Fibre optic split

[macimaster]

I wonder if anyone could help. I am new to fibre-optic however I am not new to networking. In the next couple of weeks I am getting FTTP installed and I have some outbuildings that I would like to have full fibre speed in as well.

 

I’m just trying to work out the best way to do this. I am thinking of splitting the incoming cable with a splitter box that splits the incoming single fibre cable to 4 double SC connectors. And then I don’t know if possible, but then to have separate ONT’s in each outbuilding?

 

I want to use Fibre cable to extend rather than RJ45. Can anyone help?

You can't really "split" fiber like that. 

 

The connection handed off to you from the CPE will hit a router, then get distributed to your equipment from there. You'll have to connect fiber to your router using an SFP or over a copper-to-fiber media converter, depending on what ports your router and switches have available.

Why? Are you planning to pay your ISP for multiple fiber connections? If so, then the ISP will have to run fiber to each building; it's not your responsibility.

Copper is quite good for even long runs, and might be easier/affordable to set up and maintain.

 

Are your cable runs between buildings expected to be longer than 100m? Is your fiber connection promising greater than 1Gbps?

yes planning on multiple connections, unless I can easily network with network fibre cabling to keep loss at a minimum. 
the speed loss through WiFi and copper is too great as the distance is, yes it’s greater than 100m to both buildings.
 

my connection will be 5gb. Is there a network switch that would be adequate enough instead of running multiple connections?

 

thanks

You need to speak to the ISP on that. Keep in mind each ONT will likely equal its own internet account. So for example if you have your home + 2 out buildings they will likely charge you for 3 separate connections. Also, these would be separate connections, so they will be on their own separate network.

Amazon sells like everything. I sure you can find a place online to buy some.

Umm enterprise users have been using 10 Gbps fiber for years and years. So yeah a switch exists. You can find used enterprise switches online for a fraction of the cost. 5Gbps gear is new, so it might be more expensive. Are you looking just to have 5 Gbps to each building, or are you planning on doing 5Gbps to devices as well? If its just to the building, then I would imagine it would be easy to find a switch. Ive seen tons of some switches would might offer 2 to 4 SFP ports that can handle 2.5, 5, or 10 Gbps. 

 

Also what equipment is the ISP providing? Are they providing a standard ONT or are they providing a gateway?

10Gbit network switches exist specificly for your use case, which have multiple SFP+ ports to connect to other switches.

As an example:

 

But of course such a setup isn't exactly cheap.

For example the UniFi Aggregation switich, which features 8 SFP+ ports, will cost you around 250€. On top of that you'll need SFP+ capeable switches for each building, which will set you back another 150€ for each switch. Then the additional cabling and SFP+ modules and you can already imagine where this is going...

 

The idea of your ISP simply terminating multiple fiber connection to your premise sounds a lot better, where you'll simlpy have your own network and connection for each building, but of course you'll need to find a way for the networks to communicate with each other, if that's what you want. Maybe your ISP can offer you a public IP including a small subnet, but that'll also likely be quite expensive, in which case you might actually want to go the other route and get the expensive hardware.


Either way, it all gets a little complicated and quite annoying to deal with.

Depends where the Op lives. AT&T started offering 5 Gbps and they charge $180 USD. Multiple connections from the ISP will likely be separate accounts. So from the example I gave with AT&T, $180xNumber of building, that can get expensive fast. Who says the OP needs to buy new equipment. Maybe they can get a deal on older enterprise equipment to save some money.

Which is why I said it "sound a lot better", which doesn't mean it is necessarily better.

Yeah who said that? No one. It's an example!

[Needfuldoer]

No need to buy new equipment, not when there's a whole secondary market full of decommissioned 10 gig enterprise gear out there! 10 gig SFPs are a dime a dozen, and switches like the HPE/Aruba S2500 and 3500 aren't all that expensive. (Certainly a lot cheaper than prosumer Ubiquiti gear.)

 

Run a conduit between both buildings, and throw at least a couple pairs of single-mode fiber into it (and a pull string). You shouldn't ever have to touch that again.

So what equipment are they installing? Are you going to have a fiber hand-off? If you're getting a 5Gbps Internet, then the demarc interface would probably be a 10Gbps SFP. Then you can just follow the example above with UniFi switches, run fiber to your other buildings and you're done. If this is consumer Internet, their gear will handle firewall functions most likely.
