ADVA runs the rule over its TeraFlex platform

Gazettabyte talks to Jörg-Peter Elbers about the recent trial of ADVA’s FSP 3000 TeraFlex platform in Tele2’s network and gets his views on industry trends.

It is early morning and the air is cool. I'm seated outside at a coffee bar in Herzliya’s marina awaiting Jörg-Peter Elbers, senior vice president, advanced technology, who is in Israel visiting local ADVA staff.   

He arrives as the bar opens and we are the only customers.

Just as we are about to start, the waitress informs us that the barista has yet to arrive. Breakfast can be ordered but we must wait for coffee.

ADVA adds quantum-resistant security to its optical systems  

ADVA has demonstrated two encryption techniques for optical data transmission to counter the threat posed by quantum computing.  

“Quantum computers are very powerful tools to solve specific classes of mathematical problems,” says Jörg-Peter Elbers, senior vice president, advanced technology at ADVA. “One of these classes of problems is solving equations behind certain cryptographic schemes.”

Public-key encryption makes use of discrete logarithms, an example of a one-way function. Such functions use mathematical operations that for a conventional computer are easy to calculate in one direction but are too challenging to invert. Solving such complex mathematical problems, however, is exactly what quantum computers excel at. 

A fully-fledged quantum computer does not yet exist but the rapid progress being made in the basic technologies suggests it is only a matter of time. Once such computers exist, public key based security will be undermined. 

The looming advent of quantum computers already threatens data that must remain secure for years to come. There are agencies that specialise in tapping fibre, says Elbers, while the cost of storage is such that storing huge amounts of data traffic in a data centre is affordable. “The threat scenario is certainly a real one,” says Elbers.

Meeting the many needs of data centre interconnect

High capacity. Density. Power efficiency. Client-side optical interface choices. Coherent transmission. Direct detection. Open line system. Just some of the requirements vendors must offer to compete in the data centre interconnect market.

“A key lesson learned from all our interactions over the years is that there is no one-size-fits-all solution,” says Jörg-Peter Elbers, senior vice president of advanced technology, standards and IPR at ADVA Optical Networking. “What is important is that you have a portfolio to give customers what they need.”

OpenFlow extends its control to the optical layer

OpenFlow may be causing an industry stir as system vendors such as ADVA Optical Networking extend the protocol's reach to the optical layer, but analysts warn that it will take years before the technology benefits operators' revenues.


"We see OpenFlow as an additional solution to tackle the problem of network control"

100 Gigabit for the metro

ADVA Optical Networking has launched a 100 Gigabit transmission card designed for metro wavelength-division multiplexing (WDM) applications.

The firm claims this is an industry first: a direct-detection-based 100 Gigabit-per-second (Gbps) design using four, 28Gbps channels rather than current 10x10Gbps schemes.


"Data centre operators want to make best use of the fibre insfrastructure and get lower overall cost, footprint and power consumption"
