Four Basic Elements in a WDM System

We know that fiber can carry more data over long distances than any other physical medium. That makes fiber a very precious material. And how to make the most use of your fiber plant becomes a question. So there comes Wavelength Division Multiplexing (WDM). Why Should We Deploy WDM? WDM can multiply your fiber capacity by creating virtual fibers. The…


How to Upgrade to 500G with 40CH DWDM Mux/Demux System?

Faced with the multifaceted challenges of increased service needs, fiber exhaust, and layered bandwidth management, the main challenge for service providers is to provide more and cheaper bandwidth and integrated services using different methods. Today, this article is to introduce a method that upgrades your network to 500G with DWDM (dense wavelength division multiplexing) technology. Why Use DWDM Technology? As…

Do You Know How to Save Fibers in Your Networks?

Do you know how to save fibers in your network to achieve economical cabling? Here may have the answer you want to know.

Decoding the Wavelength in Fiber Optics 1

Decoding the Wavelength in Fiber Optics

The wavelength, as we have been heard so many times in fiber optics, is not simply the term used to refine the color of the light. The light used in fiber optics is not the one that we can see by our eyes, as we use light in the infrared region which has wavelengths longer than visible light, typically around 850nm, 1300nm, 1550nm

Researchers Discover New Form of Light for Secure Optical Communication

Future Optical communications might be more secure thanks to Professor John Donegan and team for their research conducted at the Trinity College in Dublin, Ireland. The research team found a new property of light while passing it through crystals. Usually, when light hits our eyes, the spinning photons twist infinitesimally. In Quantum physics, the force of the twist/spin called the angular…

40G Bi-directional QSFP Transceiver

The virtualized workloads, cloud applications, and big data services today are driving previously server and data center fabric to an unimagined level. The existing 1Gbqs or 10Gbqs are gradually overwhelmed by higher-bandwidth like 40Gbps or 100Gbqs. Thus high-capacity optical technology and cabling infrastructure are required to support those servers and applications for 40Gbps upgrading. However, it might be too costly…
