Grid's fiber optics hardware notes

Introduction

This is a small note I'm making to tell about my experience with media converters, fiber optic cables, etc.

Things you'll see here are quite affordable as I won't be able to test them otherwise; some of these details are applicable for home use. Some of these details aren't applicable whatsoever.

Disclaimer

In no way do I claim competency in telecommunications, or anything else, for that matter. In fact, the tests I'm doing are (proudly) conducted on the armrest of a couch in a flat I'm renting.

Take the information I'm providing with a grain of salt; a can of paprika works as good as a grain of salt, if not more. What I'm trying to say is β€œdon't rely on this information for your final decisions; I'm doing my best to check the information, but would prefer to have the lack of responsibility”. Thank you.

You're welcome to add information, but please add it in a separate category here so I can check it from the couch.

Devices

Media converters

Power inputs in HTB-GS-03B and HTB-GS-20B are compatible: 5V DC barrel jack with anode (+) inside and cathode (-) outside (feels like a breath of fresh air).

The Ewind adapter may be cool at home or office, providing significant communication speeds.

I'm not sure the Xicom adaptor reaches a gigabit on large enough distances, but it's worth testing. It's important to remember that physics interjects to cap the maximum distances:

Maybe it'll be easier to set up a group of media converters as a module:

There are also versions without a case:

Rack-mount media converter chassis

Sometimes, i.e. on distances larger than a typical building, you can expect to need a multimode fiber to transfer the information quickly enough. While adding more media converters in the middle should be possible, inserting many individual repeaters would be harder than installing a multimode cable for a long time.

I expect the large distance issue can be solved using the switch and rack assemblies shown here; however, I haven't had a chance to test it.
