GigOptix samples quad 7.5-Vpp DWDM driver for 100G

AUGUST 24, 2010 -- GigOptix, Inc. has announced the availability for sampling of its new GX62455, a quad channel 7.5-Vpp Mach-Zehnder modulator (MZM) driver designed for 100G dual-polarization quadrature phase-shift keying (DP-QPSK) long-haul optical transmitters.

AUGUST 24, 2010 -- GigOptix, Inc. (OTCBB:GGOX) has announced the availability for sampling of its new GX62455, a quad channel 7.5-Vpp Mach-Zehnder modulator (MZM) driver designed for 100G dual-polarization quadrature phase-shift keying (DP-QPSK) long-haul optical transmitters.

GigOptix says its GX62455 is a high voltage output, 32-Gbps quad MZM driver in a 25x32-mm GPPO module that includes integrated low and high frequency chokes and requires no external components for fast and easy application. The connectors on the GX62455 have been designed to be form factor compatible with what the company described as “industry-leading” 100G multiplexer and modulators for easier system integration.

Key features of the GX62455 that GigOptix cited include:

  • Data rate up to 32-Gbps per lane for 100G DP-QPSK applications
  • Low RMS jitter
  • Adjustable single ended Vout to 7.5 Vpp
  • Adjustable eye cross point
  • Wide range of Input Voltage levels
  • Typical power consumption: 6 W @ Vout = 7.5V pp


“We are ramping production of our first-generation 100G driver and have now extended our offering with the GX62455 to support the higher output voltage of 7.5 V while maintaining industry-leading power consumption within the market’s smallest footprint," stated Padraig O’Mathuna, vice president of GigOptix. ”This MZM driver in conjunction with our current 100G GX3222 transimpedance amplifier (TIA) offers customers a one-stop-shop for 100G DP-QPSK applications and we intend to further develop system ‘bundles’ consisting of a driver and a TIA with future modulators that are tailored for specific DWDM applications.”
