How to Build up a 100G Metro Network?

100G metro network mainly uses the newly-developed coherent packet-optical technology which provides flexibility and scalability as much as the ROADM-based network but without its costly wavelength selective switches (WSS) and optical filters. How to build a 100G Metro Network? This post will give a comprehensive description.

Optical Amplifier – EDFA (Erbium-doped Fiber Amplifier) for WDM System

Optical amplifiers serve as an integrated part of long haul data transmission. The most prominent feature of optical amplifier is that the device can amplify optical signal directly without the need to convert the signal into an electrical one before amplifying. EDFA (Erbium-doped Fiber Amplifier) is the one type of many different optical amplifiers that can achieve signal amplification over long-hual optical communication.Optical Amplifier BasicsWhen transmitting over long distance, the optical

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
