Time to pull some more fiber (lemmyonline.com)

Since, my doctor recommend that I put more fiber in my diet- I decided to comply.

So.... in a few hours, I will be running a few OS2 runs across my house, with 10G LR SFP+ modules.

Both runs will be from my rack to the office. One run will be dedicated for the incoming WAN connection (Coupled with the existing fiber that.... I don't want to re terminate). The other, will be replacing the 10G copper run already in place, to save 10 or 20w of energy.

This, was sparked due to a 10GBase-T module overheating, and becoming very intermittent earlier this week causing a bunch of issues. After replacing the module, links came back up and started working normally.... but... yea, I need to replace the 10G copper links.

With only twinax and fiber 10G links plugged into my 8-port aggregation switch, it is only pulling around 5 watts, which is outstanding, given a single 10GBase-T module uses more then that.

Edit,

Also, I ordered the wrong modules. BUT... the hard part of running the fiber is done!

Was thinking of going the same route, as my employer threw away a couple of good working 10G optic sfps, but alas, only 1 of my 2 netgear switches supports sfp+ modules. (Couldn't even get a simple 1.25G utp sfp to work in it)

I have a 100$ or so mikrotik here in the office, which is on the other end of that fiber. Its not at all picky on module choice.

Also- neither my brocade nor unifi aggregation switch are picky on modules. They have so far, taken every module I have tried.

The Intel X520-based daughterboard for my r730 though, its extremely picky. Gotta be intel/dell.

The Netgear 324 I have is picky (seems to support only SFP, not SFP+, the 724 was gifted and accepts the 1.25G UTP module. I also have a Cisco 3560 24P with 2 sfp ports. No clue yet if that works correctly and how much power it'll use, but I can test with a short fiber cable I have (when it's not damaged to much) Also, no clue yet how I'd route the fiber trough the house, 4 floors up, 1 across and then 1 down. (about 15-20m) I have cat6 throughout the house, but that's a tad less fragile.
