    Thats the new service line. Don't know the exact devices so I'll just take your word for it ? But as for the old service Linus is talking about 2 min in the video. That's just a passive CWDM MUX/DEMUX right? So there should be multiple 1Gbps links on separate wavelengths, no? Not a "10Gbps wavelenght that is split out into ten 1Gbps connections", right?

    Sure, PON is a bit different, but it also uses WDM, so it would be relateble to the topic. But with CWDM, you should just have a MUX/DEMUX on both sides with colored 1Gbps trancievers. So you don't have a single 10Gbps wavelength, but ten wavelengths used for 1Gbps. Also its a bit weird calling it a 10Gbps wavelengh since it's just spectrum and depends on what a tranceiver is capable of. You can fire both 1Gbps and 10Gbps on the 1310 or 1550 nm.

    "It takes this 10G wavelength and splits it into ten 1G wavelengths"... Nooooo, this is not how CWDM (or WDM in general) works. I think Linus needs to do a techquickie on WDM and as an example PONs. Maybe he'll polish up his networking along the way Also, don't think that you will be able to acquire a IPv4 /24 prefix, since they are pricey AF, but you should easily get a /48 or a /32 IPv6 range, register an ASN and peer directly in IPv6 via VAN-IX.

    I was wondering if someone actually owns one of those soundbars. I read it includes it's own chromecast. But can you cast only audio on it? I have a media server on my NAS. And now I just watch content directly from it via smart TV apps. But my TV doesn't have eARC (only standard ARC) and as I understand it's not enough to actually carry the DTS X/Atmos content to the soundbar. So can I cast the whole video/audio via the soundbar chromecast?

    This kinda doesn't make sense. In that case their ISP is getting the 10Gbps connection with VAN-IX. And they have to share that with that ISPs other traffic. And it will basically depend on the ISPs routing policies.

    Figures that it's some sort of L1/L2 transport service. But to get connectivity with all the VAN-IX peers - you need to setup BGP. For that you need your own ASN and public IP range.
  7. PsychoXLR
    How else will they get access to VAN-IX?
  8. PsychoXLR
    Maybe I'm a bit old school but I really really doubt that a "software" router can hold a candle to a hardware solution, even a few generations older one. Does LTT actually has a ASN? Will they be as a full peering partner on Van-IX?

    Hey, just wanted to note that GPON and DWDM are very different things. GPON does use some basic WDM to combine upstream and downstream (and some times a third for CATV) wavelengths, but that is not even close to DWDM levels. GPON (same for XGPON) are about the method of using a single fiber uplink and a series of passive optical splitters to connect multiple optical terminals. As for the 10G PON - there also symetric 10G PON standarts, there is not sinble one standard, but a bunch and different HW venfors are betting on different ones.
