The OLS7-FTTH and OLS7-3 laser sources are cost-effective, rugged, handheld instruments 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 laser sources 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 tone modulation at frequencies of 270Hz, 330Hz, 1kHz and 2kHz. 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.

The OLS7-FTTH is designed specifically for today’s FTTH network architectures. This laser source features 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 may be used for single-mode applications, such as Telecom or CATV.
The OLS7-FTTH and 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 rechargeable NiMH batteries or external AC adapter available as an option.
The OLS7 is fully N.I.S.T. traceable.
