Abstract

We investigate the performance VCSEL based 400G transmission over OM3 multimode fibers (MMF) that are TIA- 492AAAC compliant using 4-level Pulse Amplitude Modulation (PAM-4) standardized in IEEE 802.3cm. We analyze the relationship between fiber differential mode delay (DMD) tilt, fiber effective modal bandwidth (EMB), and bit error ratio (BER). We demonstrate that fiber tilt is not a reliable indication that fiber performance will be optimized based on directional barring. It is affirmed that EMB and BER are more favorable considerations for fiber communication performance.
