| Descripción : | DWDM as optical transmission technology has evolved after previous SONET / SDH technology has reached its limitations in terms of ecosystem components to achieve high-speed data transmission at competitive prices on fibers. The basic unit for the speed of data transmission through said system was OC3 or STM-1, which consists of 155 Mbs. The highest speed commonly implemented is the OC-768 or STM-256 circuit, which operates at a speed of just under 38.5 Gbit / s. The combination of the first laser sources and the electronic circuits that transmit at 1310 nm in single-mode fibers, with the method of obtaining higher signals by time division multiplexing to form the next level in the SONET hierarchy, has reached exhaustion of the fiber bandwidth. CWDM and DWDM solutions are available as active or passive systems. In a passive, powerless solution, the WDM transceiver resides directly on the data switch. The WDM transceiver output connects to a non-powered multiplexer that combines and redistributes, multiplexes and demultiplexes the various signals. Since the WDM transceiver resides on the data switch, it means that all WDM functionality is built into the data switch. Active CWDM / DWDM solutions are autonomous AC or DC powered systems separate from the switch. The task of the autonomous system is to take the fiber's short-range optical output signal or IP switch and convert it to a long-range WDM signal. This OEO (optical to electrical to optical) conversion is handled by a transponder. The converted WDM signal is then transmitted with the help of transceivers and multiplexers. Due to the separation of the WDM transport solution from the actual switch, active systems also tend to be more complex than passive and integrated solutions. |
