OLS1-Dual LED Light Source
The OLS1-Dual from AFL Telecommunication is a handheld, rugged LED light source
designed for performing insertion loss measurements on multimode fiber optic links when
used with an optical power meter. The LED output is stabilized to ensure accurate test
results per current TIA/EIA requirements.
The OLS1-Dual features 850 nm and 1300 nm LED output from a single output port and is
easy to operate with only a power button and a wavelength select button. Each wavelength
may be transmitted individually at CW or with Wave ID. When transmitting with Wave ID,
the OLS1-Dual supports transmitting pairs of wavelengths in an alternating pattern.
Associated with each operating condition, the designated LED indicator will illuminate to
identify the currently enabled operating mode and emitted wavelength(s) along with battery
charge status and external power presence.
The output port is equipped with UCI based removable adapters to allow the output con-
nectors to be inspected and cleaned. The OLS1-Dual offers long battery life from common
AA alkaline batteries with external AC adapter available as an option.
The OLS1-Dual is fully N.I.S.T. traceable.
