GigOptix ramps GX6261 40G driver shipments

JULY 27, 2010 -- GigOptix Inc. (OTCBB: GGOX) says that its GX6261, a 40G driver for differential quadrature phase-shift keying (DQPSK) systems, has entered mass production and is now shipping in volume with GigOptix’ previously announced portfolio of GX3240 and GX3220 DQPSK receiver amplifiers to Tier 1 telecom customers.

JULY 27, 2010 -- GigOptix Inc. (OTCBB: GGOX) says that its GX6261, a 40G driver for differential quadrature phase-shift keying (DQPSK) systems, has entered mass production and is now shipping in volume with GigOptix’ previously announced portfolio of GX3240 and GX3220 DQPSK receiver amplifiers to Tier 1 telecom customers.

According to Padraig O’Mathuna, GigOptix’s vice president of marketing, "The GX6261 ramp to production confirms industry analysts’ predictions of strong demands for high-speed 40G and 100G systems. 40G DQPSK is now one of the fastest growing segments in the optical communications space. It is being deployed within metropolitan networks to economically address the bandwidth bottlenecks caused by the exponential growth in enterprise and consumer traffic generated by increased usage of Smartphones and IPTV.

“We developed the GX6261 in close cooperation with our Tier 1 customer to address their DQPSK application and we are now their platform’s sole driver solution,” O’Mathuna added.

The GX6261 is a high voltage differential driver for 40G DQSPK Mach-Zehnder modulators used in long-haul and metro optical transponders. Features of the GX6261 that GigOptix calls out include:

  • “excellent” electrical eye performance
  • small footprint -- it’s 6x6 mm2 surface mounted device with in-package integrated high frequency coils
  • power dissipation that GigOptix says is typically 1 W lower compared to comparable competiting devices -- a total savings of 2 W per transponder since two drivers are used in each DQPSK transponder.


Daryl Inniss, vice president and practice leader at Ovum, commented "40G DWDM is one of the fastest-growing segments in optical communications. We expect to see the demand continue to expand as operators transition from 10G to 40G to address the increased demand by consumers and enterprises for more bandwidth. We especially see major DQPSK technology deployments happening in Asia."

In its most recent report on 40G components, Ovum forecasted that the 40G DWDM market for DQPSK drivers would grow from $14 million in 2010 to over $34 million in 2015 with a CAGR of 44%
