Compact OC-192 Optical Transponder

This tiny optic fiber transponder will operate at transmission speeds of up to 10GB/s. It will be available in the third quarter of 2000.

Infineon Technologies North America Corp. recently announced its V23827-T18-C530 OC192 transponder, an OC-192 transponder for SDH/SONET environments. The company claims that at 3" X 1.6" X 0.6" (75 mm X 42 mm X 15 mm), the transponder is the industry's smallest. It can provide a link to local and regional data networks that at four times the speed of standard OC-48 solutions.

According to the company, the Infineon transponder links high-end routers to metropolitan networks at transmission speeds of 10Gb/s over a distance of up to 10km. Electrical parallel data (data and clock) of 16:1 LVDS (Low Voltage-Differential Signal) is transmitted at a data rate 622Mb/s over 16 channels. The module has a low power consumption of only six watts, and a directly modulated DFB (Distributed Feed Back) laser does not require internal cooling.

Also, the Infineon transponder converts the 16-bit wide electrical input coming from the framer chip into a 10Gb/s serial optical data stream. And 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 OIF (Optical Internetworking Forum).

"We are happy to offer OC-192/STM-64 networking capacity directly to emerging carriers and local Internet Service Providers (ISP)," says Jens Fiedler, program manager for fiber optics at Infineon. "This transponder is key to applying fiber optics solutions that will break down the 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."

Availability
The transponder will be available for sampling in Q3 of 2000.
