An ATM PON system overlaid with a 155-Mb/s optical star network for customer networking and fiber to the premises
TLDR
In this article, a light-emitting diode-based optical star network, wavelength-compatible with the asynchronous transfer mode (ATM) PON system, showed a power penalty of 1.1 dB compared to back-to-back connection.Abstract:
We propose a method to implement a 155-Mb/s optical star network using existing passive optical network (PON) cable plant and demonstrate its feasibility experimentally. The light-emitting diode- (LED) based optical star network, wavelength-compatible with the asynchronous transfer mode (ATM) PON system, showed a power penalty of 1.1 dB compared to back-to-back connection. The overlay network had little effect on ATM PON signals.read more

Novel schemes for local area network emulation in passive optical networks with RF subcarrier multiplexed customer traffic
Abstract: This paper proposes two novel optical layer schemes for intercommunication between customers in a passive optical network (PON). The proposed schemes use radio frequency (RF) subcarrier multiplexed transmission for intercommunication between customers in conjunction with upstream access to the central office (CO) at baseband. One scheme employs a narrowband fiber Bragg grating (FBG) placed close to the star coupler in the feeder fiber of the PON, while the other uses an additional short-length distribution fiber from the star coupler to each customer unit for the redirection of customer traffic. In both schemes, only one optical transmitter is required at each optical network unit (ONU) for the transmission of customer traffic and upstream access traffic. Moreover, downstream bandwidth is not consumed by customer traffic unlike in previously reported techniques. The authors experimentally verify the feasibility of both schemes with 1.25 Gb/s upstream baseband transmission to the CO and 155 Mb/s customer data transmission on the RF carrier. The experimental results obtained from both schemes are compared, and the power budgets are calculated to analyze the scalability of each scheme. Further, the proposed schemes were discussed in terms of upgradability of the transmission bit rates for the upstream access traffic, bandwidth requirements at the customer premises, dispersion tolerance, and stability issues for the practical implementations of the network.

TL;DR: In this article, a bidirectional wavelength division multiplexed passive optical net-work (WDMWN) architecture is proposed and experimentally demonstrated, which fully utilizes the superior optical properties of an incoherent continuous-wave (CW) supercontinuum (SC) source, based on a unique wavelength band allocation scheme of the C-band for an optical line terminal (OLT), the Lband for optical network units (ONUs), and the Uband for channel monitoring.
