Abstract

The aim of this project is to develop a new piece of equipment for optical communication called Optical Service Channel or FWL210-CSO, which will transmit low capacity voice and data over optical fibers. This entails the first service channel designed and developed in Brazil acting in the optical domain on the international market. It should replace, with superior performance, the others existing on the market, which function entirely in the electrical domain. This project aims to cater for companies that have optical fiber networks, among which the operators of public switched telephone networks, broadband access providers and public utility companies. FWL210-CSO should enable long distance voice and data communication over optical fiber without the need for intermediary layers of communications equipment. To effect the low capacity communication envisaged by this project, these layers make the investment unnecessarily expensive. FWL210-CSO will also enable integration with the customer’s PABX telephone and connection to the public switched telephone network, allowing access to external connections from any node on the network. In this way, engineers and technicians in the field will be able to communicate amongst themselves, from telecommunications stations, with the company’s offices using fixed phones and external cell phones and make conference calls. The equipment will operate as open channel, in the same way as the electric service channels in which all the nodes on the network will have simultaneous access to conversation (multiple access). The Optical Service Channel will also offer restricted channels, so that the signal will be regenerated in the node without, nevertheless, allowing local access. (AU)
