Title
A 70 Gbps NRZ optical link based on 850 nm band-limited VCSEL for data-center intra-connects.
Abstract
Short-reach optical interconnects among servers in data centers have attracted extensive studies recently. High capacity and low cost are two key problems for optical link. In this paper, we demonstrate a band-limited 850 nm vertical cavity surface emitting laser (VCSEL) based optical transmission system. The optical link realizes 70 Gb/s (65 Gb/s net rate) non-return-to-zero (NRZ) signal transmission over 11 m and 20 m OM4 multimode fiber (MMF), with the help of equalization for time domain interference elimination. The utilized VCSEL has a bandwidth of only 18 GHz, meeting the principle of low cost. The data baud rate in this paper reaches the highest value for an 18-GHz-class 850 nm VCSEL based optical link, to our best knowledge.
