Effectiveness of Short Run of Fiber Optic Cable.

[kennyb123]

Attenuation at 1310nm is .5dB or less per km. So unless you’re coiling up kilometers of cable it’s essentially nothing.

I wrote that “coiling has been shown to increase attenuation“. Increase above the number you referenced.

I would be using multimode SX optics which are designed for shorter range in building networks. Or, I would be putting a 5dB or 7dB attenuators on the single mode setup.

Hi @djsina2. I know your post is just a bit back in time, but I wonder if you could recommend such an SFP for my Edgerouter 4. And if possible, is there a matching media converter I could use on the coax out of my Arris SB8200 cable modem? I’d like to break the copper link as soon as possible in my house. I’ve been told that in Florida a good lightning hit can take out a good chunk if not all of a home copper network infrastructure.

You could get these:

For the vendor compatibility you should choose generic.

I'm not sure what you mean about the media converter? The input of your SB8200 is coax and needs to remain so.

Sorry. I meant the Ethernet output.

I was itching to get this done , so I got one of these

It looked good. I also got one of these for the SB8200 side

With the appropriate ST to LC 50/125 um patch cable. Should have it all today.

I would simply add an FMC (preferably with linear power) immediately ahead of the EtherREGEN. I would use a one-meter DAC cable (direct acting optical cable) to connect from the FMC to the ER A-side. The Sonore opticalModule Deluxe v2 has the reputation of being the best FMC for audiophile use, but you could start with the freebie supplied in the AfterDark link below. No other changes or switches needed.:
