platforms.
Typical applications include:
•Medium and long haul applications beyond the reach of 1310 nm
transmitters.
•Fiber dense architectures.
•Redundant rings.
•Broadcast layer transmission.
•Hub interconnects.
•DWDM architectures.
The modular design of the MAXLink and METROLink product lines offer the user a
number of advantages:
•The flexibility to add other plug-in modules as industry requirements change
without the need to replace equipment shelves, power supplies or status monitor-
ing equipment.
•The economic advantage of sparing plug-in modules rather than entire
subsystems.
•The ability to decrease the life-cycle cost of the equipment by means of an
increased numerical count of spare plug-in modules.
•Reduced service outages based on the ease of plug-in module replace-
ments in contrast to “all in one” type systems.
Typical deployments of the Optical Transmitter are shown in Figure1- 1.

Installation of the HOA 7000 Series
This chapter describes how to:
•Receiving and Inspection.
•Installing the Unit in the HLP 4200 Platform.
•Connecting the fiber cable.
2.1 Receiving and Inspection
When unpacking the unit, inspect the shipping container and equipment for damage. Save the
shipping material for future use.
If the container or the equipment is damaged, notify both the freight carrier and Harmonic Inc.
To protect the operator from potential injury and to protect the equipment from future damage,
do not perform any operational tests.
The HOA 7000 series is provided with the following accessories:
1. Product Manual.
2. Male GSK to Female F-Adapter.
3. Fiber cleaning kit.
4. Extra safety labels supplied for user cable(s).
Warning

Installing the HOA 7000 Series
2-2 Copyright © 2001 Harmonic Inc.
2.2 Installing the HOA 7000 Series into the HLP 4200
Platform
The HOA7000 Series Optical Amplifiers are designed for use in the HLP4200 Platform and
can be inserted into any available HLP4200 slot. The HLP4200 Platform is available in two
configurations, with a display (HLP4200 WD) or without the display (HLP4200 ND). If the
unit is to be installed in a HLP4200 WD Platform, the display/control panel must be lowered
prior to inserting the unit. If a HLP4200 ND Platform is being used, there is no display/control
panel to be lowered. Once the unit is seated in the platform, lock the unit into position by
tightening the knurled lock screw, as shown in Figure 1-4.
2.3 Connecting the Fiber Cable
•Direct viewing of the beam may cause serious eye damage and possible vision loss.
•Never operate system with fiber disconnected, an aperture open or a broken fiber.
•Do not view fiber ends or apertures directly with optical instruments (such as a magnify-
ing glass or an eye loupe).
•This Product is a Class I Laser with a Level 3B Hazard. The product is rated to 200 mW at
1550 nm ± 15nm.
2.3.1 Cleaning Fiber Optic Connectors
Dirty optical connectors are the leading source of poor performance in a broadband optical
fiber network. Dirty optical connectors lead to optical signal loss and reflections, that in turn
can result in serious carrier-to-noise (CNR) performance degradation and in some cases distor-
tion performance degradation.
Danger!
Invisible Laser Radiation when open or fiber disconnected. AVOID DIRECT EXPOSURE
TO THE LASER BEAM. Direct viewing of the beam can cause serious eye damage and
possible loss of vision.
Note!
Never operate unit with a broken fiber or with a fiber connector
disconnected.
!
Danger!
The fiber cable carries invisible laser radiation. AVOID EXPOSURE TO BEAM.
Never operate a unit that has a broken fiber or a disconnected fiber connector.

Installing the HOA 7000 Series
Harmonic recommends that all mating fiber connections be cleaned before making a
connection to an optical transmitter. If it is suspected that the optical connector of a
HOA module may have been exposed to contamination then properly clean the HOA
optical connectors before connecting optical fiber.
Each Optical Amplifier is supplied with an accessory kit that includes an SC/APC
fiber jumper. For optical installation, follow the steps below:
1. Make sure the laser disable switch is in the off/down position. The laser emission
indicator (Amber LED) is OFF.
2. Remove the plastic dust cover from the SC/APC connectors and store them in a
clean plastic bag for future use. Remove protectors from connectors.
3. Loosen the lock screw and move the safety shutter. See Figure 2- 1.
Figure 2-1 Safety Shutter
4. Carefully insert the plug into the optical connector at the rear panel of the
Optical Amplifier. Push the plug until you hear a click.
Caution!
Improper cleaning of an optical connector can do more harm than good. Never use a
clean air product to spray air onto the surface of an optical connector. Spraying air
onto an optical connector can cause condensation on the connector surface, leaving
water spots and trapping dust.
Caution!
Failing to wipe a connector with a dry lens paper immediately after wiping with
paper wet with Isopropyl alcohol can also lead to condensation on the connector.
Using low grade cleaning paper or other cloth to wipe an optical connector can
leave microscopic fibers on the optical connector surface.

6. Whenever a connector is opened, the plastic dust covers must be placed on both
ends. SeeFigure 2- 1. Typical fiber connections are shown in
Figure 2- 2.
