40G Ring Topology Network of Local Telecom Operator Netherlands- Case study

Background

Challenge

The customer needs to configure line redundancy and is not interested in OLP equipment. 

Solution

Engineers believe that a ring network is the most suitable solution. We connect all adjacent stations to ensure that each station can be connected in both directions. Since the transmission distance is all within 110km, we can use the 40CH DWDM in Data center and the 4CH DWDM OADM for each point. Amplifier and DCF equipment is required. It is necessary to reasonably control the wavelength input power of each node to avoid large optic power differences between wavelengths.

Customer Benefits

We built a protection mechanism using the redundancy of the ring network without adding additional equipment and increasing customer costs. At the same time, the management of FMT is simple and efficient, and even non-experts can configure each site network.
