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).

πŸ”— N/A replaceable (dual LC on the bundled SFP module) depends on the SFP module (2 on the bundled one) Feigee HTOC N/A 5V DC barrel jack ❌

The last two items, while untested, seem to be rather curious.

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:

TODO: add three more devices:

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.
