Background
Customer Name: IPNX
Industry: Internet Solution Provider
Company Size: 500-1000 staff
Customer Voice:
We intend to upgrade our backbone from 100G to 400G using a DWDM solution i.e using 4 x 100G
Kindly confirm if you have a DWDM solution that meets this request.
Please share a quote for the DWDM Solution. I shared the distances of the links.
Summarily, I would require the details of the DWDM equipment and the 100G DWDM Channel Transceiver Module
Challenge Request:
Using a pair of dark fiber (2 fiber cores) for the P2P link.
Share a solution that helps us achieve 400G I.E 4 X 100G
6COM Topology Design:

6COM Solutions:
According to customers’ requests and the real working environment, we lay out a non-coherent WDM DWDM passive system that can meet customers’ cost-effective solutions.

Customers Advantages:
- 100G DWDM QSFP28 ZR4 LC transceiver module is used in this solution.
- Using 100Ghz DWDM mux/demux to work with, can realize 400G service rate, and at the same time satisfy 4*100G service quantity, and can extend capacities as users request in the future, customers. at present the 100G QSFP28 can be replaced and upgraded to 6COM 400G for 4*100G capacity expansion later. 6COMGIGA can be upgraded to 6COM 400G for 4*100G capacity expansion later.
- 6COMGIGA provides customers with a variety of options to quickly upgrade to 400G (4*100G), this set of options for customers to provide a cost-effective solution for the current infrastructure can easily be achieved.
