Handheld FTTH Fiber Optic Light Source — 1310/1550nm Precision Fiber Tester

Portable light source engineered for FTTH and communication testing. The unit offers two selectable output wavelengths to match customer requirements. For 650nm output it supports continuous wave (CW) and a 2Hz modulation mode; for the other wavelengths it provides CW plus selectable modulation at 270Hz, 1KHz and 2KHz. Designed for reliable measurements with highly stable output power and a consistent, stable output wavelength.
