TL;DR
This study experimentally assesses the availability and fading effects of a 4.6 km urban free-space optical link, demonstrating high reliability with over 92% availability including slow fades, crucial for high-speed optical communications.
Contribution
It provides empirical data on outage probability and fading effects in urban free-space optical links over an extended period.
Findings
Link availability of 92% including slow fades
High-speed transmission of 500 Gb/s achieved
Identification of slow and fast fading effects
Abstract
We measured the outage probability of a 4.6-km urban free-space optical communication link over six days. High-speed power measurements reveal slow and fast fading effects, with link availabilities of 92% including and 99% excluding slow fades for 500 Gb/s transmission.
