There are fiber cables that comes with built in low voltage wires for poe
applications.

You run both. CAT5 to carry just the power and fiber to carry the data. We
just did this exact thing with our Trango APEX 18ghz radios at our FM repeater.
Worked perfectly. (Of course, that radio was made to handle fiber already, so
it was pretty easy).

Yeah. How do you run poe over the fiber?

Is using fiber-optic cable out of the question?

Thanks Mike,
The change to 10 meg half doesn't help. In fact, most devices won't
connect
at all then.
The worst part is that the most expensive gear is most effected by
this! ug
I have installed ferrite beads that do indeed help. Apryl can get
you the
contact info and part number. 509.982.2181
The shielded cable from Shierene just came in. And I have
permission to
move to the other side of the building. When the snow melts and the
ground
firms up I'll rebuild the entire site. The radio station has a new
transmitter since I first went into the site and another tenant
recently
left. I have more location options now than I did before.
Yesterday I did some testing with a Fluke DTX. It's a crazy meter.
Checks
just about everything. As it well should for $7000. Know what it
doesn't
check very well though? Inductive RF. grrrrr There is one test that
showed some problems though. It's called an inductive pulse.
Readings at
another tower I have (and the tech support guy at Fluke) were 0.
This tower
had a reading of nearly 3000!!!!! Fluke is supposed to find out
what an
acceptable level would be and send that info to me. I've not heard
from
them yet though. The tech's guess was around 30mV.
I did think it strange that when I tested my cable with a volt meter
(one
end to ground, the other to the connectors on the cat5) I was
picking up 2
to 3 volts on each pin. That pretty well seems to line up with the
3000mV
reading from the fluke!
This site has always been a source of grief for me. Must less
reliable than
nearly any other I have, no matter what equipment is used. I always
thought
it was due to all of the other operators in the area (one's been
fined by
the FCC for using illegal amps etc.) doing silly things. Though
nothing
THAT bad has ever showed up on my analyzer. I always thought it was
something that only the customer end could see (couldn't find that
on the
analyzer either though). Maybe my problem has always been the radio
station
stuff. Wouldn't that be great? FINALLY, a network reliable enough
to allow
me to take a vacation. grin
laters,
marlon

Hi Marlon,
It looks like you are on your way to solving this. To get by until
then you
might want to try locking the Ethernet side to 10MB 1/2 duplex. FM
radio
runs around 100mhz at high power levels, well so does a 100MB Ethernet
connection, it communicates at 10mhz. 10MB 1/2 runs at 66mhz I
believe.
Fixing it is really black magic however. Sometimes grounding helps,
sometimes it is better without. Many have placed the cable in
conduit, with
mixed success. I would be very interested if the ferits help, we
have tried
a few with inconclusive results, but have not found a quality unit
to test
with either.

Hi All,
I think we finally have this all figured out. Now I just have to
figure out
how to fix it.
