Sharing some cost-effective optical networking solutions. Enjoy myself.
Driven by the undeniable growth in demand for bandwidth of private and public cloud data centers, 25G Ethernet over a single lane has become the new trend for sever-to-switch interconnections. And the increasing requirements of higher speeds in data centers...
Gigabit network switches connect Ethernet devices in a network while providing great performance capabilities. In many network structures, gigabit Ethernet switches are often used as access switches that connect devices in a local area network. As the...
Stacking switch is a common technology used in network design, especially when large numbers of ports are required in data centers or large size networks. Stack switch not only provides high performance, but also maximizes network scalability and simplify...
Ethernet switches can be regarded as the “brain” of a network. In today’s market of network switches, there are mainly three types of Ethernet switches: managed switch, smart switch and unmanaged switch. Like the discussion about managed vs unmanaged...
As the total expenditure decreases of 10GbE network and the increasing data traffic in modern business, the specific demands for 10GbE switches have been put forward. As we know, there are 8-port 10GbE switch, 12-port 10GbE switch, 24-port 10GbE switch...
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...
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...
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...
Based on the same concept of using multiple wavelengths of light on a single fiber, CWDM and DWDM are two important technologies in fiber optical communications. As we all know, although the transmission distance of CWDM network is shorter than that of...
Purpose built for converged networks where video, voice and data are carried over a single network platform, PoE switches with 8 port, 24 port and 48 port represents an ideal solutions for different size networks like home or SMBs (small and mid-size...
When network designers build their networks, there is a common problem that they may meet: whether to stack switches or not. Because, limited by the switch port counts, designers have to get more switches or stack switches to meet network build requirements....
CATV technology has matured steadily over the past several years, and has expanded into diverse applications. However, as the quick expansion in technology and services, it’s important to improve CATV network component performance for higher visual and...
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...
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...
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,...
PON (passive optical network) is one of a common optical fiber network architectures. It is characterized by the “splitting” of the optical fiber one or more times, resulting in the sharing of optical fiber among multiple users. However, as networks grow...
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,...
DWDM MUX/DEMUX plays a critical in WDM network building. 16 channels transmission is very common in DWDM networks. How to realize it in a simple way? This article intends to introduce two solutions to achieve 16 channels with different types of components....
The performance of Ethernet switches is important in network design, for it will affect the whole network system working. Therefore, to achieve high performance, network managers may use different methods to improve performance of network switches, which...
As the ever-increasing of small business, Ethernet switches with PoE (power over Ethernet) technology to realize real-time monitoring and management. 8-port PoE switch is one of the commonly used PoE switches in business networks. Considering different...
As the growing of business and the increasing awareness of security, IP cameras are widely deployed in areas like schools, public areas and even at home. All these arouse the increasing demand for PoE (power over Ethernet) switches which enabling big...
Each power supply has a separate power cord to support its work. Server power cord connecting the servers and PDU (power distribution unit) plays a critical role in this process. Since the power cords standard for connector types and voltage levels varies...
