The transmitter subsystem utilizes a Continuous Wave (CW) laser operating at a frequency of 193.1 THz (1552.52 nm) with a linewidth of 10 MHz and input power of 0 dBm. The laser output is modulated by a Mach-Zehnder Modulator (MZM). The MZM is driven by a Pseudo-Random Bit Sequence (PRBS) generator producing a non-return-to-zero (NRZ) signal at a data rate of 40 Gbps. The modulator is biased at the quadrature point to ensure linear operation.
These updates demonstrate Optiwave’s commitment to addressing emerging application domains—from low‑Earth‑orbit satellite constellations to autonomous vehicle LiDAR—while maintaining a strong foundation in conventional fiber‑optic communications. Here’s a minimal system to verify your setup:

Users can model single‑mode, multimode, multi‑core, and free‑space optical channels. The software handles time‑domain and frequency‑domain simulations equally well and provides automatic parameter sweeps and optimization to study the impact of specific device parameters on overall system performance.

The software accounts for the complex physical phenomena that degrade signals over long distances. It accurately models:
However, as transmission speeds increase (e.g., 40 Gbps and beyond), the fiber impairments become more pronounced. Chromatic dispersion (CD), polarization mode dispersion (PMD), and non-linear effects such as Self-Phase Modulation (SPM) pose significant challenges to signal integrity. This paper utilizes Optiwave OptiSystem, a leading optical communication design suite, to simulate and analyze these effects in a 40 Gbps DWDM environment, proposing a robust design for long-haul transmission.
