JANUARY 17, 2011 -- Ciena Corp. (NASDAQ: CIEN) says that Reliance Globalcom will deploy its coherent 40G optical networking technology on a cable route that connects the United Kingdom, Spain, Italy, and Egypt. Spanning more than 6,400 km, the upgraded cable route will add 2.4 Tbps of capacity to help transport traffic between the Atlantic crossing and Asia portions of Reliance Globalcom’s global submarine network.
The upgrade to 40G technology via Ciena’s ActivFlex 6500 Packet-Optical Platform with 40G ultra long haul interfaces is a part of a strategy to increase the submarine network capacity without disrupting existing customer traffic or adding cost and complexity to the network, Ciena adds. Ciena's 40/100G technology leverages dual-polarization phase shift key (DP-PSK) coherent optics, electronic dispersion compensation, and directionless and colorless ROADM functionality.
According to a source at Ciena, the ActivFlex 6500 Packet-Optical Platform will support both DP-QPSK and DP-BPSK. Reliance is known to be using the DP-BPSK option for the extended reach benefits.
“Even in uncertain economic times, delivering services to a global customer base of hundreds of service providers, thousands of enterprises, and millions of consumers requires an agile, high-capacity network,” said Rory Cole, president and COO, Carrier & ISP, of Reliance Globalcom. “By adding Ciena’s 40G technology at our terminal stations, we increase our capacity by a factor of four with a clear, in-service path to 100G without disrupting existing customers, re-engineering our network or sending ships out to lay more fiber. With this one simple step, we bolster the value and extend the lifespan of our submarine network.”
