摘要：Global market forecasts predicted that by 2020,
more than 26 billion internet devices and connections universally
interconnected will require nearly 3 times the data traffic
generated when compared to the year 2015. The increase in data
traffic, demands for enormous bandwidth capacity. The potential
to deliver 10 Gbps of huge data to individual businesses and
households will be of paramount importance and a challenging
issue for the present day service providers. An intensive study is
carried out for the Fiber-To-The-Home Passive Optical Network
(FTTH PON) for their use in the optical communication, due to
their high data rates and more bandwidth. The current evolution
of Next Generation-Passive Optical Networks Stage 2 (NGPON2)
network is the primary key technology for the growing
demands of higher bandwidth and transmission of the data to the
subscribers present in the access network from the service
providers. Time Wavelength Division Multiplexing PON
(TWDM-PON) architecture is the viable essential solution for
NG-PON2 which provides more bandwidth for bidirectional
transmission. This article proposes a design for extended reach
TWDM-PON based on reflective semiconductor optical amplifier
(RSOA). The exclusive feature of the RSOA is the wavelength
conversion, which replaces the transmitters in the subscriber
end. The Quality of Service (QoS) performance is critically
analyzed for different optical modulation formats in proposed
extended reach TWDM-PON using RSOA. The TWDM-PON
using RSOA is simulated and investigated for different
photodetectors. The analysis is also carried for various distance
and data rates. The results exhibited that APD receivers have
better performance of minimum bit error rate obtained is 10-11
and minimum Q factor is 6.2 when compared with PiN receivers.
The comparative analysis of different modulation formats shows
that the Carrier Suppressed Return to Zero- Differential Phase
Shift Keying (CSRZ-DPSK) gives the best performance for
longer distance and large data rates and Return to Zero(RZ)
gives the least performance.
