Current short-range optical interconnects capacity is moving from 100 to 400 Gb/s and beyond. Direct modulation of several laser sources used minimize bandwidth limitations current electrical components. This total provided either by wavelength division multiplexing or parallel optics; it important investigate on the ultimate transmission capabilities each source facilitate standards allow for future demands. High-speed four-level pulse amplitude at 25 GBd a 1.5 μ m vertical-cavity...
The impact of physical layer impairments in optical network design and operation has received significant attention the last years, thereby requiring estimation techniques to predict quality transmission (QoT) connections before being established. In this paper, we report on experimental demonstration a case-based reasoning (CBR) technique whether channels fulfill QoT requirements, thus supporting impairment-aware networking. validation cognitive estimator is performed WDM 80 Gb/s PDM-QPSK...
A direct and efficient method for evaluation of the error probability optical heterodyne receivers in presence phase noise is presented. closed form expression statistics decision variable, including photodetector shot thermal from electronic circuitry, derived. The analysis assumes simple integrating filters receiver based on a power series expansion filtered noise. calculated using saddle point approximation which numerically gives accurate results. optimal prefilter bandwidth best...
We report on migrating multiple-lane link into an L-band VCSEL-based WDM system. Experimental validation achieves successful transmission over 10 km of SMF at 4x14Gbps. Inter-channel crosstalk penalty is observed to be less than 0.5 dB and a around 1 dB. The power budget margin ranges within 6 7

Abstract Entropically secure encryption (ESE) offers unconditional security with shorter keys compared to the One‐Time Pad. Here, first implementation of ESE for bulk is presented. The main computational bottleneck a multiplication in very large finite field. This involves polynomials followed by modular reduction. A polynomial implemented based on gf2x library, modifications that avoid inputs vastly different length, thus improving speed. Additionally, recently proposed efficient reduction...
We report on the experimental performance of a case-based reasoning technique to predict whether optical channels fulfill quality transmission requirements, thus supporting impairment-aware networking. Validation is performed in WDM 80 Gb/s PDM-QPSK testbed.
