OTN processors from the core to the network edge

The latest silicon design announcements from PMC and AppliedMicro reflect the ongoing network evolution of the Optical Transport Network (OTN) protocol.


"There is a clear march from carriers, led in particular by China, to adopt OTN in the metro"

Scott Wakelin, PMC

OFC/NFOEC 2012 industry reflections - Part 1

The recent OFC/NFOEC show, held in Los Angeles, had a strong vendor presence. Gazettabyte spoke with Infinera's Dave Welch, chief strategy officer and executive vice president, about his impressions of the show, capacity challenges facing the industry, and the importance of the company's photonic integrated circuit technology in light of recent competitor announcements.

ECI Telecom's Apollo mission

The privately-owned system vendor has launched Apollo, a family of what it calls optimised multi-layer transport platforms. 

 

Event

ECI Telecom has launched a family of platforms that combines optical transmission, Ethernet and optical transport network (OTN) switching and IP routing.

The 9600 series platforms, dubbed Apollo, combines the functionality of what until now has required a packet-optical transport system (P-OTS) and a carrier Ethernet switch router (CESR).

ECI refers to the capabilities of such a combined platform as optimised multi-layer transport (OMLT). Analysts view the platform as a natural evolution of P-OTS rather than a new category of system.

High fives: 5 Terabit OTN switching and 500 Gig super-channels.

Infinera has announced a core network platform that combines Optical Transport Network (OTN) switching with dense wavelength division multiplexing (DWDM) transport. "We are looking at a system that integrates two layers of the network," says Mike Capuano, vice president of corporate marketing at Infinera. 

 

"This is 100Tbps of non-blocking switching, all functioning as one system. You just can't do that with merchant silicon."

Mike Capuano, Infinera
