Real-Time 10GbE Data Transmission Over a Converged RoF Links and 96-GHz Wireless Bridge

Abstract

In this letter, we present a proof-of-concept of a real-time 10-Gigabit Ethernet (10GbE) standard data connectivity over a seamlessly converged intermediate frequency IF-over-fiber and millimeter wave links with remotely fed optical local oscillator (LO) signals. We demonstrate an error-free real-time transmission of $\pi /4$ -DQPSK-mapped 10GbE frames at 5-Gbit/s over $2\times 20$ -km single mode fiber and 20-m W-band (i.e., 96 GHz) wireless bridge. The 10GbE traffic is adjusted to the actual system capacity and transmitted using two parallel channels with a maximum rate of 1.25-GBaud per channel. We experimentally investigate and evaluate the impact of RoF and W-band links characteristics on the overall system performance. The obtained results demonstrate the potential use of the proposed system for the next generation agile and resilient access networks.
