“…Broadband optical access services based on fiber to the premises (FTTP) architectures are now commercially available [1][2][3][4][5][6]. The invention of the Internet, its massive growth, and the vast applications it offers has not only increased the number of users, but also increased the individual bandwidth demand for voice, data, and video-on-demand, which are now offered by both telephone companies and cable television (CATV) service providers [7].…”

Applications of non-blocking large-scale optical switches based on three-dimensional micro-electro-mechanical system (3D-MEMS) technology with small size and low power consumption are described for fiber-based broadband access networks. The low-loss and fast-switching 3D-MEMS switches offer remotely reconfigurable and automated operational solutions for access networks such as fiber management, preventative maintenance, monitoring, testing, and troubleshooting of a large number of end customers. Furthermore, the wavelength, data rate, and protocol-transparent nature of 3D-MEMS switches results in a future-proof optical distribution network design for future higher speed and higher capacity wavelength division multiplexing overlay upgrades over the passive optical network (PON). We show that large-scale 3D-MEMS switches deployed in PON environments can offer over an order of magnitude in capital and operational savings in comparison to manual patch panels (in deployed fiber hardware, real estate, and manual labor) with minimal impact on the overall network design.

“…S INCE the demand for broadband services is increasing rapidly, the last mile data access network must provide high data rate in a more economic way. Time division multiplexed passive optical network (TDM-PON) and wavelength division multiplexed PON (WDM-PON) have been widely developed for the access networks [1], [2]. Meanwhile WDM-PON technologies can also provide symmetric bandwidth connections at very high data rates, in the 1-10 Gbps range per end-user [3].…”

We propose and demonstrate a novel and simple signal remodulation ring-based wavelength division multiplexed passive optical network (WDM-PON) scheme with the capability to mitigate the Rayleigh backscattering (RB) beat noise in colorless signal remodulation operation. The effects of RB can be avoided since the backscattering effects and upstream signals travel in opposite directions. Here, 10 Gb/s DPSK downstream is used to launch into reflective optical semiconductor amplifier (RSOA)-based optical network unit (ONU) for signal remodulation at 1.25 or 2.5 Gb/s on-off keying (OOK). Moreover, the network performance has also been analyzed and discussed.

“…It is concluded that PONs have played a primary role in contributing to the increasing popularity of broadband services, i.e., ultra-broadband services on the Internet. Many articles on the overview, strategic deployment, and standardization of PONs have been published [4]- [6]. Especially, the Full Services Access Network (FSAN) group [7] has clarified PON technical feasibility, accelerated standardization including interoperability and implementation, and promoted trials.…”
