MUNICH -- Infineon Technologies AG today said it has developed an OC-192 transponder for Sonet/SDH environments that measures just 3 x 1.6 x 0.6 inches, making it the smallest 10-gigabits-per-second solution on the market, according to the company.
The V23827-T18-C530 transponder links high-end routers to metropolitan networks at transmission speeds of 10 Gbits/s over a distance of up to 10 kilometers. Electrical parallel data (data and clock) of 16:1 LVDS (low voltage-differential signal) is transmitted at a data rate 622 megabits/s over 16 channels. The module will have low power consumption of only 6 watts.
Infineon said it was able to shrink the device because it use a directly modulated distributed feedback (DFB) laser, which does not require internal cooling.
Jens Fiedler, program manager for fiber optics at Infineon North America Corp. in San Jose, said,"This transponder is key to applying fiber optics solutions that will break downthe barriers that slow down the Internet and other data transport. By using our smallest OC-192 solution, system providers can offer a high-port density that will enable terabit data transmission."
The Infineon transponder converts the 16-bit-wide electrical input coming from the framer chip into a 10 Gbit/s serial optical data stream. The receiver section converts the serial optical data stream back into the 16 LVDS-compliant channels. The device incorporates high-frequency PLL for clock generation and recovery and meets the specification for OC-192 SR data transmission proposed by the Optical Internetworking Forum.
The transponder will be available for sampling in the third quarter of 2000.
