Performance Investigation of CRZ Modulation Format in GEPON Fiber to the Home (FTTH) Network at 2.5G/bits for 200 ONU's

The work in this paper presents simulation of CRZ modulation format in a 200 subscribers at 2.5Gbps bit rate Gigabit Ethernet Passive Optical Network (GEPON) FTTH network. A link design for 1:200 splitter is used as Passive Optical Network (PON) element which creates communication between central offices to different users. A booster amplifier is inserted after optical fiber which decreases the value of BER. The simulation result of Bit Error Rate (BER) is found to be 9.2791e-9 at 2.5G/bits systems for CRZ modulation format. Sharp increase in BER occur if data rate increasing up to 5Gbps.
