"40Gbps has even less value in the metro than in the core"

Tuesday, November 8, 2011 at 10:53AM 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.

The Swedish system vendor has adopted coherent detection technology for 100 Gigabit-per-second (Gbps) optical transmission, unlike other recent metro announcements from ADVA Optical Networking and MultiPhy based on 100Gbps direct-detection.
"Metro is a little bit diverse. You see different requirements that you have to adapt to."
Thursday, September 15, 2011 at 8:43AM 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."

Thursday, April 21, 2011 at 11:42AM A project to develop optical networks using terabit light paths has been announced by a consortium of Israeli companies and universities. The Tera Santa Consortium will spend 3-5 years developing orthogonal frequency division multiplexing (OFDM)-based terabit optical networking equipment.
“This project is very challenging and very important”
Shai Stein, Tera Santa Consortium
Friday, March 11, 2011 at 11:53AM What has been announced?
Infinera has detailed Terabit coherent detection photonic integrated circuits (PICs). The pair - a transmitter and a receiver PIC – implement a ten-channel 100 Gigabit-per-second (Gbps) link using polarisation multiplexing quadrature phase-shift keying (PM-QPSK). The Infinera development work was describe in papers given at the OFC/NFOEC event held in Los Angeles.
Infinera recently demonstrated its 5x100Gbps PIC carrying traffic within Interoute Communications’ network. The 5x100Gbps PIC-based system will be available commercially in 2012.
“We think we can drive the system from where it is today – 8 Terabits-per-fibre - to around 25 Terabits-per-fibre”
Dave Welch, Infinera
Tuesday, November 9, 2010 at 9:35AM Fujitsu Labs has developed a compensation technique that tackles non-linear effects in a coherent receiver-based optical transmission system. The technique promises to boost the reach of 100 Gigabit-per-second (Gbps) and future higher speed systems.
“That is one of the virtues of the technology; it is not dependent on the modulation format or the bit rate”
Takeshi Hoshida, Fujitsu Labs
