In traditional 10G and 40G LAN networks, operators choose fixed passive filter technology or ROADM technology to deploy optical networks. Passive filters provide low-cost, easy-to-deploy point-to-point connections for LAN networks, but lack flexibility and scalability; ROADM-based LAN network solutions are easy to operate and flexible, but have high installation costs .
Unlike 10G and 40G LAN networks, 100G LAN networks use newly developed coherent packet optical technology, which has the same flexibility and scalability as ROADM-based networks, but without expensive wavelength selective switches (WSS) and Optical filter. With the help of coherent technology, 100G LAN network can not only support point-to-point transmission, but also point-to-multipoint transmission, so that the network is flexible and can meet future needs. In addition, 100G LAN network has the following advantages:
1. Larger capacity, the transmission rate of a single optical fiber is up to 100G, which can meet the needs of greater bandwidth;
2. Cost advantage, advanced technological innovation can help the network continue to reduce costs;
3. Higher competitiveness and higher scalability help network suppliers improve their competitiveness;
