Fibre and Load Shedding

[FGRL]

So I go and cancel all my vodacom data contracts and get my CISP fibre installed and like an idiot find out last night that when load shedding happens my fibre goes off..... I’m feeling pretty stoopid right now for not realizing that.....

Is there a cheap way to keep my fibre running during load shedding? Like, can’t I just plug in my portable charger and charge it?

Eish....

 

[ArmatageShanks]

A UPS maybe?

 

[Pineapple Smurf]

Yup a small UPS will keep that little puppy going

Are you talking about your router or the fibre connection?

Usually you will have 2 boxes. The ONT that powers the incoming fibre line and the router (with wifi) that distributes the internet over your LAN/Wifi network. So both boxes need power.

The ONT should use around 24Watts and the Router between 12W and 20W, so you need at least 40W for 2.5hours, or 100Watt hours of storage capacity in the battery.

I just had a similar experience at home, where my UPS died after 1 hour running only the fibre ONT. The UPS seems to use power too, just to run.

I actually seem to need about 70Watts for 2.5 hours which is 175Watt hours of storage.

At 12V, that's about 6.25 Amp hours of capacity, but the problem is that batteries are rated for 20 hours and not 2.5 hours. So we probably need double that, or at least a 12V 12ah battery.

A UPS with at least 2 x 7ah batteries should be fine. Generally they are rated at 1000VA or more, but check the manufaturers data sheet to see what batteries are actually included.

I was thinking of connecting to a mini UPS - one for ONT and 1 for Router.

I was looking at this:

Now after reading all your comments I am thinking it’s not a good idea....

This is all so expensive though!

What now?

Do I sound really dof? Cause i am ......

There's a router from your ISP and an ONT from the fibre provider - you can power these devices in your home via a UPS/genset. You have zero control over the actual fibre line. If the UPS/generator at the POP goes down, your link will still go down.

Well I have the problem with ADSL. My router I can keep on with inverter and batteries. But Telkom doesn't have any backup power. So it is useless for Internet.

Or one big one with a splitter:

Try to pour some milk on the fibre line.

Yes for the router get battery backup.

There are a few threads on the forum already about this issue.
Forget the UPS solutions!. Get a proper DC backup power supply which switches in and connects to a battery backup when the power goes off. Why the DC to AC conversion to feed an AC power supply to convert back to DC to feed the devices? A simple DC - DC conversion from 12V to whatever the router needs is by far the better solution.

If it were me and i just wanted to run those 2 items and not strain my UPS battery i would spend R1099 on something like this.

So during loadshedding I am guessing that Century City has some sort of backup which would keep it on?

Thanks so much for this insightful suggestion! I get very confused and having a suggestion like this makes it a lot easier for me!

You would think so. Only way to know is to test it. Find a way to keep your router on. A UPS should work. (just remove the stupid beeeep beeeep beeeep thingy)

Think I’ll skip the milk spilling.....

The light source at the provider end? I'd guess a big installation like that will have sufficient backup capacity for a day or two.
