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. |
