For the first time, the feasibility of large port count nanosecond reconfiguration time optical switches is demonstrated using a novel hybrid approach, where Mach-Zehnder interferometric (MZI) switches provide low loss high speed routing with short semiconductor optical amplifiers (SOAs) being integrated to enhance extinction. By repeatedly passing signals through a monolithic hybrid dilated 2...

Sangjin Jeong et al. 97 Optical Border Gateway Protocol (OBGP) is an extension to BGP for Optical Cross Connects (OXCs) to automatically setup multiple direct optical lightpaths between many different autonomous domains. With OBGP, the routing component of a network may be distributed to the edge of the network while the packet classification and forwarding is done in the core. However, it is n...

An ultra-dense optical interconnection network is proposed for massively parallel processors. Using twodimensional arrays of beam-steering vertical cavity surface-emitting lasers (VCSEL) as space-division switching elements, a single-chip, free-space photonic banyan network (or other multi-stage networks) can be constructed. Our scheme does not require critical optical alignment and can be easi...

We present a novel bidirectional WDM-based optical access network featuring reconfigurable capacity assignment. The architecture relies on the PolMUX technique allowing a compact, flexible, and bandwidth-efficient router in addition to source-free ONUs and color-less ONUs for cost/complexity minimization. Moreover, the centralized architecture contemplates remote management and control of polar...

This draft presents a summary of issues related to transmission of IP packets over optical networks. This is a compilation of many drafts presented so far in IETF. The goal is to create a common document, which by including all the views and proposals will serve as a better reference point for further discussion. The novelty of this draft is that we try to cover all the main areas of integratio...

background:  wi-fi allows electronic devices such as laptops to exchange data or connect to a network resource. the main goal of this study was to assess the bioeffects of short term exposure to 2.4 ghz microwave radiation emitted from a common wi-fi router on sperm quality. materials and methods: male wistar rats were divided into 7 groups; i, sham exposed 4 h/day for 7days at 30 cm from the r...

Perkembangan teknologi jaringan dari waktu ke semakin pesat, oleh karena itu diperlukan akses yang aman atau secure. Dengan banyaknya jaringan, maka akan banyak pula peluang terjadinya kejahatan di dalam tersebut. Penelitian ini menggunakan metode penetration testing bertujuan untuk menganalisis celah keamanan pada login router Mikrotik SMKN 2 Sumbawa. Dalam melakukan trial attack, penelitian B...
