Dengan berkembangnya teknologi komunikasi dan informasi melalui data tanpa kabel yang dimana keamanan jaringan wireless LAN menjadi penting perhatian, terhubung ke internet pada dasarnya tidak aman selalu dapat diekploitasi oleh para hacker cracker. Ketika berkomunikasi lalu lintas dikirim melewati terminal untuk mencapai tujuan, maka saat itu pengguna lain bertanggungjawab memiliki kesempatan ...

Telecommunication networks are experiencing a dramatic increase in demand for capacity, much of it related to the exponential takeup of the Internet and associated services. To support this demand economically, transport networks are evolving to provide a reconfigurable optical layer which, with optical cross-connects, will realize a high-bandwidth flexible core. As well as providing large capa...

We present a sub-millisecond dynamic optical path set up scheme for the multi-mode switching router. In particular, we have implemented the proposed integrated multi-mode scheduler in FPGA hardware in an optical switching testbed, and have demonstrated application triggered real-time sub-millisecond optical path setup. Another key contribution is that the proposed approach brings out the practi...

We experimentally demonstrate the phase relations of 3-port gratings by investigating 3-port coupled Fabry-Perot cavities. Two different gratings which have the same 1st order diffraction efficiency but differ substantially in their 2nd order diffraction efficiency have been designed and manufactured. Using the gratings as couplers to Fabry-Perot cavities we could validate the results of an ear...
