GigOptix, Inc. (NYSE MKT: GIG) says it is delivering engineering samples of its GX62472, a surface-mounted technology (SMT) Mach Zehnder modulator (MZM) quad linear driver designed with integrated GPPO outputs for 400-Gbps DWDM metro and long-haul optical transmitters.
The company says it designed the driver in cooperation with its Tier 1 customers to address 400-Gbps quadrature amplitude modulation (QAM) requirements. GigOptix lists the following as key features of the GX62472:
- Data rates up to 32 Gbaud for use in 400-Gbps QAM applications
- Coplanar differential inputs compatible with industry surface-mounted DSPs
- GPPO-connectorized outputs compatible with commercially available 100-Gbps DP-QPSK MZMs
- Low RMS jitter degradation
- “Excellent” linearity
- Single-ended output up to 6 Vpp
- Integrated temperature sensor and bias -T networks
- Available gain control and peak detector.
“We are very excited to announce the successful engineering introduction of our first 400G MZM driver, the GX62472,” commented Andrea Betti-Berutto, Senior Vice President and Chief Technology Officer of GigOptix. “The solution integrates GigOptix’s high-performance linear MMIC designs in a compact form factor suitable for use in both line cards and transponders. The GX62472 integrates an SMT-to-GPPO transition in the package that simplifies customers’ designs, shrinking the system size and saving costs by reducing the labor required to manufacture the system. Moreover, the coplanar differential inputs ensure excellent high-speed electrical signal integrity between the DSP and the driver, while the single ended GPPO connector ensures optimal coupling of the amplified electrical signals with the optical modulator.”
