    I think most of the cheap SFP+ cards from ebay have Windows drivers, but definitely do some googling of each model to be certain.

    Ordered all the parts on my list. I should have it by Thursday 8/15/19. I am guessing that there will be some kind of light indicator to show if the fiber wires are making a connection.

    Edit: looks like the switch has a set of lights on the side of the box / panel to show if the connections are functional.

    Besides status lights, the switches each have a web interface which will give you more information than you knew was even possible :)

    Well, I tested out the switches and I used a single mode duplex cable and the light on the side lit up. Then after establishing a baseline that the switches function, I connected the six strand single mode simplex cable to the switch and no light. Is there a certain order the colored cables have to go?

    I am really worried that I will have to run a new fiber line.

    Or is is possible the six strand simplex cable will only with with a SPF+ adapter specifically for simplex connections? I.E. I can't double up my simplex strands (group them in two's) and simulate duplex.

    Thanks for any help.

    EDIT: NEVERMIND --- I switched the color pairs on one end and they all work now. So for some reason the colors are switched on the main switch. Whatever. Happy it works. Ready to nail down the office floors now that fiber is verified to work.

    Congratulations!

    The way the modules work, one side transmits while the other side receives, so the way you originally connected them, you had one fiber with a transmitter on each end, and another fiber with a receiver on each end, and no communication could happen.

    A duplex connector is just two simplex with a plastic bracket holding them together at an appropriate position. If you fiddle with your fiber patch cables you will probably notice you can pop the connectors out of the bracket and effectively have two separate fibers.

    Wish me luck, I picked up a couple TFC-1000MGA media converters ($4 !) and took my first crack at buying the proper used optical modules and a test cable just for tinkering and learning more about the ins and outs of fiber. These just happened to be at the local thrift store.

    Super cool! Nice deal. I can't wait to get my office finished so I can start using my fiber line. LMK how it goes and take a picture and post it please!

    Yeah just going 1 meter for starters, to see if everything works, and then decide what to do from there. I read that using media converters drastically increases risk of failure (more devices in the path = more devices/power supplies to fail), but for $8 for two units and another $40 for modules and optical cable just for a little learning it seemed smarter than a giant purchase of something like an optical switch to start with.

    After 25 years of marriage, the wife has learned when she asks "what are those are for?", and I say "just something to play around with".....that there is no actual purpose for the purchase and it's probably going to my office to never be seen again!

    Update on office build. Floor is installed and all cables are punched through the floor and the floor openings are sealed with closed-cell foam. Wall / window frames are up and mostly set. Windows came in today.

    I'll be working on terminating the Cat 6 lines once the outside wall is up and windows are in.

    For the outside IP cameras I picked up two EmpireTech PFA130-E Water-Proof Junction Box Brackets -- I'll be painting them black to blend in.

    The IP Cameras I will be running on the East and West wall is EmpireTech IP Camera Black IPC-HDW5231R-ZE

    EDIT: Quick slightly off topic question: I will be running an underground fiber cable to my garage in the next couple of weeks. I was NOT planning on running CAT6 due to lightning risk. The cable will be in a conduit (est 18" deep).

    Any conduit recommendations?

    Any junction box recommendations for the house and the garage? I want this to be waterproof but accessible.

    Thanks!

    Technically, and mathematically, yes. That said, in my 20 years in enterprise networking, those devices are amongst the most bomb-proof gear I've used. I think I had 1 fail at some point. I've had some failures with them becoming unplugged (usually a simple barrel DC power plug)... I have a few in production that were made when I was still in school. Allied Telesis (formerly Allied Telesyn) is a well-known brand in that market.
