Kawasaki, JapanNEC Compound Semiconductor Devices, Ltd. and NEC Electronics today introduced the NR3312 and NR4210 series of receiver optical sub-assembly (ROSA) modules used in Gbit/s optical transceivers. The NR3312 series is capable of operating across temperatures of -5 to +100 degrees Celsius, which NEC reports is the highest heat tolerance for 10Gbit/s optical modules in the industry.
The NR3312 series of cost-efficient PIN-type ROSAs features typical sensitivity
of -20dBm, typical responsivity of 0.9A/W, with minimum overload of
+1.5dBm. The PIN detector's and transimpedance amplifier's applied voltage is +3.3 VDC volts.
The NR4210 series of highly sensitive APD-type ROSAs features efficient conversion of optical signals to electronic signals, and is optimized for high-speed performance. The series achieves best-in-class sensitivity ratings of -28 dBm. Typical responsivity is 0.9A/W, with minimum overload of -7dBm
The NR3312 and NR4210 series support 10Gbps XENPAK, XPAK, and X2 transceivers with SC interfaces, as well as XFP transceivers with LC interfaces. Both series also support flexible printed circuit boards.
The NR3312 series is priced at US$260each in production quantities; the NR4210 series is priced at US$650each in production quantities. Samples are available now; mass production to begin August 2005. Click here for NR3312 and NR4210 specifications.
