to coaxial cable, but it has SFP+, QSFP+ or QSFP28 plus at each end integrated. DACs are usually used in data centers for short transmission between racks. On today’s markets, in order to satisfy the ever growing need for cost-effective delivery of more bandwidth, there are mainly three kinds of DAC according to the transmission rate: 10G SFP+ DAC, 40G QSFP+ DAC and 100G QSFP28 DAC.
The last one is 100G QSFP28 DAC. Getting More Benefits From Sensing Fiber Optic Cables. Sensing fiber optic cable is a type of optical cable that can monitor temperature, strain, acoustics and pressure.
They are suitable for a wide range of applications like fire detection, vibration monitoring, industrial plant temperature sensing, temperature gradients in soil, pipeline leak and intrusion detection. Although these cables are built based on standard fiber optic cable which only operates to 85℃, the highest working temperature of them is up to 700℃. Before knowing what benefits that sensing fiber optic cable could bring to our life, let’s figure out the common types of sensing optical cable at first. PON Transceivers for FTTH Applications.
