POE Midspan Distance
If a POE Midspan is placed at 100 Meters can the ethernet cable on the other end be utilized for an additional 100 Meters? It's my understanding that it can not, but if anybody could provide a definititve answer I would appreciate it.
Thank You.
No.
Midspans are not extenders, they are just power injectors.
If you put a PoE *switch* at the 100 Meter point you could extend the network another 100 meters.
Then what use would it be if it only extended power and not data?
It doesn't extend the power, it's just a power injector. It will allow you to utilize a normal switch while powering the cameras over Ethernet.
A midspan is basically a multi-port PoE injector. It allows you to operate PoE devices on a switch that does not support PoE.
They're more common in upgrades of existing systems, as in most cases a PoE switch is cheaper than a switch+midspan setup.
Thanks, that's what I thought. I was reviewing this network diagram in a poorly written RFP and it had be second guessing my self.
Sorry, I was thinking of a POE extender
If you wish to extend the distance by 100 meters AND you do not mind having a small POE powered device placed at the 100 meter mark on the cable, then our OUTREACH Max will do the trick. You absolutely can extend by 100 meters, and more, and the "next" 100 meters is just the same as was the first 100 meters.
If you do not want to have a device in the middle, you can use LONGSPAN, which is an end to end device.
