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 .
