Rick: Again, I just threw up on the screen in case you were interested in looking at just a couple of core diagrams here just showing you how easy this system is. Here's a standard plugging into a core. I'm going through a structure cabling system, that MPO adapter there, I'm going into a trunk, going out to a cassette module. So, I go from parallel on one side to duplex on the other side, okay? Easy.
All of a sudden, if you remembered the last drawing on the left hand side, okay, same scenario on the right hand side but now, I want to take out that cassette module and I want to hit various different LCs on my switch there. Boom. Pull out that cassette module, slide in that adapter panel and I plug in that harness stop cable. Easy to do, genders are already taken care of. We don't have to worry about that.
There's the scenario again. Here's a strictly ... a duplex link, from end to end. Again, once LC jumper, the same on each side. One cassette module, the same on each side, one style trunk, okay? Works on both sides.
That same link, if you remember the slide again previously. I know this is hard to follow when you're just flipping through slides it's sometimes hard to follow with the diagrams, but this is a scenario where previously, okay, this is a duplex system. Here's what we're really referring to, right?
So now, I have a duplex system. Just say I'm using BiDi, I'm transmitting 40 Gig. Okay, well I need 100 Gig now. I got some new switches in. Boom. Now on each side, my jumpers become MPO based. I pulled those cassette modules out, I put those MPO panels in, therefore I'm utilizing our same enclosures that we already have in our racks, put feed-through adapters in and I'm plugging right in.
No cost, with the exception of obviously the adapters, but no pricey equipment. No conversion modules or anything, okay? The system works. The gender is already taken care of on the MTP trunk regardless of what you're using. Genders are already taken care of on the MTP jumpers. They work, plugging it into the machines as you see, and they work plugging it into the structure cabling system with the same type of jumper.
You can take this jumper, for example, out of the structured cabling system here and you can just go machine to machine and connect it if you had a scenario like that. Again, simple.
Rick: Simple. Again, truly what I think the actual term plug and play means. Four products, the same regardless of what you're doing. Never have to worry about fiber path, never have to worry about gender. No inventory management. Makes everybody a fiber expert. You won't be sitting hours on the phone tracing fibers trying to find out where something went wrong, and believe me, you and I have both been on those conversations.
Josh: Yup, yup.
Rick: It's simply a phenomenal system. Obviously, we're not on video here but if you saw my gray in my beard, that showed my age on how many years I spend in the data center with some issues and things of this sort. This truly eliminates probably about 99% of your headaches.
Josh: Well, I'll tell you as this was developed, some of the concepts are very simple, but you scratch the surface. You think, hey, I just want to plug it in, and I think that's a lot of end users' mentality. They have so many things to worry about past layer one. Even the political, you know, environment that they're dealing with now and hurry up, hurry up, hurry up. It's very busy, so having a true plug and play solution, you know, I go to that term, I mean that's been used so much. It's cliché at this point.
Rick: But it's funny how you bring that up by saying, you know, you just want to plug it in. You just want to plug it in. That's how simple it is. You just want to plug it in and want it to work, and everybody's been saying that for two decades now, but it's never really been that way. It's like, well it's plug and play, but-
Rick: Plug and play, but, you know? I like this solution having our team worked on this, but you just try and make it as simpler for the user as possible. There's inherent issues with anything. You just want to make it as simple as possible. Take all the guesswork out of it. That combats with, you touched on the point today, you know, some proprietary type of things because ultimately manufacturers want you to buy their product, so that's always been the frustration we've seen from the users.
Yeah, it's great. It looks great. It's marketed very well, but man, once you get into it, once you invest in an initial solution and it looks great, now down the road, oh, now I got to pay out. I got to pay out, I got to pay out, I got to buy new stuff, I got to buy new stuff.
Josh: Buy new stuff, and then again, not to mention downtime.
Josh: Nobody wants that. Nobody.
