ADVA Optical promotes low latency networks with new Raman amplifiers

NOVEMBER 4, 2010 -- ADVA Optical Networking (FSE:ADV) has introduced new latency-optimized Raman amplifier technology to its flagship FSP 3000 platform.

The main advantage of Raman amplification is its ability to provide amplification without the need to add supplementary fiber to the network, therefore allowing a shorter overall fiber path and faster transmission, ADVA Optical Networking asserts.

The new amplifier implements counter and co-propagating Raman amplification techniques. Traditional network implementations utilize higher-latency EDFAs to boost an optical signal before it is sent. They also use counter-propagation Raman techniques to boost the received optical signal.

ADVA Optical Networking says its new Raman technology has overcome gain and power-control barriers to eliminate the use of EDFA amplification. This method of allowing amplification within the transmission fiber itself significantly reduces the quantity of amplifiers that need to be deployed throughout the overall network, the company adds, which also minimizes the number of intermediate sites required along a route.

“In our trials, we have seen the new ultra low-latency Raman amplifiers reduce equipment latency by as much as 50 percent on key financial links,” said Brian Quigley, director of low-latency sales and strategy at ADVA Optical Networking. “This announcement is an example of ADVA Optical Networking’s continued commitment to drive latency from high-performance networks.”
