1.1  Product Overview

The 3662-20/3663-20 LASER LIGHT SOURCE 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 wave-
lengths: 1,550 nm (3662-20) and 1,310 nm (3663-
20).

Output Modulation (CHOP)

This function modulates a laser output (CHOP
mode, duty ratio of 50%). The modulation fre-
quency may be selected from among the following
options: continuous wave (CW), 270 Hz, 1 kHz,
and 2 kHz.
