Different from 10g and 40g man, 100g man mainly uses the newly developed coherent packet optical technology, which has the same flexibility and scalability as ROADM based network, but does not have expensive wavelength selection switch (WSS) and optical filter. With the help of coherent technology, the wavelength of 100g man can be from any site to any site, any spectral width and any frequency as the center, so that the network is flexible and can adapt to the future.
The following are the main advantages of 100g man with coherent packet optical technology:
Higher capacity: 100g man provides 100gbps per fiber, which enables network operators to meet customers' demand for larger bandwidth;
Cost effectiveness: the consistency technology in 100g man can help to continuously reduce the cost per bit through advanced technological innovation.
High competitiveness: the ability of 100g man to do more with less money and to open services faster helps to improve the competitiveness of network providers.
How to build 100g man?
Metro transportation network can be divided into three sub layers: national or core layer, regional layer and convergence layer. The last two layers provide transport capabilities in different technologies - IP ran and PTN for mobile networks, and IP packet routing / switching for fixed broadband access.
Main equipment used in 100g man
Similar to 10g and 40g man, 100g man first uses 100g DWDM transceiver and dense wavelength division multiplexing (DWDM) MUX demux in the above core layer and area layer. In addition, optical amplifier and dispersion compensation module are needed in some application scenarios.
