40Gb/s DWDM DQPSK with EDFA and WSS ROADM architecture….say what?


The fiber optic communications industry can often sound like an alphabet soup. For example, when we talk about common transceiver/transponder form factors, you often hear terms like SFF, SFP, SFP+, XFP, XPAK and X2. In the ROADM world, a WSS stands for Wavelength Selective Switch and ROADM means Reconfigurable Optical Add/Drop Multiplexer. These short acronyms may save a few important minutes in your day by facilitating more efficient communication not to mention a few vital breaths. Needless to say, there is an endless list of commonly used acronyms in our industry.That all said, I have often found it helpful to refer to the Common Industry Acronym List created by our very own marketing team. The Finisar acronym reference guide provides a short list of commonly used acronyms in the optics industry. So if the first things that comes to mind when you see the letters “RFoG” is a small green amphibian (not Radio Frequency over Glass), then go ahead and look it up on our blog.
