Oki Semiconductor pump laser modules extend range of fiberoptic systems

Sept. 6, 2001
Oki Semiconductor (Sunnyvale, CA) has released two new high-power 1480-nm pump laser diode modules for the next generation of erbium-doped fiber amplifiers (EDFAs). By deploying the new modules throughout their long-haul DWDM-based fiberoptic networks, customers can increase the distance between each EDFA.

Oki Semiconductor (Sunnyvale, CA) has released two new high-power 1480-nm pump laser diode modules for the next generation of erbium-doped fiber amplifiers (EDFAs). By deploying the new modules throughout their long-haul DWDM-based fiberoptic networks, customers can increase the distance between each EDFA, thereby lowering the number of EDFAs needed to regenerate a signal. Both new modules support the high-performance needs of DWDM for EDFAs.

Designed specifically for long-haul fiberoptic systems, the OL4128N-160 and OL4128N-180 modules are lower in cost than their predecessors, while still providing EDFA manufacturers with improved performance. The modules incorporate a Thermo-Electric Cooler design allowing for lower current operation and improved temperature stability. The OL4128N-160 and OL4128N-180 can operate at 160 mW and 180 mW of kink-free power, respectively. In addition, the modules have an industry-standard 14-pin butterfly package design, making them compatible with other pins.

Samples of the OL4128N-160 and OL4128N-180 are available now. In volumes of 1000 units, the OL4128N-160 modules are priced at $1100; the OL4128N-180 modules at $1500. For more information, visit www.okisemi.com .
