CHAPTER 1: SAFETY
MDU Solutions®– DVISf - Fiber Optic Digital Video Insertion System for Verizon FiOS®Networks – Installation & Operation Manual
1.1 Laser Safety
AVOID DIRECT EXPOSURE: EDFAs emit invisible laser radiation that may cause permanent eye damage. Avoid direct
exposure to the laser output. The output power of light with wavelengths in the infrared range may exceed +19 dBm (100 mW).
OPERATE EDFA WITH CONNECTOR INSTALLED: Operate the EDFA only with an optical ber connector installed in the
optical connector. EDFA output should never be activated without an attached ber. This will ensure that all light is conned
within the ber waveguide, virtually eliminating all risk of eye damage.
CONNECT FIBER TO DEACTIVATED EDFA: ALWAYS connect a ber to the output of the EDFA before the EDFA output is
activated.
DEACTIVATE EDFA OUTPUT TO CONNECT FIBER: EDFA output should be turned off whenever the optical connector cover
is opened and there is no installed ber.
NEVER LOOK INTO OUTPUT PORT: DO NOT look directly into the output port of the EDFA or transmitter to avoid damaging
your eyes. Fiber optic laser transmitter outputs at 1550 nm are totally invisible to the unaided eye and will cause permanent
damage. NEVER look into the output connector of the transmitter or EDFA or a ber connected to a transmitter or EDFA.
NEVER LOOK INTO FIBER END: NEVER look at the end of the ber to see if light is coming out. Fiber optic laser transmitter
outputs at 1550 nm are totally invisible to the unaided eye and will cause permanent damage. NEVER look into or use any
optical instrument to view the end of a ber that may be connected directly or via an optical splitter, to a transmitter or EDFA
that may be operating at any distance from the viewing end. Use extreme care with magnifying glasses, microscopes, etc.
USE POWER METER TO VERIFY OUTPUT: ALWAYS use an instrument such as an optical power meter to verify light output.
NEVER CLEAN CONNECTORS WITH ACTIVE LASER OUTPUT: NEVER clean an optical connector with optical power
present.
READ PRODUCT DATA SHEET: ALWAYS read the product data sheet and the laser safety label before powering or operating
the product.
USE APPROPRIATE EYE PROTECTION: Note the operation wavelength, optical output power and safety classications.
If safety goggles or other eye protection are used, be certain that the protection is effective at the wavelength emitted by the
device before applying power.
ATTENTION: PLEASE READ THE INSTRUCTIONS COMPLETELY AND CAREFULLY BEFORE
INSTALLING OR OPERATING THE UNIT! ALL OPERATION STEPS SHOULD BE CARRIED
OUT IN THE PRESCRIBED SEQUENCE! USING THE EQUIPMENT IMPROPERLY CAN CAUSE
SERIOUS DANGER FOR PERSONS OR DAMAGE THE DEVICES.

SYSTEM DESCRIPTION
2. System Description
2.1 In this Chapter
• “Model Description”
• “The DVISf Digital Audio/Video Insertion System”
• “Optical Insertion Operation”
• “Key Features”
• “Simplied Block Diagram of DVISf Product”
• “Available Hardware”
In this chapter we introduce the key features of the ATX Networks Digital Video/Audio Insertion System (DVISf) and describe
some attributes that make the DVISf device a powerful addition to the Verizon PON architecture.
2.2 Model Description
DVISf
The DVISf device contains up to 10 channels of MPEG2 encoding, integrated Optical transmitter and up to EDFAs. This
model is used in applications where up to 10 channels of in-house video are required in commercial sites such as stadiums,
hospitals and other health care facilities where in-house educational channels are implemented. The integrated optical ITU
Grid transmitter and associated EDFAs simplies the distribution of the inserted programs into the Verizon PON Network.

CHAPTER 2: SYSTEM DESCRIPTION
2-2 MDU Solutions®– DVISf - Fiber Optic Digital Video Insertion System for Verizon FiOS®Networks – Installation & Operation Manual
For full capabilities see “DVISf Specications” on page 12-1
2.3 The DVISf Digital Audio/Video Insertion System
The DVISf device is a network-edge local content insertion device for digital video networks where distribution and insertion is
optical. It encodes local baseband analog content into a digital format for use in a property provisioned with digital only TVs,
STBs or DTAs and a cable system with PON architecture where analog spectrum is not available.
Target applications include:
• Security or surveillance camera feeds (MDUs, retirement homes)
• Text/character generator or local information channel (hotels, conference centers, gated communities)
• Distribution of ‘in-house’ or private channels throughout a cable system plant or property (e.g., sports stadiums,
network studios)
All deployments of digital signals in a modern cable TV system are presented with challenges which did not exist in the
former analog deployments. Specic challenges are faced when MDUs and institutions within the cable plant require locally
inserted content which must be received by the installed base of cable TV set top boxes (STB). The DVISf unit can be used in
these properties to encode local analog video cameras, message boards, instructional and advertising channels into MPEG2
streams and insert the content into a blank EIA channel or perform digital drop and insert into pre-existing QAM carriers. The
exible architecture of the DVISf product makes it an ideal candidate for any number of programs that an MDU or similar
property is likely to require.
2.4 Optical Insertion Operation
The DVISf product supports installation into a PON topology. The equipment contains an integrated optical transmitter and up
to four EDFAs. The unit may be used to insert a single QAM channel into an optical network where the RF spectrum of the
target insertion channel has been left unoccupied. Optical channels from the broadcast transmitter and the DVISf narrow-cast
transmitter are combined using passive optical splitters. When the 1550 nm ITU band is received at the PON the DVISf QAM
channel will be present in an unoccupied EIA channel on the cable system. Availability of optical transmitters with a wide range
of ITU Grid channels allows placing the inserted optical carrier in relation to occupied 1550 nm spectrum.
2.5 Key Features
2.5.1 Flexible MPEG2 Digital Program Insertion
Designed for deployment in PON architectures, the DVISf product is capable of inserting digital programs into an EIA RF
channel where there is no pre-existing carrier on the broadcast Optical Network. The integrated QAM modulator is pre-set to
825 MHz for the Verizon PON Architecture.
2.5.2 Remote Monitoring Via SNMP
The DVISf product fully supports Simple Network Management Protocol (SNMP) which allows the monitoring of the built in
alarm points by a remote SNMP management console. The available DVISf MIB may be compiled into the remote Management
Console to provide notication of the triggering of any alarm either across a private network or the internet if available. Upon
triggering of a predened alarm, a trap is automatically sent by the unit to a listening SNMP management console.
The traps sent from the DVISf equipment are as follows:
• Internal Temperature beyond Threshold.
• Cooling Fan Failure.
• Video Status Changed (for each of up to 10 channels).
2.5.3 Simplied Mass Deployment and Backup with Conguration Export
The DVISf product allows the operator to export the programmed conguration as a le. The exported le may be used for
backup and archive purposes or to allow fast and easy deployment of multiple DVISf units with similar conguration. The le
may be imported to any number of units requiring similar settings, thus saving the time to manually program each unit before
deployment.
2.5.4 IPv4 Network Address Support
The DVISf unit uses IPv4 IP addressing and maybe congured with any valid IPv4 address to allow access from private
networks or from across the internet. For security against internet intrusion, the device forces assignment of a username and
password which may be changed at any time.

CHAPTER 2: SYSTEM DESCRIPTION
MDU Solutions®– DVISf - Fiber Optic Digital Video Insertion System for Verizon FiOS®Networks – Installation & Operation Manual 2-3
2.5.5 Powerful Management Interface
Management and conguration of the DVISf equipment is through a built-in web server which presents the conguration pages
in an intuitive tabbed interface. Access to the Management Interface may be congured to allow remotely connecting across
any private network or over the Internet if a connection is made available. For Internet security, a username and password
provides controlled access against unauthorized persons.
2.5.6 MDU Application Secure Enclosure
The DVISf equipment is constructed in a durable and lockable enclosure designed for the typical MDU wall mount installation
environment. Integral cooling fans allow the equipment to be installed and operate in a wide range of uncontrolled environmental
conditions where room cooling is not available. All controls and modules are securely located inside the cabinet.

3.5 Environment and Power
3.5.1 Airow and Cooling
Ambient temperature
The DVISf equipment must be installed in a room where the ambient air temperature does not exceed +122°F (+50°C). This
is a maximum temperature that must not be exceeded but the preferred temperature range is one where people feel most
comfortable.
Non-Condensing environment
The DVISf equipment must be installed in an environment that is non-condensing. This means that a relative humidity of
less than 95% must be maintained. Lower humidity is better and the preferred humidity range is one where people feel most
comfortable.
Fan control
The DVISf product is designed to operate to specication in an ambient room temperature of 0°C to +50°C (+32°F to +122°F).
Sufcient airow through the unit must be maintained regardless of the mounting location. It is imperative that other equipment
or materials of any type do not block free airow at the front of the DVISf unit.
The DVISf product does not contain air lters so there is no need to provide ongoing maintenance of lters.
3.5.2 Provisioning of Electrical Power
Power cord protection
Measures must be taken during installation to route or arrange the power supply cord to prevent physical damage to the
cord and to avoid the possibility of future damage occurring. The power supply cord shall be installed and routed such that,
throughout it’s length, the cord and it’s points of connection are not strained in any way. Route the power cord through the large
opening provided for A/V cable routing and over the right side of the cable management bar.
Power Cord Attachment:
The unit power supply cord shall not be attached to the building
surface, bundled with audio, video or RF coaxial cables, nor run
through walls, ceilings, oors and similar openings in the building
structure. The power cord may be secured against strain at the
DVISf cabinet by attaching it to the cable management bar with a
small cable tie as shown in the photo.
Provision of Electrical Power Outlet:
An electrical power outlet of appropriate type and rating shall be
provided near the location where the DVISf unit is installed such
that the provided power supply cord may be routed in an appropriate
manner, without the use of extension cords, between the receptacle
and the DVISf cabinet. Alternately, the DVISf cabinet shall be
installed in close proximity to an existing electrical outlet such that
the requirements of this paragraph are achieved.
IEC Power Input Cord
The power input receptacle is a standard IEC connector similar to that commonly used on computers and monitors. The power
cord provided with the DVISf product is a North American conguration with a NEMA 5-15 grounded plug for 110 VAC. If it is
necessary to operate the product on 220 VAC, the installer must obtain an IEC cord with a NEMA 6-15 grounded plug for use
in North America. This may be obtained from ATX Networks or locally.
Input Power Requirements
When installing the DVISf equipment, it is the responsibility of the installer to determine that sufcient capacity is available
in the electrical circuit feeding the unit to avoid overloading the supply circuit. Each DVISf model will require power to be
supplied from a properly grounded outlet. The installer shall determine that the power outlet, its wiring and receptacle is in
compliance with local and/or national electrical codes as applicable. The input power requirement is constant over the range
of input voltages. At higher input voltages, the current consumption is lower than it is at lower voltages where the input current
is higher.
Input Power: 165 Watts

3.6.1 Video Cable Recommendation
It is recommended to utilize double or triple shielded 75 Ω coaxial cables with RCA connectors or adapters for video signals.
UL approved coaxial cables that are in general use in Cable TV systems will usually be satisfactory. Observe re and smoke
rating of cables and the installation environment to ensure compliance with all local codes. Cables shall be routed such that
terminal connections are not strained.
3.6.2 Video Port Connectors
The MPEG encoders are provided with a BNC connector for video input. For convenience a BNC to RCA adapter is provided
on each video input port as this is a common requirement in many installations.
3.6.3 Video Input Levels
Video Input level is expected to be 1 volt P-P although a higher and lower signal voltage may be tolerated by adjusting the
video level control in the Management interface. See Brightness in “Video Output Conguration” on page 5-3 for a possible
work around for low level video.
3.6.4 Audio Cable Recommendation
It is recommended to utilize double or triple shielded 75 Ω coaxial cables with RCA connectors or adapters for audio signals.
UL approved coaxial cables that are in general use in Cable TV systems will usually be satisfactory. Observe re and smoke
rating of cables and the installation environment to ensure compliance with all local codes. Cables shall be routed such that
terminal connections are not strained.
3.6.5 Audio Port Connectors
The Audio connectors provided on the encoders are RCA type. Many adapter types are available to convert these RCA
connections to the type that may be encountered at a property.
3.6.6 Audio Input Impedance & Level
The audio input is high impedance unbalanced. Be sure to match the audio source to the DVISf audio connection. If balanced
audio is encountered it is often possible to obtain good results by using only the + side of the feed.
