PoE Extenders

There are PoE extenders and PoE extenders...

So far, one was great, one was good, and two were poor:

 

"Gigabit Power-over-Ethernet Extender, PoE Passthrough Switch"

Several of these were bought from Anazon for £75-90 over the last couple of years.

They are not cheap, but work at 10, 100 and 1000mbp at both full and half-duplex.

There is no management capability, nor "VLAN" or "length extension" switches, but it just works:

Sadly there's no real make or model on the device, so I can only go by my previous order or check the picture when re-ordering.

It has optional wall-mounting brackets, which is also handy.

PoE Passthrough Switch, 1 PoE in 3 PoE Out Extender, IEEE802.3af/at PoE Powered, 100Mbps Ethernet, din-rail & Wall Mount

£20 from Amazon, July 2024

Although it's not listed as such, I think the make is "Binardat".

Note that on the bottom, it specifically says it supports 10mbps:

However, when 10mbps devices were plugged in, no traffic is passed, although the LEDs flash like there is activity.

This device was returned to Amazon.

Binardat Outdoor Gigabit PoE Passthrough Switch, 1 PoE in 4 PoE Out Extender, IEEE802.3af/at/bt PoE Powered 90W, 10/100/1000Mbps Ethernet, Wall Mount Waterproof Plug and Play, 1000M OUTDOOR 5 PORT

£30 from Amazon, July 2024

Note, this also says on the bottom that it supports 10mbps.

Again, when 10mbps devices are connected, the LEDs flash, but no traffic is passed.

This device was also be returned to Amazon.

Nvanvmm Replacement 4Port Gigabit POE Extender 1000M 1 to 3 Network Switch Repeater

£15 from Amazon, November 2024

Finally! A cheap one that actually works at 10mbps half-duplex!

Again, doesn't really have a make on it, so I assume it's "Navanvmm", and not sure what it's replacing exactly, other than for me it replaced the 2 crap ones mentioned previously!

It can be clipped onto a DIN rail, but I do not use that function.
