Warning
Exposure to class 1M laser radiation is possible. Access should be restricted to trained
personnel only. Do not view exposed fiber or connector ends when handling optical
equipment.
 Ensure adequate cooling and ventilation as specified.
 The installation and operation manual should be read and understood before units are
put into use.
 Always replace protective caps on optical connectors when not in use.
 The typical connectors fitted are SC/APC 8°. Note: 8° angle polished connectors must be
used.
Cleaning
Use only a damp cloth for cleaning the front panel. Use a soft dry cloth to clean the top of the
unit.
Do not use spray cleaner of any kind.
Overloading
Overloading wall outlets and extension cords can result in a risk of fire or electric shock.
Use approved electrical cords.
Damage requiring service
Unplug unit and refer servicing only to Ascent Communication Technology qualified service
personnel.
Servicing
Do not attempt to service this unit yourself. Refer all servicing only to Ascent Communication
Technology qualified service personnel.
General Reminders and Warnings
Review these reminders and warnings before you inspect and clean your fiber-optic
connections.
Reminders
 Always turn off any laser sources before you inspect fiber connectors, optical
components, or bulkheads.
 Always make sure that the cable is disconnected at both ends and that the card or
pluggable receiver is removed from the chassis.
 Always wear the appropriate safety glasses when required in your area. Be sure that
any laser safety glasses meet federal and state regulations and are matched to the
lasers used within your environment.
 Always inspect the connectors or adapters before you clean.
 Always inspect and clean the connectors before you make a connection.
 Always use the connector housing to plug or unplug a fiber.
 Always keep a protective cap on unplugged fiber connectors.

 Always store unused protective caps in a resealable container in order to prevent the
possibility of the transfer of dust to the fiber. Locate the containers near the connectors
for easy access.
 Always discard used tissues and swabs properly.
Warnings
 Never use alcohol or wet cleaning without a way to ensure that it does not leave residue
on the endface. It can cause damage to the equipment.
 Never look into a fiber while the system lasers are on.
 Never clean bulkheads or receptacle devices without a way to inspect them.
 Never touch products without being properly grounded.
 Never use unfiltered handheld magnifiers or focusing optics to inspect fiber connectors.
 Never connect a fiber to a fiberscope while the system lasers are on.
 Never touch the end face of the fiber connectors.
 Never twist or pull forcefully on the fiber cable.
 Never reuse any tissue, swab, or cleaning cassette reel.
 Never touch the clean area of a tissue, swab, or cleaning fabric.
 Never touch any portion of a tissue or swab where alcohol was applied.
 Never touch the dispensing tip of an alcohol bottle.
 Never use alcohol around an open flame or spark; alcohol is very flammable.
AON126S 2.6 GHz CATV and SAT-IF Optical Receiver series is a cost-effective high-performance
optical network unit which is designed and optimized to work in traditional CATV and satellite
applications or for advanced Fiber-to-the-Home (FTTH) architecture networks. The wide RF
spectrum supports both the CATV spectrum and satellite IF spectrum up to 2.6GHz.
The AON126S optical receiver makes it possible for cable operators to protect their existing
network investments and continue the deployment of FTTH networks for internet and VoIP
delivery together with IPTV and Video On Demand systems.
The AON126S optical node designed with 1550 nm forward-path RF signals and optional
WDM which allows for a video overlay over FTTH network topology and incorporates a low-
noise optical receiver. An optional PON upgrade port combines these wide band 2.6 GHz CAVT
and SAT-IF signals across a 1310/1490 nm EPON/GPON network, providing MSOs with a
flexible platform to migrate from existing HFC systems to a PON FTTH network.

This chapter introduces AON126S setup and installation. Before installing the equipment,
please read this chapter thoroughly.
The AON126S is packaged in sheet metal housing. The top housing contains the Optical
connection ports and the bottom housing contains the RF connection ports.
Four Cabinet Mount Holes are equipped which allow the optical node to be pedestal
mounted.
On receiving your new AON126S unit, you should carefully unpack and examine the contents
for loss or damage that may have occurred during shipping. Refer to warranty registration if
loss or damage has occurred. The AON126S should consist of the following:

Page 10 of 13
The AON126S requires an external supply of 11 V DC to 16 V DC. The maximum power
consumption of the unit is 3 W. A universal 12 V DC power supply plug-pack is supplied with
the unit, and is suitable for 95 V AC to 265 V AC 50/60 Hz with selectable mains pins for
Australia, Continental Europe, United Kingdom and United States.
The AON126S is specified for operation between 0 °C to +50 °C. Ensure that the unit is
mounted in such a way as to permit airflow around the front and sides at all times.
The AON126S has four mounting holes to fix the unit to the inside of a wiring closet or meter
box. The AON126S is designed to be a flexible and environmentally-friendly unit and as such
can be mounted in a number of ways to suit individual setup scenarios; however it is
important to permit free air flow across the front and sides of the unit.
Warning
Exposure to class 1M laser radiation is possible. Access should be restricted to trained
personnel only.
1. Ensure that the unit is complete with all expected equipment
2. If you are mounting the unit in a wiring closet or meter box, do this before
connecting the optical and coaxial cables. Keep in mind appropriate clearances for
these cables, air flow etc.
3. Connect the RF OUT port to the RF signal output.
4. Optical Input Port: Connect to forward fiber with SC/APC connector
5. PON Pass Port: Connect to PON signal fiber with SC/APC connector.
6. Connect CATV+PON and PON Pass to the CATV Coaxial network and the ONU.
7. Connect power to the unit via the power port
8. Ensure that the Power Status Alarm LED is green. Off is no power.
9. Check that the Optical Status LEDs is on. Optical input power is within -12 ~ 0dBm
10. User can adjust the RF Output power by the adjustable attenuator: Output level
adjustment range of 0 to 20 dB.

POWER LED off
Ensure that the unit is connected to a suitable power source. The power adapter for this
equipment has an input of 220 V and an output of 12 V DC. If the STATUS LED is still off, the
unit is likely to be faulty and should be returned to Ascent Communication Technology for
repair.
OPT. IN LED showing red
The optical level entering the unit is too low or too high and must be adjusted externally to
the unit, for optimal performance.
If the optical level entering the unit is too high, it could cause permanent damage to the unit.
The signal should be disconnected and attenuated to an appropriate level, before
reconnection to the AON126S. If the unit does not function as specified it is possible that the
unit has been damaged and should be returned to Ascent Communication Technology for
repair.
No RF output
Ensure that a forward-path signal is present on the system, at the correct wavelength for the
AON126S to receive. If the signal is present, but not at the desired level, adjust the RF ATT
control.
Keep the optical connector clean, a poor link will reduce the RF output level.
