C-Bus network design

I need some help with network design for an upcoming c-bus job.

The job has 5 existing c-bus networks which are all individually linked to one main netork which then runs scedule plus all working fine.

The job site is expanding with a possiable two more netwoks.One network is proberly 800m (cable length) away fom the main network the other 1.2 km (cable length) away from the main network this is a comertial site where at each of the remote netwoks there will be a local LAN which is connected over fibre back to the main building where the main c-bus network and the scedule plus is.

What would the best way for me to connect to these neworks with the large distances either i could run a c-bus cable to both networks and install network bridges at both ends of the cable to help with distances.

Or should i just us a CNI and tap into the lan at each remote network.

Both of the netwoks do not need to send any c-bus comands to any other network except the main netwok

If you go the CNI (ethernet) route, there are a couple of options you have.

You can either plug directly into the on-site network, and just have the IT department assign you static IP addresses for the CNI's, and let them worry about the fibre backbone.

OR...

If the underground fibre they are using has a spare pair within it, you could pick up a couple of copper to fibre media converters, connect one at each end to the spare fibre pair, and run your own "private" LAN that way.

CNI is the only way to go!!!! Your cable lengths are too long to go with bridge options
