Setup for my FTTH home network wiring I solved this issue successfully.
Hi Everyone, I recently had fiber optic installed at my home and connected it to my provider's modem (Telus T3200M). I'm planning to set up a home network using fiber, mainly for DAC, but my router only supports one SFP+ port. I'm considering using a microtik CRS305-1G-4S+IN as my switch, but it only has a single SFP port. I'm thinking about wiring the incoming SFP into the microtik, connecting my other computers to the switch, and then running a fiber line from the switch to the optical port on my modem. I'm new to networking and fiber, so here are my questions: 1) Will this actually work? I'm worried the router might not be able to tell the difference between traffic from outside and internal devices. I also want to make sure my computers get proper IP addresses. 2) Is this setup safe? Could my computers be directly exposed to the internet, possibly bypassing the router? 3) My internet speed is 1Gbit, but the router only shows SFP support. Would plugging it into the microtik's SFP+ port still work? Thanks for your help!
Looking at it differently, why opt for a more intricate configuration instead of a straightforward router and Ethernet connections? A gigabit link would work equally well and save money.
You should talk to Telus about this, because connecting the incoming fiber SFP straight into something other than an ISP-approved modem might break the service rules or cause it to fail entirely. The fiber node and Telus network expect an authorized modem, not a third-party Microtik switch.
Here’s a revised version of your message:
Thank you all for your responses—it really means a lot! I’ve updated the details below. A quick question: Could we use VLANs to separate traffic? With four SFP+ ports on the MicroTik, one could connect the ISP to the router, and another to my computers. Does this sound sensible? According to "Electronics Wizardy," it might not be ideal. The original setup was: ISP → SFP cable → T3200M router → RJ45 → MicroTik Switch → SFP+ → Computers/NAS. This seems logical. My goal was to prevent Ethernet becoming a bottleneck when uploading large files from my NAS to the internet and also sharing with other devices not connected through the switch. However, I realized that even with SFP+ connections, the link speed would still be limited to 1G due to the T3200M’s capabilities. Regardless, this could create a bottleneck. I’m removing the original idea for future reference. Could you suggest alternatives to avoid this issue? It might become costly quickly. If so, please guide me toward the best options. I really appreciate the MicroTik because it’s fanless and affordable. The lack of a fan is important for my setup, especially since I’ll be working from home and need quiet operation. I understand that. I’m planning to build a NAS and a separate workstation, wanting the latter to access data directly from the NAS. I also want to keep them separate to manage heat—my workstation will be a 2950x with dual 2080 series and a 1060. I’m handling datasets over 10GB, often around 27GB. Moving all data to the NAS would make a big difference. I’ve been looking into connecting directly to the switch, and there’s a forum discussion about this. If you’re open to it, I’d appreciate your advice before investing right now.
This appears to be the optimal choice here. You can upload quickly and efficiently while keeping costs low, and it’s straightforward to operate. What rate do you currently receive from your internet provider? You’re unlikely to exceed 1gb/s regardless of the plan, and if you’re billed above that, they’ll supply gear enabling full-speed access (though this is uncommon in residential setups). The device doesn’t seem to include an SFTP port; it appears to route traffic elsewhere on the premises. Additionally, it’s limited to a single Mac, functioning more like a switch for media distribution.
You asked how your quote was divided when responding to different sections. I can include the quotes if needed, but it won’t add a timestamp or mention what you said. Regarding speeds, I’m still figuring it out. I’ve only tried it on my phone since I haven’t built up a desktop setup yet. The wireless AC gave me roughly 300-400 Mbps. I’m on the road for work now, but after returning home I’ll set up my computer and run a speed test. If data from your NAS drives isn’t slowing things down, you should be able to upload and download simultaneously. Assuming the total bandwidth between your router and switch is only 1Gbps, it might slow things if local clients start using the internet and TV simultaneously. Since 2Gbps would meet your needs, would it make sense to add a second switch with an SFP+ port? You could connect the SFP+ to your microtik and bond 2Gbps to the router. Your router already has an SFP port, so it seems like a logical upgrade. It appears the ONT might not be present because its specifications don’t list it, only in descriptions. Some users have ONTs for VOIP or other services, but you’re just using the internet.
Likely not, since all LAN traffic will go through the switches and WAN traffic is capped at 1Gbps. I should consider getting a switch with both 10Gbe and 1Gbe RJ45 ports for other devices. Mikrotik suggests checking with your ISP to see if they allow you to install an SFP on your own switch or router. Try to avoid using the ISP router if possible.
