• GPON(Gigabit Passive Optical Networks)
• GPON supports Triple-play service, providing competitive all-service solution.
• GPON supports high-bandwidth transmission (2.5Gbps – 1.25 Gbps)
• GPON supports the long-reach (Typically 20 km) service coverage.
• GPON is the choice of the large carriers operators.
• GPON evolution: same Infrastructure can support new standards such: XG-PON(10Gbps-2.5Gbps), XGS-PON,
TWDM-PON (10Gbps-10Gbps) and near future > 40G & 100G

Why PON ?
Slide #6
Ø PON is a kind of passive optical network, broadband point to multiple-points architecture;
Ø PON is short for Passive Optical Network ;
Ø GPON consists of Optical Line Terminal (OLT), Optical Network Unit/Terminal
(ONU/ONT) and Optical Distribution Network (ODN) including Passive Optical Splitter.
GPON adopts Wavelength Division Multiplexing (WDM) technology, facilitating bi-directional
communication over a single fiber.
To separate upstream/downstream signals of multiple users over a single fibre, GPON adopts
two multiplexing mechanism:
– In downstream direction, data packets are transmitted in a broadcast manner;
– In upstream direction, data packets are transmitted in a TDMA manner.

Overview of Optical Access Network
This chapter describes the architecture of the optical access network.
Besides, this chapter describes various devices applied in the FTTx
network and you can get a knowledge of those devices applied in the
optical access network.

GPON mode of protection
This chapter shows the three main types of GPON protection

Type A: No protection
GPON Power Budget
This chapter describes GPON optical power budget.
Slide #16
Ø Power attenuation calculation of Optical splitter
Ø Input attenuation of optical splitter(<1dB):
∑(Power input) - ∑(Power output of all branch)
Input Output
1:2 optical splitter
2:N optical
splitter
Attenuation of 1:2 splitter: 3dB
Attenuation of 1:4 splitter: 6dB
Attenuation of 1:8 splitter: 9dB
Attenuation of 1:16 splitter: 12dB
Attenuation of 1:32 splitter: 15dB
Attenuation of 1:64 splitter: 18dB
Attenuation of 1:128 splitter:21dB

Output
Slide #17
Optical Power Attenuation
Ø Fibre attenuation relates to the fibre length
Ø The attenuation of fibre splicing point is
typically 0.1dB/02dB
Ø Other factors may cause attenuation, such
as fibre bending
About 0.5 dB max per km
for 1310nm and 0.3dB max
per Km for 1490nm
Table G.984.2 – Classes for optical path loss
Class A Class B Class B+ Class C
Minimum loss 5 dB 10 dB 13 dB 15 dB
Maximum loss 20 dB 25 dB 28 dB 30 dB
NOTE – The requirements of a particular class may be more stringent for one
system type than for another, e.g. the class C attenuation range is inherently
more stringent due to the use of a 1:2 splitter/combiner having a loss of
about 3 dB.
A class B+ OLT and ONU
can accept a total loss of 28 dB

Management and Service Provisioning
This chapter describes GPON management and
service provisioning.
Slide #21
GPON NMS provides all the management needs through an intuitive GUI for:
Ø configuration,
Ø Maintenance,
Ø Troubleshooting,
Ø Seamless integration into an OSS environment with northbound interfaces,
Ø ONU/ONT plug & play.
Ø Some vendors can support integrated OTDR.
NMS is connected with OLTs only
through a DCN

Finish the auto-configuration of OLT
Initial configurations (such as service system information
configuration, data configuration) are required on
terminals and then they can be put into use. To finish
these configurations, it is not cost-effective to carriers.
GPON supports zero configuration on
terminals and plug-and-play of terminals,
which is cost-effective.

l With guaranteed QoS, GPON ensures
the parameter indexes of TDM service,
such as end-to-end delay, Jitter and
error bit rate.
l OLT supports processing
TDM service in Native
and CESoP modes.
l With fixed upstream/downstream
frame structure, periodic
multiframes are transmitted in
GPON line. So, GPON can
transmit TDM service with first-
born advantage.
