Description
The LS Series Laser Source is a compact and stable light emitter specifically designed for fiber optic continuity and loss testing. Ideal for field technicians and lab professionals, it enables accurate identification of fiber faults and performance verification across single-mode and multi-mode networks.
This series supports wavelength-identification digital encrypted protocol, ensuring precise recognition and seamless communication with power meters. It offers the flexibility of either two wavelengths on a single port or four wavelengths across two ports—making it adaptable to a variety of fiber testing scenarios including FTTH, LAN, and telecommunications infrastructure.
Designed with convenience in mind, the LS laser source includes features such as automatic power-off, a bright backlight for low-light environments, and multiple modulation frequencies (270 Hz, 1 kHz, 2 kHz) for tone generation. Its lightweight and rugged design make it ideal for field operations, while its consistent output power and excellent short- and long-term stability ensure trustworthy results in every measurement.
With models tailored to specific needs—ranging from standard telecom wavelengths (1310/1550 nm) to multi-mode applications (850/1300 nm)—the LS Series is a powerful and reliable tool for precise optical signal testing in modern fiber optic networks.

Two or four wavelengths output models
High output stability (±0.02 dB short-term)
Compact and portable design (only 180g)
Digital wavelength-identification protocol
Auto power-off function and backlight
Multi-frequency modulation: 270Hz, 1kHz, 2kHz
Available with FC/PC and SC/PC adapters
