JW8301/JW8302
Fiber optic test platform for measuring insertion loss and return loss of simplex and duplex fiber optic cables
This loss meter is designed for testing insertion loss (IL) and return loss (RL) of passive optical components, including CWDM devices, multi-wavelength components, PLC splitters, and fiber optic jumpers. It features integrated red light or 850nm multimode light source functionality and supports various advanced capabilities, such as pedal switch, threshold determination, automatic multi-wavelength detection, system integration, and integration with PC software for advanced customization, enabling secondary development for tailored testing workflows and system integration.
Features
- Supports 2, 3, and 4-wavelength IL/RL testing
- Includes either a 650nm red light source or an 850nm multimode light source
- Automatic multi-wavelength testing and display
- Simultaneous testing of multiple selected wavelengths
- High-precision optical power meter mode with a test range of 3dBm to -75dBm
- USB and RS232 connectivity to meet diverse requirements
- Comprehensive threshold settings and alarm functions
- Optional integrating sphere configuration for the optical power meter
- External probe configuration available for testing bare fiber clamps
- Supports polarity sequence testing
- Simultaneous testing of duplex LC cables or cables with different interfaces
- Pedal switch for data upload
- Multiple operating modes, including OPM (Optical Power Meter), IL (Insertion Loss), RL (Return Loss), IL2 (Dual-Wavelength Insertion Loss), and ILRL (Combined IL and RL Mode)
