They were also shown to be targeted at different markets, 1G/10G with 100G and 10G/25G/100G. ns -----Original Message----- From: NANOG [mailto:nanog-bounces@nanog.org] On Behalf Of Aaron Gould Sent: Wednesday, February 14, 2018 10:58 AM To: 'Lewis,Mitchell T.'; 'Jerry Jones' Cc: 'NANOG' Subject: RE: 1/2u 100g Metro-E Aggregation Switch I just heard from a Juniper sales person about the ACX5448 (code name ACX5k+ or ACX+ or something like that) and about (4) 100 gig ports... also, about another ACX5k variant that may have 25 gig (25 gig is something the linux server engineer I work with has been talking about in his next datacenter server refresh).... Anybody else know anything about ACX5448 (ACX+) ? -Aaron
