The OLS2-Dual from AFL Telecommunications is a handheld, rugged 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 OLS2-Dual may be used for fiber identification. The LASER output is stabilized to ensure accurate test results per current TIA/EIA requirements.
The OLS2-Dual features 1310 nm and 1550 nm LASER output from a single output port and offers several modes of operation. 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 OLS2-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 OLS2-Dual output port is equipped with a UCI based removable adapter to allow the output connector to be inspected and cleaned. The OLS2-Dual offers long battery life from common AA alkaline batteries with external AC adapter available as an option.
The OLS2-Dual is fully N.I.S.T. traceable.

Noyes OPM 4 – Adds Wave ID & Set Reference
The Noyes OPM 4 optical power meter may be used to measure optical power in Premises, Telco, or Broadband fiber optic networks. When used with an LED or Laser light source, the OPM 4 also measures insertion loss of multimode or single-mode cables.
The OPM 4 offers Wave ID, automatic wavelength identification and switching, when used with the OLS 1 Dual or OLS 2 Dual or OLS 4 with Wave ID feature. Multiple test Tone detection is provided for fiber identification. The OPM 4 stores optical references for each calibrated wavelength. An easy to read Dual Wavelength LCD display with Backlight shows measured power [dBm or µW] or insertion loss [dB], calibrated wavelengths, tone signal [Hz], wavelength ID, and the battery charge status. In addition to being powered by two AA alkaline, the OPM 4 can be powered by optional AC adapter and/or rechargeable NiMH battery pack.
The OPM 4 optical input port accepts Noyes thread-on style adapter caps. Adapter caps are required for operation and must be ordered separately. The OPM 4 is fully N.I.S.T. traceable.
