FTTH Technology Overview
The Calix network provides any combination of voice, video and data services for Fiber-To-
The-Home (FTTH) networks. Signals are distributed from a central office and driven by
active, powered transmitters over a fiber optic network (split up to 32 ways) to the subscriber
premises without any powered signal amplification. Return signals are passively combined
using optical components, without the use of powered signal amplification. The system
architecture will support a 32-way passive split up to a distance of 6 miles. Distances between
6 and 11 miles are supported with a 16-way split and distances of 11 to 12.4 miles are
supported via an 8-way split.
For reference, a block diagram of the Calix GPON Architecture is provided.
Voice Services
Voice Services are provided through the flexible architecture of the F5s DACs (Digital
Access Cross-connect) functionality. The shelf allows for Switched and Non-Switched T1
trunking through the Quad T1 modules. The Quad T1 modules are able to transport whole
or fractional T1s as necessary. The switched services adhere to the Telcordia GR-303
standard. The GR-303 capability allows for expanded line concentration to increase the line
density and still maintain industry standard blocking ratios. The Model 560 ONT receives the
signal and provides POTS (Plain Old Telephone Service) on binding posts for connection.

Video Services
Video Services may be provided by theses in two different formats.
RF Video
RF video is supported on a discrete path known as the VPON (Video Passive Optical
Network). The origin of the video comes from an RF Video HeadEnd. The RF signal enters
the optical transmitter and is multi-plexed into the GPON. The signal is converted to light
and “muxed” into the voice and data network using a Course Wave Division Multiplexor
(CWDM). The ONT converts the light back to the RF video signal. In this configuration, the
analog video service is totally independent of the Voice/Data/Digital video service
controlled by the shelf.
Switched Video Services (SVS)
SVS is an IP video solution. The video content is digitized and combined with the voice and
data traffic on the GPON. The origin of the video could be a digital feed by a content
provider or another source that can provide a digital video feed. The SVS signal is sent to a
data switch that combines this video signal with the data signal before forwarding it to the
shelf. The shelf combines the Voice, SVS and Data and converts it to light to be sent to the
ONTs via the GPON. The Model 560 sends the SVS and Data to the RJ-45 jack(s) for
output to the home.
Data Services
Data Services are provided by the system through the GPON module. The module has a
10/100/1000 Base-T Ethernet port which connects to a switch supporting the data and
Switched Video Services (SVS) content. The data is converted to light and sent to the ONTs
via the GPON. The Model 560 ONT converts the light back to the Ethernet signal and
outputs the signal on an RJ-45 jack.
Service Delivery
The F5 transport has at its core an ATM packet engine. To assist with Quality of Service
(QOS), different services are handled at different AALs (ATM Adaption Layers). Voice
Service is handled at AAL2, Dedicated Services are handled at AAL1 and Data Services are
handled at AAL5. The AAL5 layer incorporates prioritization of data packets, either High
(1), Medium (2) or Low (3) priority. Additional features (i.e. bandwidth) are provisioned on a
customer by customer basis through the CMS software.

Calix Model 560 ONT
The Calix Model 560 ONT provides the following primary features:
yIs designed to be mounted directly to the subscribers home (fully hardened
[weatherproof])
yCan be mounted in an internal utility room for small business applications.
yHouses the electronics that provides conversion between the fiber optic signals and
the electrical signals required by each subscriber.
yThe Model 560 ONT as standard can be provisioned for up to four telephone access
lines. Additional lines may be provisioned utilizing the expansion UVG module (4 or
8 additional lines) or Quad T1 module.
Important: The Model 560 ONT is capable of supporting up to 12 binding post
connections for telephone lines. In certain applications, a total of 20 lines may exist. In
these cases, external termination of these lines is required.
yTelephones may be connected remotely (up to 500 feet from the unit). The 500 feet
off-premises extension capability allows for remote telephone or other accessory
locations).
yAll off-premises extensions require additional surge protection.
yEach CATV signal exiting the ONT is optimized to allow for a four way split (or 16
total circuits) and 50 feet of coax cable prior to reaching the device (TV, etc.)
yPower to the ONT is provided locally.
yIn applications which require 8 or fewer telephony lines, a single UPS is needed to
ensure life line services can be maintained for an adequate period. For installations
with 9 or more lines, an external battery pack will be required to provide the
minimum 8 hours life line service.

Installation Assumptions
The following assumptions can be made when referring to the details of this installation:
yThat the fiber optic drop cable has been buried and will enter the unit from the
ground upwards.
yThat aerial drop installations are accommodated by looping the drop cable around
and underneath the unit.
yThat the drop cable incorporates a metallic shield for EMI protection.
yThat there is sufficient space available for mounting the uninterruptible power
supply, somewhere in the vicinity of the ONT.
Site Preparation
Before you mount an ONT to the side of the home or business, you must consider all
incoming and outgoing cables or wires and where they can most easily be routed.
WARNING! It is critical that you maintain the proper airflow in and around
the ONT in its final mounted location. Only surface mount the enclosure. Do
not install siding or other building material around the outside of the
enclosure. Doing so could create excessive heat and ultimately product
failure.
Before making a final determination as to the enclosures location, you need to consider the
proper clearances needed for swinging covers, latches or locks.
Note: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct

Proper Grounding Techniques
WARNING! Extreme care must be taken when attaching the ground
connectors to the utility (earth) ground rod. If the ground is interrupted or
disturbed in any way, an unsafe condition will exist.
The National Electrical Code (NEC), the Rural Electric Association (REA) and state/local
codes require that the ONT be properly grounded. A proper ground is one that bonds the
ONT to the buildings primary earth electrode. It is at this point that the power utility is also
bonded. The bonding conductor used must be a #6 AWG copper or equivalent. The NEC
grounding requirement stipulates that earth electrodes must conduct to earth with no more
then 25 ohms of resistance. If 25 ohms can not be achieved with a single electrode a
secondary electrode must be used and bonded together using a #6 AWG copper conductor
or equivalent. The secondary ground electrode must be spaced at least 8 feet away from the
primary electrode. The primary and secondary electrodes, once bonded together, become the
buildings primary ground point. The above named agencies do not require any additional
electrodes to be installed unless the ONT is located more then 20 feet away from the
buildings earth electrode.
If the ONT can not be installed within 20 feet of the building's primary earth electrode, an
additional ground electrode must be provided and bonded to the primary ground point of
the building. A #6 AWG copper conductor or equivalent bonding jumper must be used
between the earth electrodes and the ONT.
A suitable earth electrode can be a copper clad steel rod that is driven into the earth at least 8
feet deep or a metallic cold water pipe that is under ground for a distance of at least 10 feet.
If a water pipe is used as an earth electrode it must be no more then 5 feet from the outer
wall that the ONT is installed on.
All ground conductors are required to provide a low impedance path to the earth electrode.
The conductor must take the shortest and most direct path to the earth electrode and be free
of any sharp bends. If ground conductors are to be placed inside metallic conduit they must
be bonded to the conduit at both ends using a UL listed bonding type connector.

Installation Tips
WARNING! Only authorized service personnel should attempt to install
and/or repair this equipment. All problem discovery and repair procedures
are detailed to allow only sub-assembly or module level repair. Due to the
complexity of design, no one should attempt to make repairs at the
component level or make modifications to any circuit board. Improper
repairs can create a safety hazard.
Follow these tips when installing the ONT:
yKeep fiber optic cables and splicing equipment clean at all times. Use manufacturer
approved solvents and cleaning applicators. For more detailed information on Fiber
Optic Cable installation and maintenance, see Chapter 4 (see "Fiber Splicing
Techniques" on page 41).
yTake care to use the proper connectors for the application. Mismatching connectors
or the use of the wrong type of connector can result in the loss of optical power and
damage to the connectors. It is absolutely critical that the ONT is connected to a
known good earth ground. Failure to properly ground the unit during installation will
cause loss of services.
Important: Installations which utilize off-premises telephone extensions must also
incorporate a primary ground protection device for each off premises instance.
WARNING! This device does not incorporate a primary protector. If off
premises coax or telephone cable lengths exceed 140 feet (42.7 m), a
listed primary protector is required per the National Electric Code.
yWhen routing optic fibers, be careful to avoid bending the fibers beyond the
manufacturer recommended 1” (2.54 cm) bend radius. Exceeding the bend radius can
cause excess attenuation and possibly break the fiber.
yVerify all optical power levels before connections are made. If excessive loss is noted,
the use of an optical time domain reflectometer (OTDR) may be required.
yClean the fiber ends before making any connections.
ALERT! A Class I laser product is used in this equipment. Use an
optical power meter to identify active fibers. Never assume laster
power is turned off or that the fiber is disconnected at the other end.
A protective cap or hood must be place over any radiating bulkhead
receptacle or optical fiber connector.
Important: If grommets are inadvertently removed during the installation process, make
certain you reseal these openings prior to leaving the site. Openings in the ONT housing
can invite insects or rodents to nest inside the unit creating service delivery problems in
the future.
yThe electronics inside the Model 560 housing can be sensitive to electrostatic
discharge. Use of a static wrist strap is required.

yThe ONT relies on a quality earth ground in order to process signals properly. Make
sure you follow all applicable local codes for grounding.
yFor subscribers using data services, it is important to remember that all data wiring
done internally to the home is true CAT5 in design.
yFiber Optic Drop Cables (or simply drop cables) entering the ONT from
underground must be protected. Calix recommends the use of a riser tube for
protecting the drop cable.
