Hierarchical Optical Path Cross-Connect Node Architecture Using WSSIWBSS
نویسندگان
چکیده
propose a new HOXC node architecture that is composed of MEMS-based WSSf\NBSS. The architecture minimizes the number of mirrors, which leads to lower node cost and higher reliability. Quantitative evaluations of the number of mirrors needed for HOXC and single-layer OXC architectures are given; the restriction of add/drop optical path ratio is considered. We sho~ that the number. of mirrors can be halved from that of Single-layer OXC, which will lead to a substantial node cost reduction.

Compact Matrix-Switch-Based Hierarchical Optical Path Cross-Connect with Colorless Waveband Add/Drop Ratio Restriction
We propose a compact matrix-switch-based hierarchical optical cross-connect (HOXC) architecture that effectively handles the colorless waveband add/drop ratio restriction so as to realize switch scale reduction. In order to implement the colorless waveband add/drop function, we develop a wavelength MUX/DMUX that can be commonly used by different wavebands. We prove that the switch scale of the ...

متن کاملOptical Cross-Connect Switch Architectures for Hierarchical Optical Path Networks
This paper proposes new switch architectures for hierarchical optical path cross-connect (HOXC) systems. The architectures allow incremental expansion of system scale in terms of the number of input/output fiber ports, wavebands, and optical paths per waveband. These features assure the cost-effective introduction of HOXCs even at the outset when traffic volume is not so large. Furthermore the ...
متن کاملOptical cross – connect routing node demonstrator for DWDM wavelength path networks
We describe the design and performances of a strictly non-blocking optical cross-connect node demonstrator for WDM wavelength path networks. The optical cross-connect (OXC) prototype was experimentally tested as an 2 x 2 WDM system with two input / output ports and two wavelengths per port. The OXC was inserted in a 95 km network with a STM-16 bit stream per channel. The performance of a single...
متن کاملOptical Node Architectures That Utilize Dedicated Add/Drop Switches to Realize Colorless, Directionless and Contentionless Capability
This paper proposes optical node architectures for the single-layer optical cross-connect (OXC) and hierarchical OXC (HOXC) that utilize dedicated add/drop switches for originating/terminating traffic at a node. For both single-layer OXC and HOXC, three architectures with different restrictions on add/drop capabilities are presented. The performance of the proposed architectures is compared thr...
