تصميم شبكة WDM-PON كوصلة أمامية تخدم شبكات الجيل الخامس

Abstract EN

We design in this research a passive optical network that works with wavelength division multiplexing technique (PON-WDM), to use it as fronthaul in 5G network between remote radio unit and the distribution unit.

The proposed technique is with 128 channels, each with a bit rate of 10 Gbps, and frequency spacing of 25 GHz.

The fiber optic cable length is 15 Km.

According to the recommendations of latest researches in optical field, we used duo binary modulation for transmitting the signal.

Optisystem software is used to simulate the proposed system.

The performance is analysed according to the result of bit error rate BER, Eye Diagram, and Q Factor.

Ourresult, for BER as average is BER= 10−14 , with Q Factor =7.6, and good eye digram, depending on the result, we can use this network as fronthaul in 5G network with achieving a high transmission bit rat.
