Re: Rack rails on network equipment

We don’t care. We rack up switches maybe once or twice a year. It’s just not worth the effort to streamline. If we were installing dozens of switches a month, maybe. But personally I think it’s crazy to make rackability your primary reason for choosing a switch vendor. Do you base your

Well, I see IPv6 as double failure really. First, IPv6 itself is too different from IPv4. What Internet wanted is IPv4+ (aka IPv4 with bigger address space, likely 64bit). Of course we could not extend IPv4, so having new protocol is fine. It should just fix problem (do we have other problems I am

Andrey, hi. The speed rails are nice, and are effective in optimizing the time it takes to rack equipment. It's pretty much par for the course on servers today (thank goodness!), and not so much on network equipment. I suppose the reasons being what others have mentioned - longevity of service

Re: 100GbE beyond 40km

If you can’t wait for Juniper to release their supported QSFP28 100G-ZR optic, shop for third party 100G-ZR optics. I know many networks are already using third party QSFP28 100G-ZR optics in Juniper routers. I have one 80 km span between two MX204 routers using third party 100G-ZR optics

Does this have to be Ethernet? You could look into line gear with coherent optics. IIRC, they have built-in chromatic dispersion compensation, and depending on the card, would include amplification. On Fri, Sep 24, 2021 at 1:40 PM Randy Carpenter wrote: > > How is everyone accomplishing 100GbE

Look into EDFA amplifier systems. They work over a range of bands and are pretty affordable. They can carry regular 1310nm as well as C-Band. Although if you are carrying C-band you may have to compensate for chromatic dispersion. Happy to help, I love this stuff! On Fri, Sep 24, 2021 at 4:39
