The EXFO FLS-135A is a portable singlemode light source engineered for fiber optic network certification, troubleshooting, and loss measurements. Dual-wavelength operation at 1310 nm and 1550 nm minimizes connector handling and accelerates field testing cycles. The instrument outputs continuous wave (CW) signals for power and loss measurements, plus 2 kHz modulation for fiber identification. Two output ports accommodate SC/PC or UPC/FC connectors.
