Ring Network

[roland1976]

HI I need your help. We are planning to build a network with fiber ring type topology. I want to know what are devices to use. The ring consist of total 4 location one of them is data center. Some told me about Cisco ONS to fulfill this task. What are latest technology used by this scenario. Thank you.

Hi,

In your case you have to check CWDM Solutions if fiber length is not longer than about 80 km:

The WDM technology is commonly used nowadays, but with such limited information, we can't provide more specific advice, so you should attach a brief diagram of your network !

For just four locations, in a ring, curious why you believe you need to create an optical network rather than just use optics with a digital network.
