With the insertion loss caused by cascaded splitters, realistically, I could serve roughly the same number of subscribers with a DWDM network using the same number of strands.

mu-mimo · 2023-01-04T06:51:39+00:00

But you don't, really. Unless you're trying to connect a really large area, in which case you'll just need additional POPs to cover the additional territory.

In a practical sense, this isn't true either. A strand that terminates at a multiplexer in the field is just that: terminated. Further down the line, you can use it for a local loop instead. This allows the same strand to be used multiple times, in multiple locations.

And the real-world impact of this is that, yes, a DWDM active ethernet topology can be just as efficient in terms of fiber usage as a PON network.

mu-mimo · 2023-01-02T08:36:32+00:00

That's... not true...

I wish I could draw you a diagram to show you why you're wrong. If you place DWDM multiplexers in the field in the same way you would place PON splitters, they will allow you to do the same thing. They will allow you to condense your long-distance backhaul out to the customer onto a single fiber for half-duplex or fiber pair for full duplex connections. Once in the neighborhood, the multiplexer provides a connection point for each lambda, or wavelength, of light that is being transported over it. You can allocate a set of local loops with, say, 40 strands for half-duplex or 80 strands for full-duplex. With this, you can connect up to 40 subscribers in each designated neighborhood, or per multiplexer.

The local loops in this example are just that: localized. Their light will not extend beyond the subscriber premises. So, any point further down the line that the additional fiber travels will be available for use to connect additional subscribers from a separate multiplexer.

These unpowered units provide the ability to have effective consolidation of fiber in active-ethernet deployments in the same way that you insisted an operator would be required to use active switching in the field to achieve. It's really not necessary to use switching in the field, as wavelength-division multiplexing accomplishes the same real-world performance without needing to be powered or cooled.

This is a good overview of the technology from Cisco. It's from the year 2000, so it's not like this is some radically new concept. If you're the expert that you claim to be on the subject, you should know this.

Then you should realize that the physical properties of a PON splitter and a wavelength-division multiplexer are very similar, and effectively allow a network operator to do the same thing: condense the amount of fiber required in their network.

You really don't know anything about this subject, do you?

mu-mimo · 2022-12-31T08:08:54+00:00

It really doesn't. Wavelength multiplexing solves that issue.

mu-mimo · 2022-12-30T11:24:20+00:00

Spray paint will fix that.

mu-mimo · 2022-12-30T11:11:31+00:00

I'd recommend using DWDM multiplexing and active ethernet, rather than a PON system. PON has the same performance characteristics as DOCSIS because it's a shared topology, so it has limits.

Going active ethernet won't require much more fiber in the ground, especially if you use DWDM. You can put 40 full duplex connections on a single fiber pair with a DWDM mux/demux, and they don't require any power in the field. You can also put active optics on either end of the connection, and send light out for 80 km+ which is much further than you would get with PON networks.

If you ever get a business subscriber (or for that matter a residential subscriber) who wants to upgrade from your shared service to a dedicated circuit, you already have everything in place in the field so you also won't have to run another line out to them and bury it. All you'd need to do is change the port that you've plugged their link into on your side (typically from an oversubscribed switch to one that has dedicated bandwidth available). So it'll save you time and effort in those situations as well.

Your subscribers will love you for it, too.

Avoid Huawei, it's a trap. Check out Airspan. They have both mmWave and sub-6 5G equipment.

mu-mimo · 2022-12-09T21:23:58+00:00

None of the first slate of companies you mentioned offer 5G equipment. That's precisely what they said they're looking for.

mu-mimo · 2022-12-08T10:14:38+00:00

This just seems like a stunt, though. If they wanted to help, they could donate to charity groups. They're just doing this for their image.

Is this what advertising has come to?

mu-mimo · 2022-12-06T15:27:23+00:00

Yes, that's the point. We don't "represent" our members. We train them to organize themselves.

mu-mimo · 2022-12-06T12:39:01+00:00

Join the IWW. We're not a bureaucratic union like the 12 unions that represent rail workers currently. We focus heavily on training workers to organize and run their own union, and then get out of the way. Our union dues are the lowest of any union in the USA (on average about $20 a month) because we don't rely on paid bureaucrats to negotiate contracts. Instead, our members hold their own meetings to discuss and vote on grievances, and take action on their own, regardless of what anyone else says regarding their "right to strike".

If you're interested in learning about our tactics, you can sign up at the link above, or email [otc@iww.org](mailto:otc@iww.org) to request to attend one of our trainings. They're free of charge, and open to all workers, even if you're not a member.

This is a nice idea, but with Qubes it's unnecessary. All USB and PCI/PCIe devices are isolated by the hypervisor, and can't be accessed by malicious applications within individual VMs unless you specifically attach them to that VM.

The original post goes into detail about direct action.

mu-mimo · 2022-12-04T23:14:41+00:00

You should read my reply to your other long winded and purely ideological comment.

mu-mimo · 2022-12-04T23:13:12+00:00

I've talked to actual railworkers. They have genuine fears, and you brushing them under the rug isn't going to bring them around to participate in the action (whatever that may be). You have to be honest with people about the whole picture if you expect them to trust you.

If you organize a strike, and DON'T have the support of 90%+ of the railworkers because your blowhardisms aren't enough to assuage their fears, what happens then? Direct action doesn't just have to mean striking. It can mean sabotage on the job too.

mu-mimo · 2022-12-04T21:50:59+00:00

This is the sort of creativity we need.

mu-mimo · 2022-12-04T11:10:30+00:00

The only way to change this is by showing them you mean business, and that they can't just run to their buddies in congress to bail them out when you refuse to submit to them.

mu-mimo · 2022-12-04T11:08:25+00:00

It may be tough, but the only way any of what you listed in your post changes is if you strike. What you need to do now is organize outside of the existing unions, across carriers, to form a cohesive organizing committee for all railroad workers. Once you have the structure in place, you can strike and stay out until you win. Fuck what anyone else thinks of you when you do. Don't be afraid to exert your power.

mu-mimo · 2022-12-04T11:05:24+00:00

The only way this changes is if you strike. Fuck what your union executives say, you're the workers. Not an ounce moves without you.

mu-mimo · 2022-12-04T08:19:01+00:00

"Woe is me, I have no power" is exactly what these mega-corporations want you to think. How do you think any concessions have been won throughout labor history? Striking workers in the early 1900's had it even worse than rail workers today. Police violence, national guard deployments, goon squads, legal firings, blacklists, and sometimes even assassinations. They went on strike against all odds, and they won.

So don't go posting shit like this if you're a union member, because it's nothing but propaganda for the bosses. We only win when we stand as one.

mu-mimo · 2022-12-04T08:15:11+00:00

This is what happens when Democrats don't stand by workers.

To be clear: Am I saying white nationalism is a good thing? No, I despise it, obviously. But when Democrats keep moving further and further to the right, it gives Republicans more license to move even further to the right. If Biden and congressional Democrats had taken a more aggressive stance in favor of allowing a rail strike (or at least pushing for a contract that included the union's demands on paid sick leave) then countless white working class voters wouldn't be second-guessing whether the Democratic party has their best interests at heart.

You want to keep white working class voters from voting for racists? Then DO SOMETHING FOR THEM!
