Avanex expands 10G tunable transponder portfolio with optical duo-binary modulation

Optical communications component and module maker Avanex Corp of Fremont, CA, USA has expanded its 10G extended-reach tunable transponder product portfolio with the new PowerReach 10Gb/s Optical Duobinary (ODB) transponder, which is on display at this week’s 33rd European Conference and Exhibition on Optical Communication Conference (ECOC 2007) in Berlin, Germany (17–19 September). The PowerReach ODB is available for sample testing with selected customers, and is expected to be released in full production in December.

The new device combines Avanex’s lithium niobate modulators with its tunable transponder design to create a high-performance extended-reach tunable transponder with reach of up to 160km without added amplification.

The PowerReach ODB’s modulation technology provides higher dispersion tolerance and narrower laser line-width – two key features that allow optical signals to travel longer distance with low transmission bit error. The transponder can typically achieve a bit error rate below 10-3 with optical signal-to-noise ratio (OSNR) as low as 12dB through ±3200 ps/nm, while maintaining power consumption below 12W (7W at 35oC). The module also compliant with large form-factor 300-pin MSA standards.

The PowerReach ODB’s features allow equipment makers to provide highly reliable, cost-effective extended-reach transmission network solutions, Avanex claims.
