Fujitsu has developed new optical amplifier technology with the potential to quadruple the number of splits and double the transmission distance for PON optical access systems.
Fujitsu and Fujitsu Laboratories have developed a burst-mode optical amplifier technology with a semiconductor optical amplifier (SOA), an integrated SOA-array module fabrication technology, and an SOA chip fabrication technology enabling uncooled operation. The company said these innovations enable its new 10 Gbps optical amplifier to support 128 connections and maximum distance of 40 km from the central office. This compares with the current split ration of 1:32 and top reach of 20 km.
In addition, the optical amplifier supports symmetric 10 Gbps service.
