Abstract

We investigate the temperature dependence of the primary factors determining link performance- relative intensity noise (RIN), chromatic dispersion (CD), and the mode partition noise (MPN) of vertical cavity surface emitting laser (VCSEL)-based multimode fiber (MMF) links through an analysis of the bit error rate performance of the links and a comparison with our end-to-end analytic link model. The statistical fluctuations of VCSEL mode power depend on VCSEL temperature and may lead to link failure at specific temperatures due to MPN. We, therefore, examined the link performance for three 150-m OM4 grade MMFs for a wide range of VCSEL temperatures using automated methods. MPN was found to remain stable over temperature for the devices studied; furthermore, RIN and CD were found to be the dominant factors determining the link performance, while MPN was found to be insignificant for the links investigated.
