What would you do if your network capacity can not meet your requirement? Will you put more fibers or update your system? In fact, these two methods are not very recommendable. Why? As your fiber cabling infrastructure is limited for adding fibers and high cost is required for upgrading system, these two methods are unworkable… Continue reading Dual-Fiber or Single-Fiber CWDM Mux Demux for Higher Capacity Need?
As the development of 100G Ethernet becomes a trend, the demand for 100G optical modules is increasing, and today 100G optical modules represent a significant portion of the network construction cost. Three solutions have emerged in the 100G 80km DCI space, namely 100G coherent, 100G PAM4 DWDM and 100G QSFP28 ZR4. 100G QSFP28 ZR4 Introduction… Continue reading 100G QSFP28 ZR4, The best choice for 100G long haul Data Center Interconnection
Dense Wavelength Division Multiplexing(DWDM) systems are an important part of modern long-haul backbone networks and metropolitan networks. In long-haul transmission applications, fiber attenuation and dispersion are the main factors affecting optical signal transmission, so active devices such as Erbium Doped Fiber Amplifier (EDFA) and Dispersion Compensator (DCM) are commonly used in Dense Wavelength Division Multiplexing (DWDM)… Continue reading Do you know the EDFA and DCM in DWDM system
