GigaWaM—Next-Generation WDM-PON Enabling Gigabit Per-User Data Bandwidth

Next generation optical network and its optical components

“…Telecommunications providers are faced with the dual challenge of reducing operating costs while increasing the bandwidth available to end users [7]. They will be required to: 1) provide the network with great flexibility, 2) simplify the network management and operations and 3) increase the level of automation so as to reduce operational expenditures (OPEX).…”

“…The application of PON has moved on to interactive broadband networks ever since. Applications have evolved from basic passive optical networks (PON) to broadband passive optical networks (BPON) and Ethernet passive optical networks (EPON), and now gigabit passive optical networks (GPON), all based on Time Division Multiplexing Access (TDMA) [1][2][3][4][5][6][7][8]. Network providers are facing the challenge of developing new business models through innovation of their existing network infrastructure.…”

Bidirectional 40Gb/s/λ, 100km-reach, channel-reuse WDM-PON employing tunable optical transceiver with optical intensity detection-based wavelength management

“…The wavelength-division-multiplexing passive optical network (WDM-PON) has been regarded as a promising solution for next-generation optical access networks requiring high security, easy maintenance, great flexibility, and broad bandwidth [1][2][3][4]. Driven by ever-increasing user demands for broad-band services to support high-quality internet protocol television (IPTV), e-learning, interactive games, and future looking peer-to-peer multimedia services, it is expected that the data-rate demand will continuously grow, and that numerous access nodes will be deployed over the next few decades.…”

Gigabit Access Passive Optical Network Using Wavelength Division Multiplexing—GigaWaM

“…The "Gigabit access PON using wavelength division multiplexing (WDM)" (GigaWaM) was initiated in June 2008. The key technical objectives of the GigaWaM project were to implement 64 WDM channels at 50 GHz channel spacing, delivering 1 Gb/s symmetric data transmission to each user, over a distance of 20 km on a single fiber [5]. L and C bands of the optical spectrum are used for downstream and upstream channels.…”
