18-24 credit hour semesters… and summer courses when available.

Since I knew virtually most of the program going in, course load in general was stupidly easy to manage. But I would not recommend it unless you really know the material/subject matter.

Edit: there was heavy incentive… GI bill pays for 4 years of schooling. I have a few months left of that 4 year period left of my GI bill… But if I didn’t take everything accelerated, I couldn’t get the masters. So I just went full ham on the curriculum.

I technically did… But I had prior experience to my college degrees. Also blew through 6 years of degree in 3.5. Turns out college is piss easy if you already have the real world experience.

Broad statements are misleading.

Ignoring the context of the discussion is even more misleading. In the context of this conversation, ISPs providing consumer connections and obtaining grant money, my statement is 100% accurate.

That’s how you get fiber into a building or between buildings.

You just said multimode can’t do significant speeds at distance, yet claim that buildings separated by distance would be connected with it? That logic doesn’t hold.

Intrabuilding or intrarack Yes, you’ll find multimode fiber occasionally. But even these rare cases are increasingly replaced by single-mode as costs drop and bandwidth needs rise.

Everything else (ISP deployments, backbones, FTTH) Single-mode fiber dominates. I haven’t seen a single ISP deploy multimode for consumer-facing services over a typical network radius (~hundreds of meters to kilometers). The only minor exception is MMF from the building network room to an apartment unit, which is irrelevant for this discussion and would be EXCEEDINGLY rare as most buildings would just copper line to the unit. But even in that case… the 20+km from the head end to the building counts for much more than the 20meters to the unit itself.

For all practical ISP purposes, single-mode fiber is what’s in the ground/on the pole, and upgrades are handled via transceivers, not ripping out the cable.

OM4 multimode won’t push 10gb at 500meters no matter how good your hardware is.

But just because you said it…

and OM4 is suitable for distances up to 550 m

OM4: Supports 10 Gbps up to 550 meters.

OM4 Not specified 500 m* 150 m 150 m
*The IEEE has yet to officially give a distance for 10GBASE-S on OM4 fiber. The distances are decided by the IEEE in 802.3, not The TIA or ISO/IEC cabling standards. Some glass vendors say 500 m, but most are now quoting “up to 550m.”

You absolutely can run OM4 at 10gbps at or over 500m depending on your optics/laser.

But Multimode was never the point of discussion as the whole thread is based around broadband services (virtually none of it serviced by multimode, if any at all) and grant money for rural area coverage. Any fiber upgrade in this scenario will 100% be SMF with no qualifiers. In my past 30 years of IT career all buried and pole mounted fiber is SMF that I’ve ever seen for an ISP. I can tell you for certainty that ever fiber I’ve buried in the past 10 years for several companies has been SMF. I’m not even sure that I’ve touched MMF in the past 5 years even in intra-rack setups, I think I might have gotten some with a government auction win about 8 years ago I wanna say? With costs of SMF at near parity for the cable itself and getting closer every year in the modules… it’s a dying form factor and was never really in use for ISP services to begin with.

The context of the discussion does…

SpaceX doesn’t provide in rack or in-building connectivity.

SpaceX is an ISP. You wouldn’t have an ISP running multimode.

It is true.

Multimode (what I think you’re trying to reference) isn’t used in distance applications at all, it’s only for short in-building links. Anything that your ISP would provide you would be single-mode. Carrier/Backbone is virtually 100% SMF as well. SMF (OS1 and OS2) don’t really have a bandwidth cap. It’s all transceivers not the fiber.

But the point is that fiber that ALREADY in the ground, you can upgrade simply by changing the transceivers. It doesn’t matter the length, SMF/MMF, or anything else… you just get a transceiver rated for the length of run (power of the led/laser, and the optics). The length is irrelevant otherwise as the presumption is that the install in the ground has been shown to work in the past already.

Old standard ITU-G.652 single-mode has been made to push multi-petabit transfers in lab environments. The only change was the transceivers. And to be clear, ITU-G.652 was standardized in 1984. Nobody rips out the fiber from the ground (caveat is that the cable itself hasn’t degraded). You just upgrade the optics/transceivers.

“It’s not the fiber that’s limiting—ITU-T G.652 defines physical specs (dispersion, attenuation), not throughput. Field trials over 96.5 km of real-world G.652 fiber showed 56.5 Tb/s using advanced DWDM and modulation

And upgrading is piss cheap. Just change transceivers.

Same fiber cable that does 1gbps can do 100tbps.

Sure, I will admit very readily that people abuse it…

But when you punish the idealized case… don’t be mad when only the abusive people are left. Rent control doesn’t fix the abusers and punishes the non-abusive owners as well.

I need you to explain why you think it’s bad. What is the harm you’re perceiving.

Building takes $xxxx dollars to maintain. The profits from that building need to exceed that in order for you as an owner to even want to do anything with the building like repair it…

Let’s take an obviously fictitious example of a 2 apartment building that needs $1000 to break even for taxes, mortgage/loan, common utilities, etc.

If one apartment is rent controlled and you’re only allowed to rent it at $250, then the other must get rented at $750 in order for you to just break even on the property.

This would be their logic. And it’s not “bad” logic.

When without rent control you’d see closer to $500 split evenly between both units.

Now obviously you’d see overhead for things like repair and maintenance, but that once again disadvantages the “new” people even more. $1000 might break even, but you need to charge extra for renovations and such. Since $250 unit is capped, that falls all on the “new” owners which may see $950 or even more in rent costs.

Where in an “even” world… maybe $600 each unit.

clearly i either don’t agree with whatever morality you’re waving at or i dont see its application to the situation. dont be lazy, defend yourself. what if you’re right and all i see is that guy attempting a point and you being like, ‘nuh-uh.’ what am i supposed to think.

This is why they ignored you. This is bad faith and disingenuous as fuck it doesn’t take all that much to come to the conclusion of how “new” rented would be subsiding the old ones. You didn’t have to act like an ass. You are allowed to use your brain.

But once in, the new people become the old people and benefit as well.

This simply kicks the can down the road and makes it impossible for the “new” generation to actually get in to begin with which stagnates the whole neighborhood (less new people to come start business, or work jobs that the “older” folks aged out of). In the meantime, units stay vacant, building gets less income overall making it infeasible for the landlord/building owner to actually renovate and fix shit.

Edit:

Without rent control, old people would be forced to move out of the city, taking thier income (social security, pension and what not) with them.

Which is not competitive to actual paying jobs at current market rates typically. The old person moving out to the suburbs where things are more affordable typically means the space becomes available and can be filled with new blood that can go and work which is a much bigger boon for the economy than someone strictly drawing retirement.

“both sides should stop the violence and talk it through”

Hard to have a sit-down talk when one side (Palestine) outright says their goal is to kill all Jews and Christians.
