Oki Electric has announced the development of the KGL4166, a 10Gbit/s Mach-Zehnder modulator driver IC for high-speed optical communication. This IC comes in the world's smallest package for a device equipped with bias-T. It also features an output voltage of 9V peak-peak, which is a 1.5x increase from conventional chips, achieving the largest output voltage in the industry.
For 10Gbit/s optical communication, achieving long distance data transmission and reducing the cost of dispersion compensation are keys.
Although new methods such as duo binary module and differential phase shift keying (DPSK) that are strong in relation to dispersion are being developed, they require driver ICs with higher output amplitude as the modulator is driven with higher voltage than conventional ones.
The KGL4166 is a 10Gbit/s optical modulator driver IC that runs on 9V peak-peak output voltage.
By adopting high voltage process elements and optimising circuit designs, the driver IC achieves output voltage of 9V peak-peak, putting it in the industry's highest-class while maintaining the high quality wave characteristics for which Oki driver ICs are noted.
In addition, by miniaturising the chip, Oki achieves the world's smallest mounting area of 10.9 x 8mm, for a chip equipped with bias-T.
'We believe the KGL4166 will have an impact on the 10Gbit/s optical communication market, which is expected to grow', said Masayuki Tsuboi, President of Optical Components Company at Oki Electric.
'This super-small driver IC will enable customers in the optical transceiver business to create smaller, higher quality optical communication devices'.
'Oki will launch this product from the fiscal year ending March 2008 and utilising the advantages of high-speed and high voltage in the device, we will target a 50% share in the Mach-Zehnder modulator driver IC market'.
