OVERVIEW |
In regard to the next-generation network society—in which broadcasting and communications will converge—HD video-distribution systems running broadcasting on the communications infrastructure are being anticipated. Accordingly, optical access networks supporting large-capacity data transmission including video services will become an ever more critical infrastructure from now onwards. Playing a key role in such optical access networks, the GPON system "AMN1220" can provide gigabit-class services to homes and offices in a "triple-play" format including voice, video, and data. Moreover, being capable of responding to rapid increases in data traffic on metro-access networks, the 40-Gbit/s extender system "AMN6300" and the CWDM/DWDM system "AMN6200" are available. Hitachi Group is expanding such photonic network systems—which can flexibly respond to the demands of next-generation networks supporting new kinds of services—and proposing "optical transport solutions" that take advantage of its collective manufacturing strength.
