Abstract
The choice of linear polarization modes in optical fiber is a key factor affecting performance of mode division multiplexing system (MDM). Firstly, an intensity modulation and direct detection (IM-DD) optical fiber transmission system based on hybrid mode division and wavelength division multiplexing (HMWDM) is designed. Secondly, the transmission characteristics of LP01, LP11, LP02, LP12 and LP21 five modes in the HMWDM system are simulated by Optisystem15.0 software. It was shown that when LP12 mode was multiplexed with LP01, LP11 and LP02, the Q factor of the signal carried by LP12 was 5-higher than that of LP21 multiplexed with the three modes in the same system. Then, four modes of LP01, LP11, LP02 and LP12 are multiplexed, and the simulation results show that the optimum value of the Graded-index multimode fiber (GI-MMF) core radius was 21 μm ∼ 22 μm with the Q factor above 7 when the core radius changed from 19 μm to 25 μm. Furthermore, the optimal value does not change with the transmission distance and the bandwidth of de-multiplexer. Finally, in the HMWDM system with a 21 μm-optimal-value core radius, the IM-DD method was used to realize the short distance transmission at 2.0 km with bit error rate (BER) below 10−9 and a rate of 80Gbit/s. The extension of the HMWDM system also be proposed.
