Split fiber optic cable
Split fiber optic cable
I’m curious if someone can assist. I’m new to fibre optics but familiar with networking concepts. Over the next few weeks I’ll install FTTP and need full fibre speed for several outbuildings. I’m considering splitting the incoming cable using a splitter box that divides it into four double SC connectors. I’m unsure about setting up separate ONTs in each building, but I’d like to use fibre cables instead of RJ45 connections. Any advice would be appreciated.
You can't simply divide fiber in that way. The link you received from the CPE will reach a router, which then sends it to your devices. You'll need to link fiber to your router via an SFP or use a copper-to-fiber converter, based on the ports your router and switches support.
Why are you considering multiple fiber connections? If yes, the ISP will need to lay fiber to every building—it's not your job. Copper works well over long distances and can be simpler or cheaper to install and maintain. Are the cable runs between buildings longer than 100 meters? Does your fiber offer speeds above 1Gbps?
You're considering several options for your network setup. Planning for multiple connections is good, but you mentioned the loss through WiFi and copper is too high—especially over the distances involved. A 5GB connection sounds solid, but a network switch might be more efficient than running many cables. Let me know if you'd like help evaluating switches or alternatives!
Discuss directly with the ISP regarding this matter. Remember each ONT usually corresponds to its own internet account. For instance, your home plus two office buildings might result in charges for three distinct connections, each operating on its own network. Amazon handles everything seamlessly. You’re sure there are options online to purchase equipment? Enterprise clients have relied on 10 Gbps fiber for many years, so a switch is definitely available. Used enterprise switches can be found at a lower price. 5Gbps devices are newer and may cost more. Are you aiming solely for 5 Gbps within each building, or also connecting devices? If the focus is only on the building, locating a switch should be straightforward. I’ve noticed many switches offering 2 to 4 SFP ports capable of supporting 2.5, 5, or 10 Gbps. Also, what equipment does the ISP supply? Are they delivering a standard ONT or a gateway?
Network switches supporting 10Gbit speeds are tailored for your needs, offering several SFP+ ports to link to other devices. For instance, the UniFi Aggregation switch with eight SFP+ ports costs approximately 250€. You'll also need compatible SFP+ switches for each building, adding around 150€ per unit. Additional expenses include cabling, modules, and more. The ISP’s approach of ending multiple fiber connections may seem simpler, giving you a dedicated network per building, but you’ll still face challenges in connecting these networks. Alternatively, a public IP with a small subnet could work, though likely at a higher cost. Either option adds complexity and can be frustrating to manage.
It varies by location where the service is provided. AT&T introduced 5 Gbps plans costing $180 USD, and using multiple connections from the same ISP might require separate accounts. Based on the example with AT&T, expenses can quickly add up if you multiply the rate by the number of buildings. It seems the OP doesn’t necessarily need to purchase new gear—older enterprise equipment could offer savings.
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.
What equipment is being set up? Will there be a fiber connection handover? With a 5Gbps internet connection, the demarcation point might be a 10Gbps SFP. You can continue the approach shown earlier using UniFi switches, extend fiber to other facilities, and you're finished. If it's consumer-level internet, their devices will likely manage firewall tasks.
