We demonstrate a very high density 28-Gb/s × 24-channel CDR-integrated VCSEL-based optical transceiver module. The optical module achieves a very high data rate density of 1344 Gb/s/inch2 (2.08 Gb/s/mm2). An optical link employing the optical module achieved a jitter margin of 0.48 U.I. at a BER of 10−12 at case temperatures ranging from 31 °C to 70 °C with a very low link power of 13.5 mW/channel/Gb/s.
We introduce solder reflow-capable high-density parallel-optical modules for >100 Gb/s optical interconnects. Polymer-waveguide-coupled parallel-optical modules are also introduced with a unique mounting technology. 1060-nm 28-Gb/s InGaAs/GaAs VCSEL realizes a good signal quality at high temperature and error free for MMF transmission beyond 500m.
We demonstrate a novel architecture of mounting parallel-optical modules (POMs) onto an optical printed circuit board (PCB) through Sn-Ag-Cu-solder reflow process where precisely positioned stud-pins on optical PCB and guide holes formed on POMs were mated to maintain good optical coupling. We confirmed that fabricated 14-Gb/s × 12-channel POMs achieved a good transmission performance on a test environment...
