Abstract

Recently, broadband services such as VoD (Video on Demand) are attracting much attention as a driving force for broadband FITL (fiber-in-the-loop) systems. Considering recent deployment of ultrahigh-count optical fiber cable, which generally consists of a number of 8-channel fiber ribbon, the star topology based on the fiber-rich concept is becoming attractive for realizing highly scalable FITL systems. However, it has a drawback in HDT-(host digital terminal) size volume, because it requires exclusively dedicated optical interfaces for each fiber. An optical-array transceiver is expected to solve the HDT size problem effectively. This paper reports the newly developed 8- channel array optical transceiver designed for star access networks, which features high sensitivity, large dynamic range, and high cross talk tolerance.
