Simple PMD-insensitive OSNR monitoring scheme assisted by transmitter-side polarization scrambling.
Recently, degree of polarization (DOP) of light has been utilized as a parameter to monitor optical signal-to-noise-ratio (OSNR). However, in the presence of polarization-mode dispersion (PMD), when using DOP to determine OSNR, OSNR is always underestimated due to the depolarization effect induced by PMD. In this paper, we propose and experimentally demonstrate a simple PMD-insensitive OSNR mon...
متن کاملBit-pattern-dependent polarization rotation in first-order PMD-compensated WDM systems
We demonstrate both numerically and experimentally that the phase-change due to fiber nonlinearities induces a bitpattern-dependent rotation of the state-of-polarization which translates to uncertainty in the principal states of polarization. This effect severely limits the performance of the first-order PMD post-compensation and suggests the use of in-line compensators. Our simulation shows th...

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...
15 صفحه اولBit-by-bit optical code scrambling technique for secure optical communication.
We propose and demonstrate a novel bit-by-bit code scrambling technique based on time domain spectral phase encoding/decoding (SPE/SPD) scheme using only a single phase modulator to simultaneously generate and decode the code hopping sequence and DPSK data for secure optical communication application. In the experiment, 2.5-Gb/s DPSK data has been generated, decoded and securely transmitted ove...
متن کاملCombined Precoding and Volterra Equalization for the Mitigation of Fiber-Optic Nonlinear Channel Impairments
We investigate the performance of a combined Tomlinson-Harashima precoding (THP) and a Volterra nonlinear equalization (VNLE) in a nonlinear fiber-optic communication system aiming at a data rate of 100 Gbits/sec. THP-VNLE is compared with a feed-forward VNLE and a combined VNLE decision-feedback equalizer (DFE) by means of performance and computational complexity. Two different transmission sc...
