If it's 23awg cat6, with two wires on each polarity at 100m you'll see some 
drop though.

  Say the router takes 250 mA
  Say you are using 16 ga wire
  Say you are using 2 feet of 16 ga wire. (couple feet) 
  .008 * .25 = 2 mV

  Yes, put in 60 volts in  and get 59.998 volts at the Tik.  

  Not a very effective way to drop some voltage...

  If you put 60v on one end and run even a couple of feet off you're not 
getting 60v into the Tik is my point.

    Talking adding resistance via a length of wire.  My point is it takes a 
long piece of copper wire to get any appreciable resistance.

    10 or 16 gauge for a Mikrotik?  I guess you want that wire to stay ice cold.

      That would be a lot of wire.  
      1000’ of #10 wire has 1 ohm of resistance.  
      1000 ‘ of #16 has 4 ohms.  

      How much current are we talking?

      Or some built in resistance - like a length of copper wire :)

        I'm not an EE, but wouldn't something like a 1w 10ohm resistor in 
series with the fiberbox solve this?

          I've got a design that uses a Mikrotik Fiberbox Plus as pretty much 
an SFP+ holder for a TiBit XGS Gpon module.  Mikrotik says Max power is 57V. 

          I have a power design using a DRS240 that has max power of 57.6V  on 
vBoost.  

          Any thoughts on the real magix smoke release point on a Mikrotik?
