Summary of the technology
A new Passive-Optical-Network (PON) for Fiber-To-The-Home (FTTH) services has been developed in the frame of the National Research Project TEYDE. While current FTTH networks as GPON and EPON can reach a maximum of 32-64 users, the proposed PON can serve more than 4000 users, thanks to a new device for distributing the signal among the users that intelligently recycles the noise generated by other elements of the network. Partners to further develop the device and/or to establish license agreements with technical cooperation are sought.
Access to internet is limited for many people to slow speed or a high cost. A fiber arriving to each home is proving nowadays 100Mbps in USA and Japan by GPON (Gigabit PON) and/or EPON (Ethernet PON) FTTH networks at the same prize of 6Mbps ADSL services in Europe. While ADSL provides service to one user per cooper pair cables and GPON and EPON serve to 32-64 users, this new promising technology can provide access to more than 4000 users per PON network.
Successful current FTTH-PON networks as GPON and EPON distribute the signal among the users by splitting it. For example, if providing signal to 64 users, only about 1% of the signal power can be distributed to each home.
This technology regenerates this 1% to a 99% level, at a new design of the common passive power splitter used in GPON and EPON, by recycling the noise generated by the transmitter device of the user terminals. So that maintaining a Passive network, the PON network can be extended up to 1000 users (4000 users by FEC techniques).
