So I have a customer with a private PTP network built long ago, obviously, with PTP400 links. For years this has worked great and they have been happy. Recently, due to either lightening or another contractor issue, one of the three sites (2 of the the total 6 backhauls) are now dead. I could probably find some ancient stuff and maybe replace these two but I thought now would be a good time to get them into some supportable equipment.
I would like something as trouble free as the PTP400. Throughput is a non issue as they only need about 2Mbs. The main deal is reliability and my desire to not have to jack with the thing due to outside influences be they weather or interference. Basically as close to the 400's trouble free operation as possible. Cost is a factor but not the primary one, yet something above $1000 each side is a non starter. I have looked at the PTP550 which is based on an AC chipset but says it has: Dynamic Spectrum Optimization (DSO)* With Dynamic Spectrum Optimization, PTP 550 systems are constantly optimizing the channel of operation to maximize link reliability and performance. Based on environment the PTP 550 can be set to move or search better spectrum. As a result, customer can get more throughput with limited spectrum in even the most challenging environments I also looked at the ePMP Force series, based on the same chipset. I have used a bunch of these before but not in this demanding (reliability wise) environment. All the Force stuff seem to have a sentence like these: Configurable modes of operation ensure robust adaptivity to both symmetrical and asymmetrical traffic while providing high performance and round-trip latency as low as 3-5 ms. Configurable Modes of operation ensure robust adaptivity to both symmetrical and asymmetrical traffic while providing high performance and round-trip latency as low as 2 - 3 ms. So I guess my question is, for those using these products, is there really a big difference between the PTP550 line and the Force line? They are both based on the AC chipset so while there is maybe quite a bit they can do to enhance that I can't imagine it would be earth shattering. Any recommendations?
