FIRST FIBER OPTIC TRANSPACIFIC VIDEO TESTS CARRIED VIA THE NORTH PACIFIC CABLE, PACIFIC TELECOM CABLE SAYS

 VANCOUVER, Wash., Jan. 7 /PRNewswire/ -- Pacific Telecom Cable Inc. (PTC) has announced that Tokyo Broadcasting System (TBS) has successfully completed a series of tests to demonstrate the feasibility of transmitting international high-quality television signals via fiber optics using the 1,260 Mbit/s North Pacific Cable (NPC).
 Tests were conducted between Miura, Japan, and Pacific City, Ore., in cooperation with International Digital Communications Inc. (IDC) of Japan and PTC using a Toshiba CODEC and optical interface equipment developed by TBS and Toshiba. HDTV tests at 140 Mbit/s were conducted Dec. 8 and NTSC tests at 45 Mbit/s were conducted on Dec. 17.
 On Dec. 24, an additional test fed a 45 Mbit/s signal to the Portland Gateway Operations Center of PTC. This center provides connectivity to U.S. domestic fiber optic networks.
 PTC will participate in additional tests during 1993 that will connect to inland U.S. transmission systems. Advantages of terrestrial fiber transmission include high bandwidth, high reliability and less delay. PTC noted that TBS expects to use fiber in place of its current Ku-band services between the U.S. and Japan to provide high-quality pictures and voice, and to avoid time delay during live programming.
 "This pioneering effort helps usher in what futurists such as George Gilder call the fibersphere," said Stephen Lovas, president of PTC. "Gilder along with MIT Media Lab's Professor Nicholas Negroponte and others see fiber optics taking on a greater role in moving bandwidth- demanding services such as HDTV, CAD/CAM and telemedicine, thereby releasing radiofrequency spectrum to support wireless services including cellular, mobile telephony and the mobile office."
 NPC is the highest-capacity cable in the Pacific and the first to provide a direct connection between the United States and Japan. It was constructed as a joint project between PTC, IDC and Cable & Wireless plc of the United Kingdom.
