what's the cost of these radios? On 6/9/2016 4:35 PM, Eric Kuhnke wrote:Can I ask what was the reason for the decision to go with a 2.5 Gbps SFP cage instead of SFP+? I do not have a single router in any network I support capable of native 2.5 Gbps SFP. Such an interface is incredibly rare in layer 3 IP network deployments.If it had an SFP+ interface it would be trivially easy to software rate limit a 10GbE optical port in a router (such as a WS-X6704 card in a Cisco 6500/7600 platform, or a Juniper PC-1XGE-XENPAK) to 2.5 Gbps FD and assign it an appropriate OSPF cost somewhere in between the cost metrics currently used on 1Gbps and 10Gbs interfaces for router-to-router backbone links.If the radio's interface will function at 2.5 Gbps with a standards-compliant 10GbE SFP+ (/not/ one of the special weird 2.5 Gbps FC SFP) on each end of the link, please disregard everything I just said above.On Thu, Jun 9, 2016 at 2:21 PM, John Seaman <[email protected] <mailto:[email protected]>> wrote:Hello and thanks for the questions. The StrataPro does have one 2.5 Gbps SFP cage (along with 3 other GigE ports), but so far we have not qualified a suitable 2.5 Gbps SFP. That is something we are working on. The Xi model is capable of 2 Gbps FDD (4 Gbps aggregate) so that currently requires using 2 of the ports to achieve. Going to 4 Gbps FDD requires two pairs of radios, in MIMO configuration so you would be using 2 ports on each of the radios. Regarding keys, the Si base model allows 500 Mbps FDX, and there is a key that takes it up to 1 Gbps. The Xi model comes with 1 Gbps FDD capability, with a key that opens it up to the max 2+ Gbps. Yes, AES-256 is an optional key. These are the only keys involved with this product. Given the capacity of 1 Gbps and 2 Gpbs on these products, 1 MB packet buffer should be more than sufficient since they can transmit at Ethernet line rate. Let me know if any other questions, or feel free to hit me off list.

Larson <[email protected]> wrote: So I’m checking out the new Trango StrataPro data sheets… The Xi model appears to do 4Gbps full-duplex.. but no 10G SFP+.. So I’d have to use all three SFPs, and one copper gig to get it? Other notes: it appears they’re keying it up.. so you get to pay extra to unlock capacity to 1100Mbps and again to unlock max capacity to 2200Mbps. Oh and if you want AES-256, you get to pay again. The 1MB packet buffer.. seems low. Anybody else have any thoughts? Anybody got one yet? -c
