Modeling and simulation of next-generation multimode fiber links

TLDR

The paper develops an advanced multimode‑fiber‑link model to support the creation of next‑generation 50‑μm‑core laser‑optimized multimode fiber specifications that ensure desired performance levels. The model incorporates detailed representations of the laser, transmitter optical subassembly, fiber, connections, and receiver preamplifier, and provides an efficient formalism for computing the fiber transfer function and link‑output signal in any configuration. Using the model, the authors show that transmitter and fiber specifications can be derived that guarantee any desired performance level.

Abstract

This paper describes an advanced multimode-fiber-link model that was used to aid the development of Telecommunication Industry Association standard specifications for a next-generation 50-μm-core laser-optimized multimode fiber. The multimode-link model takes into account the interactions of the laser, the transmitter optical subassembly, and the fiber, as well as effects of connections and the receiver preamplifier. We present models for each of these components. Based on these models, we also develop an efficient and simple formalism for the calculation of the fiber transfer function and the signal at the link output in any link configuration. We demonstrate how the model may be used to develop specifications on transmitters and fibers that guarantee any desired level of performance.
