    Hi,

    Could anyone please help with this if possible.

    We are busy with a proposal where we need to switch loads over a minimum distance of 10 kilometres. Using network bridges seem very cumbersome and obviously lightning is ever imminent in South Africa. Having power available for PSU's along this route may also be a problem.

    Would optic fibre be a viable solution to achieve these distances and what C-Bus and other hardware would be involved.

    Thanks

    Probably

    I guess you would need to build a backbone using CNI's and plug these into ethernet to fibre media convertors, and maybe install solar powered drop stations along the way if the fibre transmitters won't do 10kms in a single hop.

    Can't be done.

    This was discussed previously here in this forum
    http://www.cbusforums.com/forums/showthread.php?t=4174

    I wish there was a way to bridge two network together via ethernet (CNI's), or a transciever for fibre, but as of yet, Clipsal do not see a need for this functionality.

    Hmm, I wonder if a pair of 5000SM/2's with a couple of glue micros with ethernet capability would do the job. wouldn't even need to use a true IP proto stack for basic bridging.

    If you have loads at one end, with the switching required at the other, you could always consider using a Wiser at the load end, and run a standard single-mode fibre ethernet link across the 10kms, and run a PC, iOS (Apple) device, etc for control at the switching end.

    This way you could also do so over the internet rather than an expensive private fibre link if a decent internet connection is available at both sites.
    Although obviously a private fibre link is going to be more secure, and POSSIBLY more robust than internet connections (if reliable internet is a problem in your area).
    Single-mode fibre can usually span up to 60-70kms or more with the right equipment.

    Wireless/Microwave is also a possibility if you have line-of-sight and the right equipment, although 10km is seriously pushing the limits of that technology with any reliability. This solution would also be weather dependant over great distances, so probably not ideal.

    Why not just run a microwave link.

    what kind of latency are we worried about here ?
