I’m currently in the process of spec’ing some backhauls, and we were looking into radio’s that are capable of at least gigabit unidirectionally. We landed on the PTP820c because of it’s 4+0 option, which in 15Ghz would net us over 3 Gbps of aggregate throughput. However, we were planning to start with a 2+0 deployment, with the intention of moving to 4+0 down the road.
Where we ran into trouble was discovering that we would need to use a LAG configuration combine multiple Gigabit ethernet feeds, rather than a single Fibre to an SFP+ port or something similarly sensible. We aren’t overly interested in making a compromise on this feature, so we are wondering what our options are.
So my questions are:
Can a 820c, in a 4+0 configuration, work with a single fibre to each radio? The total throughput is 1600/1600Mbps, equaling the predicted 3.2Gbps with two radios. So correct me if I’m wrong, but that’s effectively 800/800Mbps, per radio. Can a 1Gbps fibre to each radio, work in this situation?
The PTP850 offers a 2+0 configuration in certain frequencies. Is there a roadmap for the PTP850 to get a 4+0 configuration? The SFP+ port of the PTP850 is what is appealing about that radio.
So any help or advice from Cambium or the community would appreciated.
