CHAPTER 1
Introduction to the Passive Optical Network
A passive optical network (PON) or Gigabit Passive Optical Network (GPON) is a point-to-multipoint (P2MP)
network that uses a combination of active transmission equipments and passive cable components to provide
network connectivity to end user's devices. This network is suitable for building access networks such as
fiber-to-the-home (FTTH), or fiber-to-the-office (FTTO), or fiber-to-the-company (FTTC) for providing
internet access by running fiber optic cable directly from an internet service provider to a user's home or
business. The PON technology is based on the ITU-T G.984 standard.
PON transmits Ethernet, Asynchronous Transfer Mode (ATM), and Time Division Multiplexing (TDM)
traffic. It consists of mainly two active transmission equipments, Optical Line Terminal (OLT) and Optical
Network Terminal (ONT). One of the main characteristics of PON is the use of passive optical splitters in the
fiber distribution network, enabling a single feeding fiber from the service provider’s central office to serve
multiple homes and small businesses.
The network path between the terminals is known as Optical Device Network (ODN), which comprises passive
optical components, such as optical fibers and passive optical splitters. The ODN provides optical channels
that interconnect the OLT to the ONTs. The optical fiber cables cover a distance of 20km to 30km.
A single optical fiber from the OLT connects to a passive optical splitter that is located near an end user's
premises. The optical splitter divides optical power into nseparate paths to end user. The number of optical
paths can vary from 2 to 128. From the optical splitter, a single-mode fiber strand is connected to each end
user's devices. Data is broadcast in the downstream direction and transmitted in the TDMA mode based on
timeslots in the upstream direction.

The data, voice, and video signals of an end-user devices are sent to ONTs. The signals are converted into
Ethernet packets and then transmitted over optical fibers to the OLT using the PON uplink ports on the ONTs.
Ethernet packets are forwarded to the upper-layer IP network using the uplink port on the OLT.

Cisco Catalyst PON Series OLT Overview
The Cisco Catalyst PON Series OLT is an aggregation device that is located at a service provider's central
office of the PON network. The main functions of a Cisco Catalyst PON Series OLT are traffic scheduling,
buffer control, and bandwidth allocation. The Cisco Catalyst PON Series OLT manages the network traffic
that is in the form of video, data, and voice signals in a PON network, and sends them downstream to the
Cisco Catalyst PON Series ONTs on the network. The Cisco Catalyst PON Series OLT also receives the
signals from the Cisco Catalyst PON Series ONTs located at an end user's premises and sends them to their
destination over the internet.
A Cisco Catalyst PON Series OLT can support up to 128 Cisco Catalyst PON Series ONTs per port. A Cisco
Catalyst PON Series OLT provides 8/16xPON ports, 4xG combo ports and 2x10G small form-factor pluggable
(SFP+) ports for uplink. A Cisco Catalyst PON Series OLT carries abundant services and flexible network
mode over one optical network, and is especially suitable for networks such as enterprise LAN, video
application, and high-speed internet.

Ports
PON Ports
The PON ports use multi-source agreement (MSA) type UPC or SC-PC fiber connector. The PON ports
support a bandwidth of 2.466 Gbps downstream and 1.244 Gbps upstream.
Console Port
The console port connects the Cisco Catalyst PON Series OLT to a PC running Microsoft Windows or to a
terminal server and uses the RJ-45 crossover cable. The RJ-45 console port connection uses the supplied
RJ-45-to-DB-9 female cable.
Auxiliary Port
The auxiliary port connects the Cisco Catalyst PON Series OLT to a host such as a Windows workstation or
a terminal server through the auxiliary port. The auxiliary out-of-band management port is a virtual routing
and forwarding (VRF) interface and uses an RJ-45 crossover cable.
1 G Combo Ports
A combo port is a combination of an SFP interface and an RJ-45 port. When the SFP interface is active, the
adjacent RJ-45 port is disabled. The 1 G ports use LC connectors for fiber-optic connections and RJ-45
connectors for copper connections.
10 G SFP+ Ports
The 10 G ports use LC connector cables for fiber-optic connections and RJ-45 connector cables for copper
connections. The SFP slots support only SFP+ modules. These SFP+ modules are field replaceable, and
provide uplink interfaces when installed in an SFP+ module slot.

Cisco Catalyst PON Series ONT Overview
The Cisco Catalyst PON Series ONT is an optical modem device that is integrated with powerful interoperability
and high performance. (An ONT is also referred to as Optical Network Unit [ONU]. ONT is an ITU-T term,
while ONU is an IEEE term.) The Cisco Catalyst PON ONT is located at an end user’s premises. The Cisco
Catalyst PON Series ONT connects to the PON network on one side and accesses the end user's devices in
FTTH, or FTTO, or FTTC service delivery architecture on the other side. The Cisco Catalyst PON Series
ONT communicates between the Cisco Catalyst PON Series OLT and the end-user devices.
In the upstream direction, a Cisco Catalyst PON Series ONT is connected to the optical splitter through the
PON port. The data, voice, and video signals from end user's devices are sent to the Cisco Catalyst PON Series
ONT. Using the uplink ports on the Cisco Catalyst PON Series ONT, these signals are converted into electrical
signals and transmitted over optical fibers to the Cisco Catalyst PON Series OLT. In the downstream direction,
the Cisco Catalyst PON Series ONT is connected to various end user devices using the G ports and provides
triple-play services such as high-speed internet (HSI), voice (VoIP), and video (IPTV and RF overlay).
