Avanex Extends PowerReach(TM) Tunable Transponder Product Line Into the L-Band



FREMONT, Calif., March 14 / -- Avanex Corporation (NASDAQ:AVNX) a pioneer of intelligent photonic solutions that enable next-generation optical networks, today announced a full L-band version of its PowerReach(TM) tunable transponder. This new product extends the flexibility of dynamically tunable transmitters across the entire DWDM band. The PowerReach(TM) transponder also offers excellent optical-signal-to-noise-ratio (OSNR) performance.

The PowerReach(TM) transponder provides wavelength tunability from 1570 nm to 1607 nm with a +/-25pm accuracy and features a chromatic dispersion window of 2000 ps/nm, well beyond the industry standard of 1600 ps/nm specified in ITU-T G691, ITU-T G.709, Telcordia GR253 and OIF SFI4-01.0. The increased dispersion performance permits much longer reach signal transmissions.

The PowerReach(TM) tunable transponder has a power output from +1 to + 6dBm, accepts multi-bit rate from 9.995 to 11.3Gb/s and it offers the flexibility of zero or selectable chirp LiNbO3 modulators and multiple L-band tunable laser options. This latest product enhancement enables rapid adoption by customers, as it only requires a small incremental qualification effort beyond the work already completed for the current C-band module.

"As communication networks require greater bandwidth, our customers are increasingly looking for solutions in the L-band," said Dr. Giovanni Barbarossa, chief technology officer of Avanex. "Dynamically tunable modules are also a requirement for the latest generations of transmission equipment. The improved PowerReach(TM) Full L-Band tunable transponder is a perfect choice for this market segment and is an example of Avanex's commitment to develop differentiated products that leverage our key strengths in optical components, optical integration and control techniques."

The PowerReach(TM) Full L-Band tunable transponder serves metro, long-haul and ultra-long-haul DWDM applications up to 3,000 kilometers, offers up to 80 channels at 50 GHz spacing, and allows remote optical, electrical and alarm management and control functions through the I2C(TM) bus interfaces.
