GPON FTTx Network Components

Q & A
System Overview

Fiber to the x (FTTx) is a collective term for various optical fiber delivery topologies that are categorized according to where the fiber terminates to provide the terminates with Applications using
GPON technology
that based on the optical fiber
high speed
,
security
, and
long distance
passive coverage that
save power

and active equipments
.

The FTTX system allows

video , Data , Voice

transmission over a secured and reliable infrastructure fiber network .
The system consists of
Aggregation Unit (OLT)
in the control room and
Optical Network terminal (ONT)
at the end user Desk with its different interfaces.

Splitter Ratio
= 1:32

Total bandwidth
=
BW Per user*No of users
Required No of GPON interface
=
Total BW / GPON BW

Each GPON Card has 8 GPON Ports



No of Splitters
= No.of Users / 32


No of GPON Ports
= No.of Splitters


No of ONT’s
= No.of Users

Design Example

E7-20 Ethernet Service Access Platform

Aggregation Units (OLT) Models

Modular 1RU chassis with a
100 Gbps
non-blocking backplane that delivers any mix of GPON,
Active Ethernet, 10GE, and GE
services.



The result: a simple, cost-effective network architecture that delivers advanced services and expanded network
capacity when you need it.

Assumptions
Splitter Ratio = 1:32
Each GPON Card has 8 GPON Ports
No of users = 300
No of ONT’s = 150
BW per User = 40 Mbps
Total BW = 300 * 40 = 12 Gbps
No of Splitters = 150 / 32 = 5
No of GPON Ports = 5
No of GPON Module = 1

What is FTTx ?

Fiber To The ……

FTTB (fiber-to-the-building):
Fiber reaches the boundary of the building, such as the basement in a Multi-dwelling unit

FTTH (fiber-to-the-home):
Fiber reaches the boundary of the living space, such as a box on the outside wall of a home.
FTTD (fiber-to-the-desktop):
Fiber connection is installed from the main computer room to a terminal  near the user's desk.

What Is GPON ?


Down stream Data (Broad cast Mode )

A passive optical network (PON) is a point-to-multipoint FTTP network architecture in which unpowered optical splitters are used to enable a single optical fiber port to serve up to
64 customers
.

Downstream signal 2.48Gbit/s
is coming from the central office is broadcast to each customer premises sharing a fiber.

Upstream rate 1.244 Gbit/s



Up stream Data (TDMA Mode )

What Is GPON ?


Encrypted traffic
for more security to prevent eavesdropping. “ listening to the private conversation ”

GPON supports the long-reach
(up to 20 km)
service coverage to overcome the obstacle of the access technology over twisted pair cables and reduce the network nodes.

Maximum physical reach:
20 km , 40Km
Split ratio:
1:32 and up to 1:64
