Common Solutions for A Secured DWDM Network

Common Solutions for A Secured DWDM Network DWDM (Dense Wavelength Division Multiplexing) is an optical technology used in fiber optics to increase bandwidth over existing fiber optic backbones. Due to the large capacity, high survivability and flexibility, DWDM technology is common to be seen in backbone network and long haul transmission. However, in the actual cases, problems like optical fiber faults and line interruption may affect the communication and services tha

What Is OTN — Optical Transport Network?

With the explosion of digital traffic and the ever-growing array of bandwidth-hungry applications, OTN (Optical Transport Network) evolves from point-to-point DWDM remedies to scalable and robust optical networking applications that cater to a wide variety of client signals with equally-varied service requirements. Carriers are also placing particular emphasis on OTN in the Metro area, where it is shifted rapidly from SONET/SDH to WDM (wavelength-division multiplexing). With the goal of boosting
