In this paper, a study on a fully passive WDM/PON ring architecture which reaches 19 km distance, while serving more than 1000 users with symmetric several hundred Mbit/s per user is presented. The design is based on SARDANA (Scalable Advanced Ring -based Passive Dense Access Network Architecture) and was generated as an alternative solution, with its novelty laying on the use of L-band in line remote amplification. The simulation of an extended access WDM/TDM PON formed in a double fibre ring with single fiber trees was created. The network's operation has been tested for several conditions of usage (i.e. maximum number of users, transmission power and pump power) and an optimization of the design has been performed. The target was to achieve, with given transmission and pump power, the reach of more then 1000 users with input power high enough to permit the use of an RSOA at the ONU. The use of L-band signals and special doped fiber has permitted the effective use of RSOAs in the total of the end users.

“…electronic switches and routers, can be reduced. Extended reach (ER) access network has been proposed to achieve this [1][2][3]. The ER access network makes use of a high capacity, high split-ratio passive optical network (PON), with a reach of more than 100 km, to combine optical access and metro into a single system [3].…”

The local exchange [between the head-end office and the customer optical networking units (ONUs)] would contain a small amount of compact, low power physical layer elements, such as optical amplifiers and temperature controlled arrayed waveguide gratings for wavelength multiplexing and demultiplexing.…”

“…Each wavelength channel carries 10 Gbit/s data over a 100 km reach and connects up to 512 optical network units (ONUs). EDFAs are used to overcome the path loss [1,2]. In this Letter, we focus on burst-mode experiments based on time-domain multiple access (TDMA) on a single wavelength channel.…”
