FL-3328 Insertion Loss & Return Loss Tester for SM & MM Fiber
The FL-3328 Series Insertion Loss & Return Loss Tester is a high-precision fiber optic test instrument designed for both singlemode and multimode fiber measurements. Equipped with advanced dual optical amplification and sampling technologies, it delivers industry-leading performance in insertion loss (IL) and return loss (RL) testing.
This compact and robust device integrates multiple laser sources, including 1310nm, 1490nm, and 1550nm for singlemode applications, as well as 850nm output on 50/125 µm fiber for multimode testing. An optional 650nm 10mW visual fault locator (VFL) further enhances usability in field or factory environments.
With a measurement range of up to 80 dB, a high-accuracy detection system (±0.1 dB), and built-in power meter with synchronous wavelength switching, the FL-3328 ensures reliable and efficient test results. Its dynamic LCD interface allows adjustable refresh rates with clear digital readouts, and the device supports RS-232 serial control with auto data storage, making it ideal for production lines and R&D labs.
