Impact of network reliability on network costs in next generation access networks

Abstract: Today's access networks are still mainly based on copper cable infrastructure in the first mile. The geographic extension of conventional access service areas and with this also the structure of the access/aggregation network is mainly defined by the resistance of the copper lines - and thus the copper loop length - as well as by the switching capacity of the electro-mechanic telephone exchanges in the past. The evolution towards next generation optical access networks will provide a new degree of freedom in network design due to the higher reach of optical transmission. This will potentially lead to much larger service areas serving several thousands of customers from a single location. This increased concentration of customers will have a significant impact on network reliability and service availability in next generation access networks. In this paper we will review the impact of network reliability and availability on network costs in next generation optical access networks. The results show that show that there is a significant cost impact in all consolidation scenarios depending on the aspired failure penetration.

Optical networking in smarter data centers: 2015 and beyond

Abstract: Advantages of optical networking for highly virtualized data centers are discussed, including lower power, improved scalability and port density, and tighter I/O integration with processors. Use cases include enterprise infrastructure underlying software-defined networking, supercomputing, and multi-site backup applications.

Method apparatus network and system for establishing an optical communication link for wavelength division multiplexing transmission

Abstract: The present invention describes an optical line termination (OLT1, OLT2), an optical network unit (ONU1, .., ONU7), an optical network (1000) as well as a system and a method for establishing an optical communication link for wavelength division multiplexing transmission and providing a plug and play scheme. In particular an optical line termination (OLT1, OLT2) broadcasts on a dedicated communication channel preferably unidirectional using all available communication bandwidth, wavelength information about available communication channels/wavelengths as wavelength subsets to optical network units. Because all transmission channels are used, an optical network unit attempting to connect to the optical line termination receives the required information for establishing an optical communication link no matter to which frequency its transmitter/receiver is at present adjusted. After having received the broadcast information the optical network unit (ONU1,.., ONU7), adjusts its transmitter and/or receiver to a communication channel/communication wavelength that is indicated as being free and in return transmits its identification to the optical line termination which builds a list associating optical network units and the wavelength used for communication by the respective optical network units which is stored and transmitted in return in the next broadcast. In the context of the present invention power management schemes and calibration schemes are encompassed as well.

Next generation hybrid wireless-optical access with TWDM-PON

Abstract: This paper reviews the latest progress in ITU-T standards on high-speed access networks. We focus on the employment of the time and wavelength division multiplexed passive optical network (TWDM-PON) for the next generation wireline and wireless broadband services. Several applications with TWDM-PON are proposed. We investigate the proposal by developing a prototype system to test the physical layer capability and network service provisioning. Test results demonstrate salient features of employing TWDM-PON to provide broadband access for residential, business, wireless backhaul and fronthaul.
