EXFO FLS-600 Light Source FLS-600-234BL 1310/1550/1625 nm APC-SC MFD2022

The EXFO FLS-600-234BL is a handheld singlemode optical light source delivering stable output at 1310 nm, 1550 nm, and 1625 nm for fiber optic attenuation and insertion loss testing. It features triple singlemode wavelengths (1310/1550/1625 nm) on a single APC-SC port, ideal for PON and DWDM network testing. The Auto-Switching Mode automatically cycles through wavelengths, saving time on multi-wavelength loss measurements. It offers up to 50 hours of battery life with built-in tone generation (270 Hz, 1 kHz, 2 kHz) for fiber identification.
