We demonstrate a three-node quantum network for C-band photon pairs using 2 of 59 km deployed fiber between Fermi and Argonne National Laboratories. The are directed to nodes standard telecommunication switch the detection system is synchronized picosecond-scale timing resolution coexisting O- or L-band optical clock distribution system.We measure reduction coincidence-to-accidental ratio (CAR)...

This article describes the software creation and development of the computer. Fortran 4 was chosen for scientific and technical problems. They named the language based on Fortran 4 language RTL (Fortranreal time language) treated the allocation of programs in the memory, different kinds of record commands in registers, and instruction structures in memory. It treated the principles of control u...

Even though there are many testing methods for telecommunication systems very little has been said about test execution in distributed environments. This paper addresses this problem and proposes the implementation and test of telecommunication services on a CORBA-like platform. We present a test architecture for distributed systems and describe system components and test execution phases. An i...

Telecommunication networks are growing very fast. The user’s needs, in regards to new services and applications that have a higher bandwidth requirement, are becoming bigger every day. A telecommunication network requires early design, planning, maintenance, continuous development and updating, as demand increases. In that respect we are forced to incessantly evaluate the telecommunication netw...

Japanese electric power companies seek to maintain highly reliable telecommunication networks in order to protect, operate, and maintain electric power systems. Hence, such companies operate telecommunication networks that consist of various kinds of network elements, such as microwave radio communication systems, optical fiber communication systems, and communication line carrier networks. Int...
