Wavelength-agile optical access networking system
SPIE Proceedings, 2011In this paper, we introduce our Home2015 project - wavelength-agile optical access networking system. We propose a multi-wavelength access network to offer higher system capacities for next-generation optical access. Our proposed concept of virtual PON (VPON) is introduced to realize dynamic ONU re-grouping functionality.

Optical access network technologies for future radio access networks
2017 IEEE Photonics Society Summer Topical Meeting Series (SUM), 2017This paper describes optical access network technologies that support future radio access networks. Packet-based BBU is expected to accommodate multiple services and PON with low-latency scheme is a promising candidate to for MFH transmission in future radio access networks.

Coherent Optical Access Networks
2018The constant increase in IP traffic, mainly driven by the growth of the number of connected users and the demand for bandwidth per user, has profoundly influenced the evolution of optical communication systems as a whole, including fiber-based access networks, which constitute the last mile of an optical system, directly connecting the edge IP network ...

Active optical access networks
Communications Engineer, 2003While fast connections over copper are possible, higher bandwidth requirements can only be met with fibre connections in the local loop. This paper reviews the structure and operation of active optical access networks in providing telecom services to the user.

DPSK for optical access networks
2012 IEEE Colombian Communications Conference (COLCOM), 2012The development of technologies for optical access networks and user demand for more bandwidth has enabled consider increasing rates and improve the current coverage of access networks. Currently there are various ways to achieve this goal, one relates to the use of modulations in the signal processing in both the OLT and the ONU.

IEEE Network, 1996
Both broadcast CATV and switched telephony access networks have evolved, over decades, to deliver their respective services efficiently. But these networks are not necessarily optimal for services that are rapidly emerging. This suggests that the access infrastructure will likely change in the future, driven by demands for new services and the costs of

Hybrid Optical Wireless Access Networks
2013 5th International Conference on Computational Intelligence and Communication Networks, 2013This paper describes a dynamic reconfiguration algorithm for a hybrid fiber wireless network, which takes advantage of dynamic reconfiguration in WDM based optical networks to provide bandwidth on the fly. The WDM technique for optical networks allows network operators to extend the existing capacity of passive optical networks manifolds.
