Are there 2.5GBase-T SFP+ modules?

Have you tried some regular gigabit injectors and failed, or just can't find any rated for 2.5g? An injector is just an extra set of ethernet magnetics with the center taps connected to power. I don't have my APs yet, but in theory the gigabit ones should work if the cable run is well short of limits. I have cat6 throughout which should help with that as well.

Engenius sells "proprietary passive" PoE injectors too, so at compliant shouldn't be a requirement as long as it's 56V with enough current.

They'll impact negotiations. All my ubiquiti injectors have failed down to 100mbps, for example.

MA-INJ-5-XX: Meraki Multigigabit 802.3at Power over Ethernet Injector (XX = US/EU/UK/AU)

Multi gig POE injectors certainly exist.

30 watts comes up a bit short for some newer APs
Yes I had a feeling the Cisco catalyst 9000 series and the Meraki MR45/MR55 were rather power efficient especially given all the radios they run.

If anyone is interested, Amazon has the 4x4 version of these listed for $199, but they are backordered. I bought some more to blanket the house in AX goodness. I have plenty of attic space to run wires for new AP locations.

Any recommendations on how to determine e where to put these other than a best guess kind of thing? Is there an app that can be used to optimize positioning for coverage?

Without the big boys tools it's more a matter of sticking an AP in a location and seeing how the coverage is.

Impressively large house if you need multiple APs

It is a large house but two AP’s cover a majority. Just want more even coverage and some outdoor spill of Wi-Fi.

I am hoping ‘ax’ better sensitivity will allow my place to work better on one access point instead of 2, some reason in my old setup the roaming is bad.

Anyway let’s see if ax is much different or has anything to offer, my 4x4 has arrived, have to install it in a central place though and weighing well over a kilogram will need to be actually mounted and cables routed.

since this thread was resurrected, has anyone tried the AQS-107 SFP+ transceiver in an icx 6610 or other ICX 6xxx switch? Does it link at 5/2.5g?


Seems like it could make them work with Ngbase-t ?
Ordered 2 of the Optcore version! Seems like it should work since it links with the switch at 10G and converts internally.

Going to try with a genuine Cisco AIR-PWRINJ6. Seen some reports that NBase-T will link at 2.5 or 5 through a 1Gb injector, just not 10.

I don't understand why they now are creating all these intermediate standards when excellent 10G Intel networking has been around for over a decade.

You can get Intel x520 cards for $50 on eBay if you shop wisely. There is absolutely no need for that 2.5G or 5G Aquantia garbage.

It works better on existing cables (mostly), supposedly lower power, and cheaper. Although your right, 10g is almost the same in those areas at this point.

It is because of Wi-Fi 6 AP's like the EWS377AP they can saturate 1Gb links and business do not want to re cable it is the most expensive part of the Wi-Fi install. 2.5Gb will run over cat 5e at the same distances.

I can think of at least three reasons, all dealbreaking for the people it concerns:
1. 10 GbE does not support Power over Ethernet.
2. There are thousands of metres of CAT5E in schools, universities, corporate buildings etc. that needs something faster than 1 GbE to connect to WiFi access points. Labor cost for rewiring is way more expensive than the price of the equipment.
3. There are a lot of computers these days which don't have PCIe slots:
- Laptops
- Macs
- Mini-PCs (NUC etc.)
(Regarding the last point, yes you can get 10G Thunderbolt NICs for about $150-$200, but my point is mainly that yes, there is a need for that 2.5G or 5G Aquantia "garbage" for a lot of people out there.)

Just a nit-pic - 10GbaseT does support PoE. For example Ubiquiti has a small 10GbaseT PoE switch on the market.

That is interesting. I stand corrected. Thanks!
