OLS7-FTTH & OLS7-3
Triple
Wavelength Laser Sources
The OLS7-FTTH and OLS7-3 from AFL Telecommunications are handheld, rugged laser
sources 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,
both models may be used for fiber identification. The LASER output is stabilized to ensure
accurate test results per current TIA/EIA requirements.
The OLS7-FTTH and OLS7-3 feature a triple wavelength LASER output from a single
port and are easy to operate. Each wavelength may be transmitted individually at CW
or with user selectable modulated Tone. Also, each wavelength may be transmitted with
Wave ID. When transmitting with Wave ID, the OLS7 will also support transmitting pairs
of wavelengths in an alternating pattern and triple wavelengths in a sequential pattern.
Associated with each operating condition, the designated LED indicator will illuminate to
identify the currently enabled operating mode and emitted wavelength wavelength(s) along
with battery charge status and external power presence.
The OLS7-FTTH model is designed specifically for today’s FTTH network architectures
featuring a triple wavelength LASER output from a single port: 1310nm output for testing
in the upstream direction and 1490 or 1550nm, for testing in the downstream direction.
The OLS7-3 model features 1310/1550/1625 nm triple wavelength LASER output that is
used for single-mode applications, such as Telecom or CATV.
The OLS7-FTTH & OLS7-3 output ports are equipped with UCI based removable adapters
to allow the output connectors to be inspected and cleaned. Both models offer long battery
life from common AA alkaline batteries with external AC adapter available as an option.
The OLS7 is fully N.I.S.T. traceable.
