PON Introduction

What is PON?

PON Introduction Passive Optical Network (PON) is a point-to-multi

point fibre to the premise network architecturewhere unpowered splitters are used to enable asingle fibre to serve multiple premises.

It consists of an OLT that is usually located in theservice providers central office and a number ofONUs located near the end users.

It is a form of fibre-optic access network andreduces the amount of fibre and central officeequipments as compared to the point-to-pointnetwork architecture.

GPON Technology Fundamentals

Gigabit-capable Passive Optical Network (GPON)is a PON which achieves higher bandwidth andhigher efficiency using larger, variable-length

packets. E.g. dynamic bandwidth allocation(DBA).

GPON offers efficient packaging of user traffic,

with frame segmentation allowing higher qualityof service for delay-sensitive voice and videocommunications traffic.

GPON Key Features Multi-plexing :

The GPON system uses the WDM technology to implementthe bi-directional transmission over a single fibre (a forcedtransmission mode).

Over a single optical fibre, to separate the Tx and Rx signals

of multiple subscribers, the GPON system uses the followingtwo multiplexing technologies:

The downstream data streams use the broadcasttechnology.

The upstream data streams use the TDMA technology.BY: Michael Kwaku Adongo 8

GPON Key Features Downstream principle :

Broadcast mode: The length of any downstream GPONframe is fixed to 125 us and the frames are broad cast to allthe ONUs. In this way, all the ONUs can receive the samedata. The ONUs differentiate the frames by ONU ID andfilters the frames to receive its own data.



10/29

GPON Key Features Upstream principle :

The upstream GPON data is transmitted in the TDMA mode. Theuplink is divided into different time slots, which are allocated toeach ONU according to the upstream bandwidth map field in thedownstream frames. Hence, all ONUs can transmit their own databased on a specific sequence and no conflict for competingtimeslots occurs.



11/29

Why GPON? Key Advantages:

Longer transmission distance: Transmission over optical fibresreaches the maximum of 20 km transmission distance. Higher bandwidth: downstream of 2.5 Gbit/s and upstream of

1.25 Gbit/s for each subscriber Optical split feature: The single optical fibre from the CO is split

to multiple drop optical fibres to save the resources.

Others: GPON supports the triple play service. It provides full-service

solution to solve the bandwidth bottleneck of twisted pairaccess, and to meet the requirement for high-bandwidthservices, such as high definition TV and live show. GPON is thebest choice for the triple play service.

Preferred by global big carriers

GPON Planning Basic guidelines Bandwidth categorization: Where are the subscribers located and

which bandwidth do they need? Duct network rollout: Based on detailed geographical information,

which existing ducts can be re-used and where should new ducts bebuilt?

Area definition: Which distribution and access areas have to bedefined?

Logical network structure: In which buildings should the OLTs andONTs be located and which logical distribution and aggregationstructure can be used between OLTs and ONTs? Which cascaded

bandwidth allocation is applied? Cable network rollout: Which physical drop, distribution and feeder

cable structure should be used? Where are the locations to splicefibres or to split the lightpath?

Capacity and cost calculation: Which capacities are required for allnetwork elements? How much does it cost?BY: Michael Kwaku Adongo 12

GPON Network Element Introduction Optical Network Terminal (ONT)

The SmartAX MA5612 is an industry-leading multi-dwelling unit (MDU) that provides multiple high-speed services for residential and enterpriseusers. It can be flexibly configured on a passive

optical network (PON) or a network deployed withtraditional category-5 cables, depending on eachcustomer's capacity requirements.

The MA5612 supports TDM E1 and PRI ports toensure seamless transfer of traditional PBX voiceservice and TDM leased line service to an IPnetwork.

Optical Distribution Network (ODN) Optical Distribution Frame

An optical distribution frame (ODF) is primarily used to connectand schedule optical fibres and optical cables. It is applicable tofibre intersections between an optical transmission network andoptical transmission devices as well as between optical cables inan access networks.

Optical Distribution Network (ODN)

Optical Splitter An optical splitter is a passive optical fibre tributary device that

connects an optical line terminal to an optical network unit. Itcan transmit packets using time division multiplexing (TDM) inthe downlink and gather packets using the time divisionmultiplexing access (TDMA) protocol in the uplink.

With the split ratio ranging from 1:2 to 2:64, the optical splitter

series can be installed in a connecting box, splice box, or opticaldivision box for fibre splitting, while the clearly-labelled opticalroute identifiers facilitate easy maintenance.
