Wavelength conversion is the most common application of optical transponder in WDM system. As the BiDi single fiber owns two different wavelengths in one strand of fiber, the transmit (Tx) at one end of the fiber matches the receive (Rx) from the other end, and vice versa.įigure 3: Convert dual fiber to single fiber. In this case, two dual fiber switches of long distances are linked via two optical transponders. Dual fiber uses same wavelength over two different strands of fiber, while single fiber uses two different wavelengths over one strand of fiber, which is known as bidirectional (BiDi) transmission. Convert Dual Fiber to Single FiberĬonversion between dual fiber and single fiber is also required in networks. Typical application of this function is for extending the distances of 10G Optical Transport Network (OTN) and Synchronous Optical Network (SONET) ring.įigure 2: Convert multimode to single-mode fiber. For instance, the following two switches located far from each other are connected via two optical transponders that convert MMF to SMF. Mode conversion is needed when the transmission distance exceeds the limitation of MMF or when connectivity between a multimode device and a single-mode device is required. It is known to us that multimode fiber (MMF) is often used in short-distance transmission and single-mode fiber (SMF) is for long-distance transmission. These requirements are divided into three converting types in practical applications.

We need WDM transponder to traverse from one fiber optic network to another. Secondly, there is more than one fiber optic network provided by different providers and of different standards. Firstly, in a case where equipment of different wavelengths need to communicate with each other, the optical transponder can solve the incompatible problem between them. The optical transponder is needed in WDM system for several reasons.

Why Need Optical Transponder (OEO) in WDM System? Instead of simply regenerating the original signal during the process, modern WDM transponders are endowed with the 3R system (reshape, retime, reamplify), which is capable of cleaning up, monitoring and amplifying the signal accurately and closely. This process is commonly referred to as OEO (optical to electrical to optical) conversion.įigure 1: Schematic diagram of a fiber optic transponder. The transponder then converts the signal of standard optical wavelengths to an optical CWDM (coarse WDM) or DWDM (dense WDM) signal. That is to say, an optical signal received by the transponder is converted to an electrical data stream which it then processes and regenerates. It automatically receives, amplifies and then retransmits a signal on a different wavelength without changing the data/signal content. The optical transponder extends the transmission distance by converting the wavelengths and amplifying the signal. There are some omissions, though - no Java? - and with no updates since May 2016 these gaps may not be filled any time soon.An optical transponder consists of a transmitter and a responder, which is similar to a transceiver that includes a transmitter and a receiver. Verdict:ĭevDocs is easy to use and brings most of the documentation you need into one place.

Expand something like HTTP, select an interesting section such as Response Status Codes and click a code to find out what it means. You can browse them much like any other web-based manual. Click "Select documentation" bottom-left, check the boxes next to anything you need, click Save and the new technologies are collected together at the top of the sidebar.
