Point to Point DWDM Solution
First of all, we need to understand the needs of customers. The distance of transmission, the business that needs to be transmitted at present and whether it will be expanded in the future, the loss of optical fiber, single fiber or dual fiber.
Then, we start to calculate OSNR, as well as power loss, whether to add an amplifier, dispersion, etc.
Finally, the received optical power is within the sensitivity range of the received optical power, then the link we designed can pass.
