The platform will be available all the way down to 6 GHz. Watch the TBW videos from the shows to stay current on the platforms out there. The Trango interview is three months old now. :-)

Based on previous experience with the higher end Bridgewave products (1Gbps bridges) which have SFP ports, they do have a software/firmware option on the same platform to enable OC-3 and OC-12 functionality but very few carriers ordered the option. As described by Bridgewave sales a tiny fraction like 1-2% of units sold or less. If people are buying PTP microwave gear in 2016 for short range use (24 GHz) it's all Ethernet.

Then because of this, there were a lot of 'waves' fiber channels available, as in LH transport, for 2.5g. Today due to cost, ROI and popularity 2.5g is fading into the background in favor of SFP+. Getting back to, arm chair quarterbacking the Trango product, I can think of a couple of reasons why they might have choosen 2.5g SFP module slot, considinger 1G/2.5G modules use the same Slot, chips etc, and SFP+ are not necessarily 1G/10G , also realizing their background with TDM it is quite possible that this product has a shared heritage with another of their TDM radio, or at some point in time (it may possibly be even now) it was intended as wireless OC48 transport. :) Faisal Imtiaz Snappy Internet & Telecom 7266 SW 48 Street Miami, FL 33155 Tel: 305 663 5518 x 232 Help-desk: (305)663-5518 Option 2 or Email: [email protected] <blockquote> From: "Eric Kuhnke" < [email protected] > To: [email protected] Sent: Monday, June 13, 2016 9:49:53 PM Subject: Re: [AFMUG] Trango StrataPro Xi <blockquote> Yeah, sure, if your design goal is to make your L3 backbone harder to troubleshoot and more failure prone in chains of non-redundant devices. I suppose I could put a 48 port 1000BaseT switch in front of each router and put the microwave PTP linked OSPF /30 BB interfaces each on their own vlan, with one 10GbE from router to switch, but I'd be silly to do so.

If people do layer 2 over $6,000+ microwave for backbone links between two POPs, that is a really bad idea in my opinion. WISPs love to build layer 2 clusterfucks because a lot of small ones start with basically no OSPF or BGP knowledge. Show me a real router platform that is in common use that supports 2.5 Gbps SFP (not SFP+ on a rate limited port).
