GigOptix starts shipping volume production orders of 40G RZ-DQPSK receiver amplifiers to tier 1 telecom OEM

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, says that its GX3240 high-performance 40G RZ-DQPSK (return-to-zero differential quadrature phase shift keying) receiver amplifier has entered mass production and is shipping in volume to a tier 1 telecom OEM.

Made available as samples last November, the GX3240 is a high-gain, broad-bandwidth and low-power differential amplifier in a compact 3mm x 3mm QFN form-factor package that is capable of directly driving a 40G de-multiplexer. GigOptix says that the product was developed through close collaboration with a tier 1 telecom OEM, consistent with GigOptix's strategy of partnering with industry-leading customers to define and drive commercialization.

“The GX3240 concept is a very challenging design and significantly strengthens GigOptix’s existing 40G receiver amplifier portfolio,” says chief technology officer Andrea Betti-Berutto. “Paralleling our previously announced 40G DPSK receiver amplifier and 100G DP-QPSK driver developments, we aligned this product's development with a tier 1 customer’s requirements... This enabled us to design the right device for the market,” he adds.

In its most recent report on 40G components, market research firm Ovum forecasted that the 40G RZ-DQPSK market would rise at a compound annual growth rate (CAGR) of 41% from 10,000 units in 2010 to more than 56,500 units in 2015. Two GX3240’s are used in each 40G RZ-DQPSK transponder.
