Optical access network management using reflection optical memory

Scalable Optical Access Network Design using Variable Optical Splitters

With the increase in the number and bandwidth of services that must be offered by an access network, and the unpredictability of the range of services that users might demand in future, it is essential that long term solutions are investigated for designing scalable and dynamic optical access networks. This paper provides an adaptive and scalable design for the access network architecture based...

Scalable Active Optical Access Network Using Variable High-Speed PLZT Optical Switch/Splitter

This paper proposes a scalable active optical access network using high-speed Plumbum Lanthanum Zirconate Titanate (PLZT) optical switch/splitter. The Active Optical Network, called ActiON, using PLZT switching technology has been presented to increase the number of subscribers and the maximum transmission distance, compared to the Passive Optical Network (PON). ActiON supports the multicast sl...

Technologies for Next Generation Optical Access Network

Introduction of the GE-PON system has accelerated the use of FTTH in Japan, changing the access network from simply an Internet connection to a social infrastructure that provides services directly related to daily life, such as IP telephone service. Mitsubishi Electric has the largest share of the GE-PON market in Japan and is now working on the next generation GE-PON. The role of the NGN is b...

High speed OFDM-CDMA optical access network.

We demonstrate the feasibility of a 16 × 3.75 Gb/s (60 Gb/s aggregate) Orthogonal frequency division multiplexing-code division multiple access passive optical network for next-generation access applications. 3.75 Gb/s PON channel transmission over 25 km single-mode fiber shows 0.1 dB dispersion and 0.9 dB crosstalk penalties. Advantages of the system include high capacity, enhanced spectral ef...
