I see how you might say that… but we had established the SFP kits back in the 
PTP 650 days. This was really because there were suspect-quality SFP modules 
floating around, and we wanted to ensure that water ingress (i.e. 
weatherproofing) was being done correctly when the fiber connections required 
extension from the body of the radio. 

This will be changing in the near future in that we will start selling the 
extended gland separately (at a more reasonable price), and no longer require 
an “entitlement key” to enable the SFP port. In the end, this means that you 
can buy your own SFP module and use it as you like. 

Hope this might help change your view.

Unfortunately, Cambium nickel and dimes you to use the SFP port.

The unique thing about the 450m is the SFP port. The concept would be fiber to 
each radio for data, and this box would be for power+sync. It would include the 
GPS antenna in the box, etc. Essentially you'd provide bulk power to this box, 
run a short CAT5 jumper to each radio for power/management, and a strand of 
fiber down the tower for management of it all. That would get you management 
into each of the 450m's and power and sync. 

For data, you'd put a SFP in each of the 450m's and run that down the tower via 

At the bottom, you'd just have a fiber switch and a bulk power source. 

This box would do double duty with small clusters of 450i.

Could be fine for a tower-top DC+fiber fed injector(+sync)-switch. Same concept 
as the UBNT edge thing. Consider that something like this would need a 10G 
uplink if you're going to be powering and timing a 450m cluster. You're 
probably going to want at least 500Mbps to each sector. So only a 1G pipe up 
the tower isn't thinking towards the future. Something I think a product like 
this would need is an integrated voltage regulator. And wasn't something 
similar kicked around in the past? Instead of a switch, make it a multi port 
injector+sync with media conversion. A strand or pair per radio. Or even CWDM

It would be awesome if you could ever develop products with switches inside, I 
know you have a (Cisco?) preference but other's dont. 

I would have purchased lots. I hate that I have to use a separate switch so we 
moved away from packetflux for new deployments.

I'm assuming you mean includes switch+poe. 

I'm in the process of working on something specificaly for the 450i/450m with 5 
ports and sync hardware all in one box (+1 SFP port), mainly designed for tower 
top mounting. Not far enough along to say when it will ship, or even if it's 
ever going to see the light of day. 
Any other solution you look at, you should make sure that whatever solution you 
find will support at least 70W per port, and all 4 pairs. Neither the 450i or 
450m really care about polarity, unless you're doing sync, and then only on the 
450i since the 450m does the new cambium sync only. 
If you can live with separate poe box, of course the packetflux 
powerinjector+sync powers 450m's really well. There will be a version which 
does medusa sync out sometime soon, it's a sure thing, just we don't know 
timing yet.

Good morning, 

Looking for an all in one, but reliable, power source for 4 - 450m aps per 

I have heard netonix a few times but I have also heard about some issues with 
these devices and their support not being that great.
