ECI Telecom demos 100 Gigabit over 4,600km

• 4,600km optical transmission over submarine cable
• The Tera Santa Consortium, chaired by ECI, will show a 400 Gigabit/ 1 Terabit transceiver prototype in the summer
• 100 Gigabit direct-detection module on hold as the company eyes new technology developments

"When we started the project it was not clear whether the market would go for 400 Gig or 1 Terabit. Now it seems that the market will start with 400 Gig."

Jimmy Mizrahi, ECI Telecom

Cisco Systems' intelligent light

Network optimisation continues to exercise operators and content service providers as their requirements evolve with the growth of services such as cloud computing. Cisco Systems' announced elastic core architecture aims to tackle  networking efficiency and address particular service provider requirements.

“The core [network] needs to be more robust, agile and programmable”

AppliedMicro samples 100Gbps CMOS multiplexer

AppliedMicro has announced the first CMOS merchant multiplexer chip for 100Gbps coherent optical transmission. The S28032 device supports dual polarisation, quadrature phase-shift keying (DP-QPSK) and has a power consumption of 4W, half that of current multiplexer chip designs implemented in BiCMOS.

Dan Sadot on coherent's role in the metro and the data centre

Gazettabyte went to visit Professor Dan Sadot, academic, entrepreneur and founder of chip start-up MultiPhy, to discuss his involvement in start-ups, his research interests and why he believes coherent technology will not only play an important role in the metro but also the data centre.

"Moore's Law is probably the most dangerous enemy of optics"
