Short reach optical interconnects must support higher data rates to manage the increasing needs of end users and the commensurate increase in storage and computation within and between data centers. VCSEL-based MMF links provide a power efficient solution which is achieved in part by maximizing the data rate per laser source. We design an archetype system to explore the challenges and benefits of...
We experimentally demonstrate 100Gbps PAM-4 transmission over 105m wideband MMF fiber at two separate wavelengths. The 107Gbps line rates allow a combined 200Gbps user rate with FEC. The link includes unpackaged 850nm and 940nm VCSELs designed for 25G operation and offline equalization and decoding.
