CWDM and OEO Transport Architectures
نویسنده
چکیده
This paper outlines the features and service benefits of integrated CWDM and OEO metro transport architectures. Following an overview of the xWDM product and network evolution and the ITU-T G.695 standard for CWDM architectures, examples of OEO transport platforms such as Multi-Service Provisioning Platforms (MSPPs) and Regenerative CWDM (R-CWDM) transport platforms are presented. The need for 10G services is discussed with reference to current and future OEO network implementations. Expansion of existing 2.5G R-CWDM platforms to accommodate future 10G xWDM OEO upgrades is foreshadowed using new, recently announced photonic and electronic technologies.

Effects of dietary oregano essential oil and vitamin E supplementation on meat quality, stress response and intestinal morphology in pigs following transport stress
This study investigates the effects of dietary oregano essential oil (OEO) and vitamin E (Vit E) supplementation on meat quality, stress response and intestinal morphology in pigs following transport stress. A total of 288 finishing pigs were randomly assigned to three groups: a basal diet or a basal diet supplemented either with 200 mg/kg Vit E or 25 mg/kg OEO. After a 28-day feeding trial, to...
متن کاملEffect of oregano essential oil supplementation on performance, biochemical, hematological parameters and intestinal histomorphometry of Japanese quail (Coturnix coturnix Japonica)
This study was performed to evaluate the efficacy of two levels of dietary oregano essential oil (OEO) on growth performances, biochemical, hematological parameters, and intestinal histomorphology in Japanese quail. A total number of 99 quail chicks were divided into three groups (33 quails per group): Control, OEO 150 mg kg-1, and OEO 300 mg kg-1 treated groups for 42 day...
متن کاملImpairment-aware Design & Routing for Transparent Optical Networks
Although all-optical transport may be the ideal, some OEO conversions will likely be necessary to control signal impairments. The placement of OEO conversions in optical networks affects critical design targets such as degree of transparency, cost, and robustness vis-à-vis demand forecast uncertainties. We explore two different impairment-aware OEO placement paradigms, Focused Design and Unifor...

In this article, we report the studies of various device architectures of organic lightemitting devices (OLEDs) incorporating highly efficient blue-emitting and ambipolar carriertransport ter(9,9-diarylfluorene)s, and their influences on device characteristics. The device structures investigated include single-layer devices and multilayer heterostructure devices employing the terfluorene as one...
متن کاملCharacterization of Active Packaging Films Made from Poly(Lactic Acid)/Poly(Trimethylene Carbonate) Incorporated with Oregano Essential Oil.
Antimicromial and antioxidant bioactive films based on poly(lactic acid)/poly(trimenthylene carbonate) films incorporated with different concentrations of oregano essential oil (OEO) were prepared by solvent casting. The antimicrobial, antioxidant, physical, thermal, microstructural, and mechanical properties of the resulting films were examined. Scanning electron microscopy analysis revealed t...
