Given the tight power margins in Fiber to the Home (FTTH) network, one should carefully select fibers to overcome the macro-bending and staple losses which dominate especially at the consumer premises (CP). Bend-insensitive fibers (G.657 series) should be used in FTTH networks which gives network design architects more flexibility in system design, solves scalability issues in FTTH networks, and provides...
The purpose of this article is to review the key emerging innovations in laser and photonics systems as well as their design and integration, focusing on challenges and opportunities for solutions of societal challenges. Developments, their significance, and frontier challenges are explained in advanced manufacturing, biomedicine and healthcare, and communication. Systems, networks, and integration...
Most of the studies on traffic grooming focus on minimizing network link capacity and providing serving-relationship between client services and link capacity. Subsequent to this step, it is important to plan for adding/dropping client services over client service ports and setting up end-to-end lightpaths over network ports, which is however seldom investigated. We call such effort node hardware...
We present an automatic hardware module planning approach for optical transport networks. An optimal switch backplane size is identified that can achieve the most cost-effective hardware module planning.
ROADM elements in DWDM optical networks exhibit variations in pass-band amplitude response due to manufacturing variations and supplier diversity. We present a novel statistical approach for ROADM cascade penalty allocation, which reduces OSNR penalty with negligible impact to the worst case penalty estimate.
We present a cross-layer traffic grooming algorithm that balances layer-one and layer-zero signal regeneration capability to achieve the lowest network design cost. The cross-layer approach shows good cost reduction compared to the traditional non-cross-layer approach.
