- Evolution, Challenges and Enabling Technologies for Future WDM-Based Optical Access Networks
- Upgrading current-generation Time Division Multiplexing TDM-based optical access networks will be a challenge in the future when end-user demand outgrows current network capacity. Wavelength Division Multiplexing WDM has been considered as an ideal solution to extend the capacity of optical networks without drastically changing the fiber infrastructure. This paper investigates...

- Switching and Traffic Grooming in WDM Networks
- This paper considers the role of switching in minimizing the number of electronic ports (e.g., SONET ADMs) in an optical network that carries sub-wavelength traffic. Providing nodes with the ability to switch traffic between wavelengths, such as through the use of SONET cross-connects, can reduce the required number of electronic...

- 120 Mbps upstream? Even 30 Mbps? Come on- who really needs it?
- Note: I've amended this post with corrective information, including this from our networking guru, George Ou. George,an actual engineer, points out: You cannot claim DOCSIS 3.0 is 160/120 down/up service and compare it to 50/30 down/up FiOS service. That is grossly misleading. 160/120 down/up in...

- Worst-Case Analysis of Dynamic Wavelength Allocation in Optical Networks
- This white paper considers Wavelength Division Multiplexed WDM optical networks. WDM networks use multiple communication channels over a single optical fiber. The channels are at different wavelengths. These networks support lightpaths, which are end-to-end circuit-switched communication connections that traverse one or more links and use one WDM channel per link.

- An Algorithm for Traffic Grooming in WDM Optical Mesh Networks With Multiple Objectives
- This paper studies a traffic grooming in Wavelength-Division Multiplexing WDM mesh networks for the SONET/SDH streams requested between node pairs. The traffic could be groomed at the access node before converting to an optical signal carried in the All-Optical network. The paper designs a virtual topology with a given physical...
