Abstract
The recent deployment of ultra-high definition (UHD) applications rapidly increases data traffic in communication networks including datacenter networks. In datacenters, a large number of parallel optical links with multi-fiber push-on (MPO) connectors are employed for high-speed inter-switch communications. However, it needs precise alignment to completely eliminate air gaps in MPO connectors, and the air gaps increase noise owing to optical reflection. Here, we demonstrate that graded-index plastic optical fibers (GI POFs) increase tolerance to the connector reflection for high-quality data transmission because of its intrinsic mode coupling. This feature of the GI POFs will be advantageous to MPO-connector-based interconnect for data center applications in the upcoming UHD era.
