GigOptix samples 28G modulator driver for 40G & 100G applications

GigOptix Inc of San Jose, CA, USA (which supplies semiconductor and optical components including modulator and laser drivers and transimpedance amplifier ICs based on III-V materials) has started sampling its 28Gb/s Mach-Zehnder modulator (MZM) driver, designed for 40G and 100G metro and long-haul optical transmitters.

Key features of the GX6262 include: a data rate up to 28Gb/s for use with 40G DQPSK and 100G DP-QPSK modulation formats; low RMS jitter degradation; differential output form 7Vpp; adjustable eye cross point; and low power consumption of 2.7W@Vout=7Vpp. 

“We developed the GX6262 in close collaboration with our tier 1 customers to be fully compliant with their specific requirements to ensure that their DQPSK transponders would be successful products,” says chief technology officer Andrea Betti-Berutto. “The competitor product burns more power than our GX6262, it requires more real estate on the print circuit board, and is not as cost effective as the GX6262 solution,” he claims. “Since each 40G DQPSK transponder requires two GX6262 drivers, these advantages are compounded and, therefore, the GX6262 enables customers to implement much more compact and efficient transponder solutions.”

Samples of the GX6262 are available for evaluation with an evaluation board.
