Oz4
The ’Oz4’ is an 800Gbps Photonic Integrated Circuit (PIC) engine supporting four optical transmit lanes operating at 200Gbps per lane with PAM-4 modulation (106.25 Gbaud). It is based on Silicon Photonics (SiPho) technology and includes an integrated Continuous Wave (CW) laser, four low-loss Mach-Zehnder Modulators (MZMs), low-speed phase shifters, and power monitors.
The PIC dies are sold post-burn-in, and are both electrically and optically tested.
About this product
- Small footprint silicon photonics transmit side (Tx) PIC
- Integrated laser using DustPhotonics Low-Loss Laser Coupling (L3CTM) process
- Superior link budget due to low modulation insertion loss and excellent laser coupling efficiency
- Modulators are continuously self-calibrated using integrated power monitors
- TEC-less operation
- 90 Ω typical differential input impedance
- Compatible with immersion cooling
