CSS1-SM Contractor Series Dual Laser
Light Source
The Noyes CSS1-SM from AFL Telecommunications is a palm-sized, cost-effective dual
LASER source designed for performing insertion loss measurements on single-mode
fiber optic links when used with an optical power meter. When paired with an optical fiber
identifier, the CSS1-SM may be used for fiber identification. The LASER output is stabilized
to ensure accurate test results per current TIA/EIA requirements. Weighing only 0.4 lb, this
light source is ideal for field use.
The CSS1-SM features 1310 nm and 1550 nm LASER output from a single output port
and is easy to operate. Each wavelength may be transmitted individually at CW or with
user selectable modulated Tone. The output port is equipped with UCI based removable
adapters to allow the output connectors to be inspected and cleaned. A large LCD display
with backlight shows emitted wavelengths [nm], tone frequency [Hz], and indicates a low
battery condition. The CSS1-SM offers long battery life from common AA alkaline batteries.
