NFOEC, Baltimore, July 9, 2001—JDS Uniphase Corporation (Nasdaq: JDSU and TSE: JDU) today announced its 300 mW, 14XX nm pump module for Raman applications. The JDS Uniphase SDLO-3400 Series provides the highest power and highest efficiency currently available for Raman pumping.
Fiberoptic systems are being designed for higher channel counts, higher transmission speeds, and longer transmission distances, all of which result in the need for more optical power. Ultra-long haul systems benefit from the excellent gain flatness and low noise of the Raman Pump Units (RPUs), which are used to complement conventional EDFA power sources. In addition to Raman-enhanced EDFAs, the JDS Uniphase 3400 Series Raman 14XX pump laser can be used both for distributed Raman pumping in ultra-long haul 40 Gb/s systems requiring very high power and simply as a lower-cost, higher-efficiency substitution for two lower-power pumps.
The 3400 Series 14XX laser is based on a high-power indium phosphide (InP) semiconductor laser chip housed in a 14-pin butterfly package. It provides output powers from 180 to 300 mW with grating stabilized wavelengths selectable from 1420 to 1495 nm. Both the chip and the integral thermo-electric cooler are more efficient than competing products, with the result that 300 mW of optical power output draws a maximum of only 14 W input, including the power requirements of the chip and cooler (calculated at 20-year end of life conditions).
