“…The system model is applied to two types of channel architectures, namely one that uses a dedicated optical fiber for the quantum channel and one that uses dense wavelength division multiplexing (DWDM) to put the quantum channel together with the classical channels into one optical fiber (e.g., see Refs. [34][35][36]). In both cases, we assume that the fibers have an attenuation coefficient of 0.2 dB/km.…”

Due to its ability to tolerate high channel loss, decoy-state quantum key distribution (QKD) has been one of the main focuses within the QKD community. Notably, several experimental groups have demonstrated that it is secure and feasible under real-world conditions. Crucially, however, the security and feasibility claims made by most of these experiments were obtained under the assumption that the eavesdropper is restricted to particular types of attacks or that the finite-key effects are neglected. Unfortunately, such assumptions are not possible to guarantee in practice. In this work, we provide concise and tight finite-key security bounds for practical decoy-state QKD that are valid against general attacks.

“…We note that the classical channel was neither linked to the QKD system operation nor used for encrypted communication. More recent works [6,7] investigate different impairment sources on a more general level, including effects that occur when more than one classical channel is present, e.g. FWM.…”

“…The .implementation of ASK format for coherent systems requires the phase 'φs' to remain nearly constant. All external modulators have some insertion losses, a power penalty occurs whenever an external modulator is used; it can be reduced to below 1 dB for monolithically integrated modulators [13].…”

AbstrakUntuk memenuhi permintaan lalu lintas data yang terus tumbuh di aplikasi telekomunikasi, jumlah panjang gelombang jaringan serat optis tulang punggung jaringan telekomunikkasi dinaikkan. Pertumbuhan layanan internet yang eksponensial, kapasitas transmisi menjadi tantangan luar biasa bagi jaringan. Sekarang, system transmisi 10 Gb/s digunakan dalam aplikasi komersial. Dalam waktu yang sama, efek nonlinear seperti FWM, SRS, XPM, SPM dan dispersi juga meningkat saat jumlah panjang gelombang yang melewati system transmisi bertambah. Untuk analisis format modulasi efisien bagi DWDM dan system transmisi long-haul, kita akan memakai beraneka modulasi sistem DWDM. Kecepatan data maksimal format modulasi NRZ-OOK adalah 10gb/s, sedangkan untuk RZ-OOK adalah sebesar 50 Gb/s. Karena modulasi Z-OOK menggunakan lebar pita dua kali bila dibandingkan denan modulasi NRZ-OOK. Format maodulasi sebagain dinaiktarafan dari OOK menjadi PSK, pengaruh sinyal OOK terhadap sinya PSL hasil penaiktarafan harus ikut dipertimbangkan apabila menggunakan konversi panjang gelombang multikanal. Modulasi PSK juga ikut dianalisa. Kata kunci: komunikasi serat optis, DWDM, NRZ-OOK, spektrum, nonlinearitas AbstractTo meet the growing data traffic demands in the telecommunication applications, the number of wavelengths is to be increased in a fiber-optic backbone of the telecommunication network. The exponential growth of internet services, transmission capacity is a tremendous challenge to networks. Nowadays, 10 Gb/s transmission systems are being used for commercial applications. At the same time, the non-linear effects such as FWM, SRS, XPM, SPM, and Dispersion are also increased, when the number of wavelengths passing through the single fiber is increased. The analysis of efficient modulation formats for DWDM system and long-haul transmission system, we go for various modulations for DWDM system. The maximum data rate for NRZ-OOK modulation format is 10 Gb/s. For RZ-OOK the maximum rate is 50 Gb/s. Since RZ-OOK modulation uses twice the band width when compared to NRZ-OOK modulation. The modulation format is partially upgraded from OOK to PSK, the influence of OOK signals on the updated PSK signals must be considered when using multi-channel wavelength conversion. The PSK modulation is also analyzed.
