GigOptix expands 100G portfolio and samples quad 7.5V DWDM driver

GigOptix Inc of Palo Alto, CA, USA, which designs modulator and laser drivers and transimpedance amplifier (TIA) ICs based on III-V materials as well as polymer electro-optic modulators, has announced the availability for sampling of its new GX62455, a quad-channel 7.5Vpp Mach–Zehnder Modulator (MZM) driver designed for 100G DP-QPSK (dual-polarization quadrature phase-shift keying) long-haul optical transmitters. 

The GX62455 is a high-voltage-output 32Gb/s quad MZM driver in a compact form-factor (25mm x 32mm) GPPO module that includes integrated low- and high-frequency chokes and requires no external components for fast and easy application, the firm says. The connectors have been designed to be form-factor compatible with industry-leading 100G multiplexer and modulators for easier system integration.

Key features include: data rates up to 32Gb/s per lane for 100G DP-QPSK applications; low RMS jitter; adjustable single-ended Vout to 7.5Vpp; adjustable eye cross point; a wide range of input voltage levels; and typical power consumption of 6W at Vout=7.5Vpp.

“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 7.5V while maintaining industry-leading power consumption within the market's smallest footprint,” says vice president Padraig O’Mathuna. “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,” he adds. GigOptix is providing a complete physical-layer solution to enable customers to achieve what is claimed to be not only optimal system performance with the smallest size but also the lowest power with the most cost-competitive solution on the market.

In a recent report on 100G components, market research firm Ovum forecasted that the 100G DWDM line-side market would launch in 2010 and grow at a compound annual growth rate (CAGR) of 140% to more than 16,000 units by 2015.
