The customer is a telecom operator in Paris, France. It has many businesses in many regions of France and has a certain popularity in the local area. With the development of business, the early national 10g backbone network can not meet the needs of business development. Now we need to build a national backbone network of 400g roads, with a total of more than 70 kilometers of long link transmission.

Business challenges

1. The adjacent service stations are far away, the maximum single span is about 78km, and the cumulative loss of optical fiber line is large;

2. It needs to be compatible with the equipment laid earlier in the early stage;

3. Remote installation and commissioning services are required;

4. The construction budget is low.

Solution

1. The OTN8800-VI system is used to build the backbone transmission network solution, which can not only meet the transmission needs of customers, but also be well compatible with the equipment in the early stage, and the construction cost is lower than that of other manufacturers;

2. FB-LINK technical engineers provide remote guidance to help customers install and debug equipment until the service is opened;

3. At the same time, it provided customers with training on equipment operation, use and operation and maintenance;
