【DWDM】400G OTN optical transmission 1-core bidirectional/single fiber
Introducing the DWDM/optical transmission device, a super high-speed 400G compatible single-core bidirectional/single-fiber solution.
By using a single-core bidirectional/single fiber, operational costs can be reduced by 50%, making dark fiber an affordable solution. In DWDM, active and passive solutions for single-core bidirectional/single fiber transmission can support from 4 wavelengths up to 8 wavelengths at 400G using optional optical amplifiers. Single-core bidirectional/single fiber solutions can seamlessly integrate with standard-based 10/25/100Gb Ethernet, 16/32G Fibre Channel, and OTU2/2e/4 client interfaces, enabling support for any combination of services up to 400G.
basic information
In fiber optic networks, traditionally, two fibers were needed simultaneously for sending and receiving signals. The bidirectional/single fiber solution has emerged as a way to reduce the costs of dark fiber solutions and optimize fiber usage. Instead of using two dedicated lines, it utilizes a single fiber line to transmit bidirectional signals. For companies borrowing dark fiber from providers, the operational savings are significant.

Applications/Examples of results
• In cases where laying new fiber is difficult or expensive in point-to-point, ring, or linear add-and-drop topologies. • Allows for the division of corporate traffic into two different fibers instead of using the same fiber for all traffic. • By using one fiber for transmission and reception and another as a backup, it is possible to enhance the reliability of existing dual-fiber solutions. ■ For detailed examples, please refer to the page below ■ https://packetlight.jp/singlefiber_solution/
