Oki Electric Industry Co., Ltd. today announced it has developed a 10Gbps differential outputs type driver IC (KGL4186KD) for Mach-Zehnder (MZ) modulator for optical communication. The KGL4186KD achieves a power consumption of 0.9W (at the output swing of 6.4Vpp), one of the lowest of its kind, and is assembled in a small ceramic package that is advantageous for high frequency characteristics. Samples are available starting today.
“We are pleased to present our driver IC which has the lowest power consumption in its class. The size of 10Gbps transceivers for long distance optical communication are becoming smaller, as seen in 300pin SFF MSA. To solve the heating problem critical in such a small size module, demand for lower power consumption is increasing for all the electrical and optical components in transceiver modules, such as driver IC as well as modulators,” said Masayuki Tsuboi, President of Optical Components Company at Oki Electric Industry. “Leveraging its high-speed, high output device technology, OKI plans to gain market share in the 10Gbps optical communication market with the MZ driver IC series.”
The KGL4186KD is a MZ modulator driver IC with differential outputs operating under the positive supply voltage. Differential output amplitude varies from 3Vpp to over 6.4V. KGL4186KD, based on the well-established OKI GaAs PHEMT technology, offers a high-quality waveform. Also, by the design optimization for the output circuit, which is a key for the power consumption, OKI achieves the lowest class power consumption of 0.9W at differential output amplitude of 6.4V pp. In addition, the 4mm square ceramic package provides a small footprint as well as a high-quality waveform at high frequency.
KGL4186KD enables all the customers to take a dual drive type MZ modulator or single-ended (low voltage) drive type MZ modulator, which are based on LiNbO3 (Lithium niobate) or InP (indium phosphide), into their design for 10Gbps transceivers of a small form factor with high performance and low power consumption.
OKI will showcase its 10Gbps modulator driver IC for optical communication at its booth at the Optical Fiber Communication Conference & Exposition and the National Fiber Optic Engineers Conference (OFC/NFOEC2008) (Booth No. 2415).
