Fibre Fun

[pagelad]

One of my primary schools has fibre running from the main comms cabinet to comms cabinets A and B througout either end of the school. This has all worked fine until yesterday where one of the fibre units went off.

 

I unplugged the converter from comms A and tried it on the main comms cabinets power (they both have identical converters) and it works. Yay i thought and went out hunting for a new power supply, unfortunately it seems the converter uses at 5v 2.4A adapter which i cant find anywhere!

 

Now to get them back online im a bit confused.. should i percivere and try and find an adapter or do i just get a new fibre converter? If i do are there different types and what should i look for?

How much will a new converter set you back?

What about contacting the manufacturer?

[pagelad]

Contacting them was the first idea but there isnt a brand name anywhere on the device

 

It literally just says "Fast Fiber Converter" , underneath it just has printed the pibre size and wavelength so no joy on that.

 

I havent been able to find a power supply to go with it, i cant seem to find anything that runs at 2.4a , i picked up a multi converter unit and that did the correct voltake but its ampage was too low so the device wouldnt function properly

This do you? (5v 4A)

Forgive my cluelessness but if i use this on a device that only needs 5v 2.4a what will happen?

[powdarrmonkey]

You need to get the voltage exactly right, and you need to equal or exceed the current (A).

 

Voltage is like a push - it's how much the supply pushes onto the device. Current is like a pull, it's how much the device pulls from the supply. So as long as your supply can supply at least that much current, it won't melt. Whereas if you mis-rate the voltage, you'll either melt the device if there's too much, or get really weird behaviour is there's not.

 

So if your specifications are 5v, 2.4A, that supply will be fine. Just make sure you put the tip on the right way round so that it has the right polarity (almost certainly it should be centre-positive).

Nothing bad. It just means the adapter can provide 4 amps. The converter will just draw the current it requires.

I have a 5v 2.5A one here if you want it? center pin + .

any use just pm me.
