1060-nm VCSEL-based 28-Gb/s ?? 4-channnel optical signal transmission beyond 500-m MMF using high-density parallel-optical modules

摘要

We demonstrate an error free 28-Gb/s × 4-channel parallel-optical link using Sn-Ag-Cu solder reflow-capable miniature 1060-nm VCSEL-based optical modules. As an alternative solution to PSM4, we achieved error free transmission in 50-micrometer-core MMF beyond 500 m, owing to a low chromatic dispersion at 1060-nm, when the modules are operated at a bit stream of 28-Gb/s 2-1 PRBS.
