Skim pemultipleksan pembahagian panjang gelombang (WDM) digunakan secara meluas dalam rangkaian teras metro fotonik. Dalam rangkaian WDM, kekangan kesinambungan panjang gelombang digunakan untuk membina nod geganti sahaja. Kekangan ini mengurangkan kecekapan penggunaan panjang gelombang setiap pautan. Untuk menambah baik perkara yang sama, penukar panjang gelombang optik semua (AO-WC) telah menarik perhatian sejak beberapa tahun kebelakangan ini. Khususnya, AO-WC ialah peranti utama kerana ia membolehkan penukaran serentak berbilang panjang gelombang lampu isyarat kepada panjang gelombang lain, bebas daripada format modulasi. Walau bagaimanapun, setiap AO-WC memerlukan pemasangan pelbagai sumber laser dengan lebar jalur yang sempit kerana lampu yang dipancarkan oleh sumber laser digunakan sebagai lampu pam apabila panjang gelombang lampu isyarat ditukar oleh proses pencampuran empat gelombang (FWM). Untuk mengurangkan bilangan sumber laser, kami mencadangkan AO-WC yang dipam jauh, di mana sumber laser lampu pam diagregatkan ke dalam beberapa nod geganti. Apabila permintaan untuk penukaran panjang gelombang daripada nod geganti tanpa sumber laser disampaikan, nod geganti dengan sumber laser menghantar cahaya pam melalui pautan optik. Skim yang dicadangkan membolehkan pengurangan bilangan sumber laser lampu pam. Di sini kami menganalisis herotan cahaya pam dengan menyebarkannya melalui pautan optik Kami juga menilai kesan hingar dalam penguat optik dan tidak linear dalam gentian optik menggunakan simulasi berangka yang menggunakan parameter perwakilan untuk rangkaian WDM praktikal.

Abstract: Wavelength division multiplexing (WDM) scheme is used widely in photonic metro-core networks. In a WDM network, wavelength continuity constraint is employed to simply construct relay nodes. This constraint reduces the wavelength usage efficiency of each link. To improve the same, an all-optical wavelength converter (AO-WC) has been attracting attention in recent years. In particular, an AO-WC is a key device because it enables simultaneous conversion of multiple wavelengths of signal lights to other wavelengths, independent of the modulation format. However, each AO-WC requires installation of multiple laser sources with narrow bandwidth because the lights emitted by the laser sources are used as pump lights when the wavelengths of the signal lights are converted by the four-wave mixing (FWM) process. To reduce the number of laser sources, we propose a remote pumped AO-WC, in which the laser sources of the pump lights are aggregated into several relay nodes. When the request for the wavelength conversion from the relay node without the laser source is conveyed, the relay node with the laser source transmits the pump light through the optical link. The proposed scheme enables reduction in the number of laser sources of the pump lights. Herein we analyze the distortion of the pump light by propagating it through the optical link We also evaluate the effect of the noise in optical amplifiers and nonlinearities in optical fibers using numerical simulations employing the representative parameters for a practical WDM network.

AB - Wavelength division multiplexing (WDM) scheme is used widely in photonic metro-core networks. In a WDM network, wavelength continuity constraint is employed to simply construct relay nodes. This constraint reduces the wavelength usage efficiency of each link. To improve the same, an all-optical wavelength converter (AO-WC) has been attracting attention in recent years. In particular, an AO-WC is a key device because it enables simultaneous conversion of multiple wavelengths of signal lights to other wavelengths, independent of the modulation format. However, each AO-WC requires installation of multiple laser sources with narrow bandwidth because the lights emitted by the laser sources are used as pump lights when the wavelengths of the signal lights are converted by the four-wave mixing (FWM) process. To reduce the number of laser sources, we propose a remote pumped AO-WC, in which the laser sources of the pump lights are aggregated into several relay nodes. When the request for the wavelength conversion from the relay node without the laser source is conveyed, the relay node with the laser source transmits the pump light through the optical link. The proposed scheme enables reduction in the number of laser sources of the pump lights. Herein we analyze the distortion of the pump light by propagating it through the optical link We also evaluate the effect of the noise in optical amplifiers and nonlinearities in optical fibers using numerical simulations employing the representative parameters for a practical WDM network.
