- Enables a High-Definition, High Quality Video Service for Movie
Distribution and Telemedicine -
OKI
Electric Industry (TOKYO:6703) today announced it has succeeded in
developing the world’s first 160Gbps ultra high-speed optical next
generation access (NGA) asymmetric PON system using hybrid Optical Time
Division Multiplexing (OTDM) and Optical Code Division Multiplexing
(OCDM)(1). 160Gbps is equivalent to sending 6 channels of uncompressed
ultra high-definition video or 33 channels of high-definition video per
second. Transmitting signals at a speed of 160Gbps on a single optical
fiber downstream means super high-resolution and high quality video
delivery service that requires data of over 1GB, such as movie
distribution and telemedicine, can be offered.
The research that led to OKI’s achievement was conducted as part of the
"Research and development for ultra high-speed optical NGA Asymmetric
PON system,” under the auspices of NICT’s(2)
“Basic Technology Promotion System for Private Sectors Program.”
The mainstream optical access systems used by carriers today are GE-PON
system (1.25Gbps) in Japan and G-PON system in US and Europe (2.5Gbps),
which are used mainly to transmit data and video. In such optical access
systems, the communication capacity per user when 16 users are
connected, is limited to 78 to 156Mbps.
The ultra high-speed NGA Asymmetric PON system developed by OKI
significantly increases the communication capacity compared to
conventional optical access systems. The system achieves 128-times
larger capacity than that of GE-PON systems and 64-times larger capacity
than G-PON systems. This means that with 16 users, telecom carriers can
offer a 10Gbps communication capacity for each user, enabling
high-resolution and high quality video delivery service.
“We are excited to announce the development of the world’s first
high-speed NGA Asymmetric PON system. With this system, OKI will
contribute a valuable tool to industries that need to transmit
high-quality videos, such as the movie and telemedicine industries, and
plan to help rejuvenate the communication environment in local areas,”
said Takeshi Kamijoh, General Manager of Corporate R&D Center at OKI.
“With the market needs in mind, we will continue to make efforts to
develop smaller and more stable equipment and continually improve the
quality for optical access system over 100Gbps.”
Optical Line Terminal (OLT) is the main equipment for this system.
