GigOptix samples pre-production single-channel 40G and 100G SMT 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 for fiber-optic communications systems, has made available samples of its pre-production GX6255, a surface-mounted 8Vpp Mach–Zehnder Modulator (MZM) single-ended driver designed for use in 40G RZ-DQPSK and 100G DP-QPSK transponders.

The GX6255 is a low-power, compact surface-mount technology (SMT) MZM driver capable of outputting 8Vpp at up to 32Gb/s. It is designed to be fully compliant with industry-standard single-ended driven 40G RZ-DQPSK and 100G DP-QPSK modulators. It is typically used to amplify the data signals between the transponder multiplexer and its optical MZM and dissipates about 1.6W of power at 7.5Vpp output.

“Increasing consumer demand for bandwidth and the advent of cloud computing are driving network operators to upgrade from 10Gb/s links to larger 40Gb/s and 100Gb/s links to keep pace,” says VP of marketing Padraig O’Mathuna. “Building on the success of our recently announced GX62455 quad-channel driver, we are proud to extend our 40G and 100G driver offering with our newest single-channel 8Vpp driver to offer customers a complete driver portfolio solution for all their 40G and 100G driver requirements,” he adds. “Our driver portfolio, in combination with our comprehensive receiver portfolio of dual-channel transimpedance amplifiers (TIA) for 40G and 100G coherent systems and receiver amplifiers for 40Gb/s RZ-DQPSK systems, enable GigOptix to offer customers the widest selection of 40G and 100G solutions in the market,” he claims.

In a recent report on 100G components, market research firm Ovum forecasted that the 100G dense wavelength division multiplexing (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.
