The LS310 Series of light sources is perfect for qualifying applications using fiber optics for the physical layer, including FTTx, CATV, PON, and long haul networks. These user-friendly instruments project a high- recision, semiconductor-grade laser for stable and accurate measurements. LS310 Series units work in conjunction with a Visual Fault Locator (VFL) for detecting bends, splices, and faults in optical fiber. Use the S310A/B in conjunction with an AE210, 230, or 270 Optical Power Meter to access new paired functions such as wavelength auto-ID. Dual-λ mode switches between two wavelengths rapidly, producing measurement data for both.
