More power from laser modules for WDM systems
Oki Electric has developed a trio of high-power 1480nm pump laser diode modules for WDM (wavelength division multiplexing) optical transmission.
"We conducted the experiment based on locations such as marine vessels and mountain areas, where normal transmission routes including fixed LAN, wireless LAN, FOMA and PHS are unavailable or, at best, difficult to maintain", said Yasukazu Hontama, President of Broadband Media Company at Oki Electric.
"With the successful result which confirmed that the RS-M can transmit real-time video using a satellite phone connection, we believe the transmitter can be used in various applications, such as video transmission at disaster sites".
The RS-M, launched in February 2005, is a video compression transmitter that can easily send real-time live video from remote locations by simply connecting to a camcorder.
It integrates various functions necessary to transmit video, making possible an IP network based video transmitter with a compact sise of 180 x 117 x 105mm and weight of 1.2 kg.
The system can compress a video image to the MPEG-4 standard, with a maximum bandwidth of 1Mbit/s, transmitting real-time high definition video via various networks including fixed LAN, wireless LAN, FOMA and PHS.
Through each experiment, video transmission was accomplished with a delay of 3s or less, which was equivalent to video transmission via a FOMA line on ground.
The experiments were conducted with the help of Teikoku Sen-I, a company handling disaster prevention products.
Teikoku Sen-I provided the satellite phone system, Inmarsat M4, used in the experiments.
