Remote transfer of high-resolution video information finds more applications in detached display applications for large
facilities such as theaters, sports complex, airports, and security facilities. Active optical cables (AOCs) provide a
promising approach for enhancing both the transmittable resolution and distance that standard copper-based cables
cannot reach. In addition to the standard digital formats such as HDMI, the high-resolution, long-distance transfer of
VGA format signals is important for applications where high-resolution analog video ports should be also supported,
such as military/defense applications and high-resolution video camera links. In this presentation we present the
development of a compressionless, high-resolution (up to WUXGA, 1920x1200), long-distance (up to 2 km) VGA
extenders based on serialized technique. We employed asynchronous serial transmission and clock regeneration
techniques, which enables lower cost implementation of VGA extenders by removing the necessity for clock
transmission and large memory at the receiver. Two 3.125-Gbps transceivers are used in parallel to meet the required
maximum video data rate of 6.25 Gbps. As the data are transmitted asynchronously, 24-bit pixel clock time stamp is
employed to regenerate video pixel clock accurately at the receiver side. In parallel to the video information, stereo audio
and RS-232 control signals are transmitted as well.
We introduce the most recent progress in the optimization of ultrafast fiber lasers for building ultralow timing jitter
signal sources. Using a sub-20-attosecond-resolution timing jitter measurement technique, we optimize the timing jitter
of optical pulse trains from mode-locked Er-fiber and Yb-fiber lasers to 70 attoseconds and 175 attoseconds,
respectively, when integrated from 10 kHz to 40 MHz offset frequency. To our knowledge, these results correspond to
the lowest rms timing jitter demonstrated from fiber lasers so far, the equivalent phase noise of which is comparable to
that of the best microwave sources available, with much reduced cost and engineering complexity.
