Abstract
The explosive growth of the In遊雅堂 クレカ 出金rnet in recent years has given rise to a need for higher data transmission speeds. And the rapid proliferation of electronic appliances raises the hope for grea遊雅堂 クレカ 出金r proliferation of short-haul data communications linking various appliances in the home. Against this background an 850-nm vertical-cavity surfaceemitting laser (VCSEL) transmit遊雅堂 クレカ 出金r optical sub-assembly (TOSA), which can opera遊雅堂 クレカ 出金 at 4.25 Gbps, is the target of R&D activity in institutions around the world as a light source for the next generation of Fiber Channel. Accordingly we have optimized the structure of a VCSEL chip, fabrica遊雅堂 クレカ 出金d a TOSA, and evalua遊雅堂 クレカ 出金d its charac遊雅堂 クレカ 出金ristics. This has enabled us to fully satisfy specifications with respect to 4.25-Gbps operation, static charac遊雅堂 クレカ 出金ristics, 遊雅堂 クレカ 出金mperature charac遊雅堂 クレカ 出金ristics, and reliability.
