Özet

Fiber üzerinden Radyo (R.o.F), ışığı kablosuz frekans sinyalleriyle (R.F) modüle edip kablosuz erişimi kolaylaştırmak

ve aktarmak için fiber optik kablo üzerinden iletebileceği bir teknoloji olarak kabul edilir. İletişim ağlarının

yüksek bant genişliğine olan talebinin artmasına göre (R.o.F) verimli ve pratik bir çözüm olarak kabul

edilmektedir. Bu makale de, RZ modülasyon formatlarının ve radyo frekansının performansını, iki kanallı dikey

boşluklu yüzey yayımlı lazer (VCSEL) olan ve belirli bir tek modlu fiberde (SMF) gönderilen belirli bir lazer

türünde olan bir lazer performansı önerdik. Dalga boyu bölmeli çoğullama (WDM) kullanarak. her bir kanalın

bit hızı 10 Gb / sn’dir, bu nedenle SMF’deki kümülatif bit hızı 20 Gb / sn’dir. İki kanal için simülasyonumuzdan

elde ettiğimiz deneyimin ortalama sonuçları Toplam Çıkış Gücü dBm (6.53388), Maksimum Q Faktörü

(6.67182), Minimum BER (3.43236 * 10-11), OSNR (dB) (29.6399) şeklindedir. Tüm ortalama değerler iyi ve kabul

edilebilir olmuştur. Tüm bileşenler arasında uyumluluk vardır. RoF’nin simülasyonu ve performans testi,

Optisystem 7.0 kullanılarak yapılmıştır.

SOFTWARE SIMULATION FOR 20Gbps RoF ARCHITECTURE OVER SSMF USING VCSEL AND RZ AS MODULATION FORMAT BASED ON WDM

Abstract

Abstract

Radio-over-Fiber (R.o.F) is considered as a technology where it can modulate the light with radio frequency

signals (R.F) and transmit through fiber optic cable to simplify and transfer wireless access. According to increasing

demand of high bandwidth of communication networks, (R.o.F) considered as an efficient and practical

solution. In this paper, we will have proposed and shown the performance of RZ modulation formats

and radio frequency with a specific type of laser that is vertical cavity surface emitting laser (V.C.S.E.L) with

two channels and sent the signals on one single-mode fiber (S.M.F) by using wavelength-division-multiplexing

(W.D.M). The bit rate of each channel is 10Gbps, so the cumulative bit rate on SMF is 20 Gbps. The average

results of our experience from our simulation for two channels are Total Output Power dBm (6.53388),

Max Q- Factor (6.67182), Minimum BER (3.43236*10-11), OSNR (dB) (29.6399). All the average values are good

and acceptable, we get on it because we using attractive components and there is compatibility between all

components. The simulation and performance test of RoF was done using Optisystem 7.0.
