Does anyone make a coherent CWDM 40G QSFP? I thought so, but the first couple places I checked, I struck out at. This would be for a passive mux\MROADM. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP
Not aware of ACO/DCO in QSFP form factor. Inphi is doing 100G QSFP28 PAM4 DWDM for MS. Probably the best you will see for a while. On Tue, Oct 18, 2016 at 4:50 PM Mike Hammett <nanog@ics-il.net> wrote:

Apparently I just remembered the big transport platforms using coherent 40G and 100G and assumed there was a cheap variant, but there isn't. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Tim Durack" <tdurack@gmail.com> To: "Mike Hammett" <nanog@ics-il.net>, "nanog list" <nanog@nanog.org> Sent: Tuesday, October 18, 2016 9:28:02 PM Subject: Re: Coherent CWDM 40G QSFP Not aware of ACO/DCO in QSFP form factor.

True 40 gigs is rare period. Most of the time it is bandwidth limiting on a 100 gig wave. ________________________________ From: NANOG <nanog-bounces@nanog.org> on behalf of Mike Hammett <nanog@ics-il.net> Sent: Wednesday, October 19, 2016 11:46 PM To: Tim Durack Cc: nanog list Subject: Re: Coherent CWDM 40G QSFP Apparently I just remembered the big transport platforms using coherent 40G and 100G and assumed there was a cheap variant, but there isn't. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Tim Durack" <tdurack@gmail.com> To: "Mike Hammett" <nanog@ics-il.net>, "nanog list" <nanog@nanog.org> Sent: Tuesday, October 18, 2016 9:28:02 PM Subject: Re: Coherent CWDM 40G QSFP Not aware of ACO/DCO in QSFP form factor.
