New Pump Module
SDL Announces New Generation of 980 nm Pump Modules
Pump Module Powers Up to 300 mW to Satisfy Market Demand for Higher Bandwidth, Higher Channel Count and Greater Distances
SAN JOSE, March 1 /PRNewswire/ -- SDL, Inc. (Nasdaq: SDLI - news) announced today a new generation of pump modules for use in erbium doped fiber amplifiers (EDFAs). These new high power pump modules will be used in dense wavelength division multiplexed (DWDM) fiber optic networks to satisfy the projected increase in demand for higher channel count and longer transmission distance.
The SDLO-2700 Series utilizes SDL's new 6540 chip that has operated at over 500 mW of optical power, and an advanced fiber coupled package with reduced dimensions that has greatly improved thermal performance. The combination of new chip technology and new packaging techniques allows the introduction of module power levels to 300 mW. The SDLO-2700 series is designed to meet the performance and reliability requirements of the rapidly growing EDFA market for long haul terrestrial DWDM networks as well as Metro/CATV networks.
The SDLO-2700 uses a new generation of chip specifically designed to operate with SDL's patented fiber Bragg grating. This unique combination has pushed the maximum power available from grating stabilized 980 nm pump modules to a new high of 300 mW.
Previously, SDL's highest power grating stabilized pump modules operated at 180 mW. The use of fiber Bragg gratings with pump lasers creates wavelength stabilized pumps that result in more stable EDFA performance, independent of input signal wavelength. As one of the first manufacturers of 980 nm pump lasers, SDL has leveraged its unique vertically integrated laser diode capability and its considerable design and volume production experience to meet new market demands.
SDLO-2700 Series modules are available now in sample quantities. Production quantities are expected in the second half of 2000.
According to Gregory P. Dougherty, chief operating officer of SDL, ``We believe the 2700-Series product line will enable new EDFA designs that will help to satisfy market demand for higher bandwidth, higher channel count and greater distances. This pump module uses SDL's 6540 chip which, we believe, represents the most capable 980 nm pump chip in the world. This chip, coupled with our new planar package, allows us to break through the 180mW barrier to new highs for 980 nm pump modules. Because of the improved thermal performance, reduced package height and ultra high power at a cost effective price, we believe we will be
positioned to penetrate markets in which SDL has not previously participated.'
