The AFL OTDR is an advanced tool designed for efficient fiber optic testing, specifically developed to operate at wavelengths of 1310 and 1550 nm. With a robust dynamic range of up to 39 dB and an impressive event dead zone of just 0.7 m, this versatile instrument is ideal for open and closed fiber systems, allowing for maximum split ratios of 1:64. Its smart combination of OTDR modes—including SmartAuto, Expert, and Real-time—provides flexibility in a wide range of applications, from installation to troubleshooting. Equipped with a visual fault locator that operates at a wavelength of 650 nm, this device enhances convenience by offering two operational modes: continuous wave and 2 Hz flashing. The 4.3-inch display, featuring a resolution of 480 x 272 pixels, ensures clear visibility of critical testing parameters. Additional capabilities, such as Bluetooth and Wi-Fi connectivity, enable seamless data sharing, while its long-lasting rechargeable battery allows for over 12 hours of operation, ensuring you stay productive on the go.
