WDM is a technology that enables multiple optical signals (wavelengths) to be transmitted simultaneously over a single fiber by assigning each signal a different wavelength. In fiber rings, WDM increases the capacity of the network, allowing more data to be carried without. The invention relates to a dual redundant fiber Ethernet transmission system, which comprises: FPGA chip, PHY chip and optical module, wherein the FPGA chip includes: the system comprises a first transmission control module, a second transmission control module, a network dual redundancy module and. FS adopts WDM technology, through M6200 series OTN transmission platform and OLP card, to achieve high bandwidth of data centers and ensure stable and transparent transmission of services, avoiding the impact of force majeure factors such as fiber breakage and earthquake on business. One key strategy for achieving this is through redundancy, which involves duplicating critical components or paths to ensure continued. Data transmission via optical fibers is considered particularly reliable. For even higher availability Fiber-To-The-Office (FTTO) networks can be designed using redundant cabling. • Locally through wired Remote Control (opt. Designed for CATV long-distance transmission and large User friendly USB port for SW up-grades and LAN port for full FTTH distribut on networks (PON). 1:1 redundancy is achieved by configuring the system using two transmitter modules with one RF splitter/combiner module at the transmit location, combined with two receiver modules and a.
