SIMPLIFIED PAM4

A modified optical PAM communication system using multiple laser sources to generate each amplitude level. The systems can be applied separately or in conjunction with another modulation system such as SDM, MDM, WDM, TDM, or other communication systems. In an embodiment, a PAM-4 system will increase data rate by a factor of two, but more complicated schemes using more lasers can be utilized to generate higher efficiency schemes.

Simplified PAM4 Signal Generation and Transmission

Join Optiwave for an informative & instructional webinar on simplified PAM4 signal generation and transmission. Theory, experimental results, and OptiSystem simulations will be presented and demonstrated. The components used for designing the PAM4 transmission system, along with their settings, will be discussed in detail.
