1.0 Introduction

This document details the installation and operation of the Navicor 1550 Externally Modulated 1RU
Transm itter (C- COR NA15T Series) and the Navicor 1 550 Erbium Doped Fiber Ampl ifier or EDFA (C-COR
NA25E Series). The transmitter converts RF signals to optical signals on optical fiber. The EDFA amplifies
an input from several optical fibers and outputs it to one optical fiber. For specifications other than those
shown here, consult the specification sheets for the individual model and consult C-COR as necessary to
define link performance.

1.1 Statement of Warranty

C-COR shall, at its expense, correct any defect in material and workmanship in products manufactured by
C-COR which may appear within the warranty period, as set forth herein. C-COR MAKES NO OTHER
REPRESENTATION OR WARRANTY OF ANY OTHER KIND, EXPRESS OR IMPLIED, WITH
RESPECT TO THE GOODS, WHETHER AS TO MERCHANT ABILITY, FITNESS FOR A P AR TICULAR
PURPOSE OR ANY OTHER MATTER.

The “warranty period” is as follows:

1. Dist ribution electronics, such as amplifiers, main line passives, and power supplies: five (5) years
from date of shipment.

2. AM fiber optic products: three (3) years from date of shipment.

3. Cable Network Manager (CNM™) network management software and associated equipment:
fifteen (15) months from date of s hipment. Net work Managemen t T r anspon ders (NMT): warr anted
as unit in which they are installed for a maximum of three (3) years. When installed in unit already
in the field, NMT will have remaining warranty of that unit, up to three (3) years and no less than
one (1) year.

4. Terminal, modem, and translator products: one (1) year from date of shipment.

5. Specialty goods manufactured in C-COR’s Equipment Service Center: CATV products: three (3)
years from date of shipment; DATA products: one (1) year from date of shipment.

6. All other goods: ninety (90) days from date of shipment.

C-COR’ s warranty shall not cover fuses, batteries, and lamps. It does cove r transistors and integrated circuits
to the extent that C-COR is warranted by the original manufactur er. Modifications or alterations of C-COR
products (including but not limited to installation of non-C-COR equipment or computer programs) except
as performed by C-COR or its authorized representative, will void this limited warranty.

1.5 Tools and Materials

Table 4 describes the tools, equipment, and materials that may be required to maintain the 1550 EDFA and
transmitter . Anyone performing the procedures in this manua l is expected to be familiar with the appropriate,
safe use of these tools. Tools or equipment with superior specifications may be substituted for those listed.

1.6 FDA/ANSI Classifications

The wavelengths of light typically transmitted through the optical fibers used in hybri d fibe r/coax ial cable
(HFC) architecture fall in the infrared band of the light spectrum and are not visible to the human eye. L asers
that generate beams of very intense light are classified according to their optical power. Optical receivers and
transmitters are, thus, classified according to the laser radiation associated with the respective optical module.
Refer to Section 1.2 for laser warnings.

Laser Class Power Comments

—

Considered to be incapable of producing damaging radiation levels
during operation or maintenance.

< 1mW Emits in the visible p ortion of the spectrum (400 to 700nm). N ormal

blink reflex (aversion response to bright light) provides adequate eye
protection.

Divided into subclasses 2 and 2a:

■ Subclass 2 lasers are not capable of emitting accessible radiation

greater than the Class 1 Accessible emission Limit (AEL) when

0.25 seconds is used as the exposure duration.

■ Subclass 2a lasers do not emit radiation that exceeds the Class 1

AEL for an exposure duration of ≤ 1000 seconds.

1mW–

500mW

Hazardous under direct and specular reflection viewing conditions.
Diffused reflection usually not a hazard. Not a fire hazard.

Divided into subgroups 3a and 3b:

■ Subclass 3a lasers are potentially hazardous only if the output is

collected and focused into the eye or onto the skin.

■ Subclass 3b lasers produce acute eye hazards even at the shortest

exposure duration.
