Usage Notes
Follow these precautions to ensure safe operation
and to obtain the full benefits of the various functions.
A laser beam is output from the laser output
connector during operation. The laser beam
is invisible. To prevent eye damage, do not
look directly into the connector or look at it
through a magnifying glass while the power
is on.

Direct
sunlight
High temperature
High humidity
Dust
• Do not store or use the product where it could
be exposed to direct sunlight, high temperature
or humidity, or condensation. Under such conditions, the product may be damaged and insulation may deteriorate so that it no longer meets
specifications.
• To avoid damage to the product, do not allow
the product to get wet, and do not use it when
your hands are wet.
• Do not use the product where it may be exposed
to corrosive or combustible gases. The product
may be damaged.
• To avoid damage to the product, protect it from
vibration or shock during transport and handling,
and be especially careful to avoid dropping.
• The mating portions of the laser output connec tor ferrule and of the connector adapter are
high-precision machined parts. Make sure that
these portions are free of dust or other foreign
matter when connecting them. In particular, the
optical output connector ferrule requires meticulous care. If there is dust in the interface or a
scratch on the optical output connector ferrule,
the 3662-20/3663-20 may not satisfy performance specifications.
• After use, always turn OFF the power.
• Be sure to replace the cap to prot ect the device
from dust when the 3662-20/3663-20 is not in
use.
• The Battery replacement indicator appears when
battery voltage becomes low. Replace the batteries as soon as possible.
• Use the specified battery (LR6 alkaline battery)
only. Other batteries (manganese batteries, for
example) run out more quickly than alkaline batteries.

Handling Optical Fiber Cable
Follow the precautions below to prevent damage
to the optical fiber cables.
• Do not insert at an angle.
• Do not bend the cable at the neck o f the connector.
• Do not bend or twist.
• Do not pull forcefully.
• Do not allow cable to kink.
• Do not touch the end face (ferrule).

1.1 Product Overview
Overview Chapter 1
1.1 Product Overview
The 3662-20/3663-20 LASER LIGHT SOU RCE is
a Class 1 laser source used to measure the optical
loss of optical fiber cables. The laser source is
designed to be used with an optical power meter.
The laser source is available in two output wavelengths: 1,550 nm (3662-20) and 1,310 nm (3663-
20).
1.2 Features
Output Modulation (CHOP)
This function modulates a laser output (CHOP
mode, duty ratio of 50%). The modulation frequency may be selected from among the following
options: continuous wave (CW), 270 Hz, 1 kHz,
and 2 kHz.
