ML9XX41
World’s highest power optical intensity and 80 km transmission combined
1  2  NEXT 
Outline
We have commercialized an optical modulator integrated laser diode, ML9XX41, for 10 gigabit (Gbps) per second transmission as the light source for miniature transmitters in a next generation high-speed optical communication system which combines the world’s highest power optical intensity and 80 km transmission. It is suitable for installation on standardized miniature optical transceivers such as XENPAK and XFP to build a low cost 80 km transmission system that does not require an optical amplifier.
Features
With the existing optical modulator integrated laser diode, there was a problem of the optical modulator output light frequency fluctuation increasing as the optical output increased, making the distance transmitted with low error rate shorter. With this product, we have achieved 80 km transmission with a low error rate even under the condition of high power light intensity by controlling the frequency fluctuation with the optimal design of the optical modulator.
Applications
10 Gbps Miniature Transceivers (XENPAK, XFP)
10 Gbps Optical Transmitter Module
Main Specifications
Chip edge output: 10 mW (modulator bias voltage = 0V)
  Dispersion resistance 1600ps/nm (equivalent to 80 km of normal dispersion fiber)
  10Gbps optical quenching ratio: (more than 10.5dB)
  Modulating voltage amplitude: 2.0Vpp
Future Deployment
We plan to expand the operation temperature range effective to lower the power consumption of optical transceivers.
