There are 20 nodes which want to connect to eachother in fiber optic ring topology
the issue is that service provider just with one pair core (only)
the issue is I dont is this possib le weith regualt cisco switch or I should use CWDM ??
please give me some hint about this project
It sounds like your service provider is providing some form of metro-E solution or DWDM based solution.
What sort of configuration are they expecting at the handoff point ?
you know , we only have a single 2 core fiber and we should connect 20 node to eachother as a ring topology, it means a fiber must enter the switch and exit from the same switch, is it possible for switch to drop-and-insert fiber optic or not ?
