What is wavelength selective detection?
From Wikipedia, the free encyclopedia. Wavelength selective switching components are used in WDM optical communications networks to route (switch) signals between optical fibres on a per-wavelength basis.
How many types of splitters are there?
From a technology standpoint, there are two commonly used types of optical splitters: Fused Biconic Tapered (FBT) Planar Lightwave Circuit (PLC)
How does wavelength selective switch work?
Multiple wavelengths received from the upstream network node are amplified and directed to the input port of the wavelength selective switch. The switch can select up to four of the wavelengths and pass each one to any of the four drop ports. Wavelengths not dropped are passed to the through port.
What is the function of WSS?
WSS stands for Wavelength Selective Switch. WSS has become the central heart of modern DWDM reconfigurable Agile Optical Network (AOC). WSS can dynamically route, block and attenuate all DWDM wavelengths within a network node. The following figure shows WSS’s functionality.
What is DWDM in networking?
Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology used to increase bandwidth over existing fiber networks. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber.
What is GPON splitter?
GPON Splitter: A passive optical fibre splitter that optically splits a single fibre into multiple fibres to each customer. 8:1 and 32:1 are the common maximum GPON split ratios we see with our carriers.
What is a WSS process?
A random process is called weak-sense stationary or wide-sense stationary (WSS) if its mean function and its correlation function do not change by shifts in time.
What is a 2 degree ROADM?
A 2-degree ROADM node contains two ROADM elements, with each ROADM element connected to a line (or degree). These ROADM elements are labelled A and B in the example.
