Broadcom Corporation, a global innovation leader in semiconductor solutions for wired and wireless communications, today introduced the BCM88650 series, the world's highest density 100 gigabit Ethernet (GbE) switching solution, enabling the design of switching platforms with densities up to 4,000 100 GbE ports. With the industry's highest level of integration, the BCM88650 system on chip (SoC) combines the features and functionality of a complete line card into a single chip. Together with Broadcom's leading FE1600 (BCM88750) fabric, the BCM88650 SoC enables a new generation of high density networking solutions exceeding 100 terabits per second (Tbps). See the technology in action at INTEROP 2012 or visit http://go.broadcom.com/interop12 to learn more.

Odd. I thought Ethernet topped out at 40 Gb/s before other more exotic networking protocols had to be used. Guess they broke through that barrier, which IMO can only be good news. :)

I consider Infiniband exotic. :)

I believe, as far as physical media is concerned, the current "limit" (used very loosely) is roughly 25.78Gbps on Single Mode Fiber (or 25Gbps at the MAC). What they do in 40G/100G Ethernet is they use multiple fiber links (either 4 full duplex links or 10) and the Ethernet frames are transmitted in a cascaded/parallel structure. The physical layer reconstructs the parallel data into serial data which is then passed up to the higher OSI layers. It is "essentially" a modified version of 10GBASE-R which adds in some restrictions to 64b/66b and adds "Alignment Markers" to handle de-skewing the parallel links so that the data is received/processed in a coherent manner.

With 100GbE, you can either use 4 full duplex links using high quality optics and single mode fiber, or 10 full duplex links using cheaper quality optics and multimode fiber, or you can also go electrical and use a big ass cable with a total of 40 conductors not including signal grounds and shielding (10 differential transmitters + 10 differential receivers).

wow, I was at microsoft job shadowing for the new job im hoping to get and job shadowed a Network Engineer there and they had 10GBe and all that. 100GbE would be nuts!
