What Are the Differences Between QSFP28 and CFP Optics?

With the upgrade of the optical network from 10G to 100G, the development trend of 10G-25G-100G/10G-25G-50G-100G starts to prevail in the optical market. In the development process of 100G optical transceivers, their form factor type and standard are developed according to the cost and power consumption, which are regarded as the main drive in the development of the interconnect market….

An Overview of DWDM: Definition, Advantages and Applications

When capacity expansion takes place in traditional network transmission, Time Division Multiplexer(TDM) and Space Division Multiplexer (SDM) are adopted. Both of transmission networks use a single wavelength signal for data transmission. However, this transmission method does not make full use of optical fibers with a large capacity as the transmission medium, resulting in great waste. To deal with the issue, the…
