The Noyes SMLP4-4 is a dual-component fiber optic test kit combining an optical light source (OLS4) and optical power meter (OPM4-2D) for field certification of single-mode and multimode networks. The system delivers stable, accurate measurements across multiple wavelengths with automated wavelength detection and tone-based fiber identification. Technicians can perform insertion loss measurements, continuity checks, and hybrid network testing in a single integrated package.
Technical Specifications
The OLS4 light source provides wavelength coverage across both fiber types: 850 nm ± 30 nm and 1300 nm -10/+50 nm for multimode, and 1310 nm ± 20 nm and 1550 nm ± 20 nm for single-mode operation. Multimode output utilizes LED emitters (Class I per IEC 60825-1), while single-mode employs Class I laser sources compliant with FDA 21 CFR 1040.10/1040.11 and IEC 60825-1. Output power reaches -20 dBm at 62.5 µm multimode and 0 dBm at 9 µm single-mode. Spectral width spans 40 nm and 120 nm for multimode channels and 5 nm for single-mode.
The OPM4-2D power meter operates across 850 nm, 1300 nm, 1310 nm, 1490 nm, and 1550 nm wavelengths, displaying measurements in dBm, µW, or dB units. The meter features Wave ID automatic wavelength identification, tone detection supporting 270 Hz, 330 Hz, 1 kHz, and 2 kHz test frequencies, and reference storage for each calibrated wavelength.
Output stability reaches ± 0.1 dB over 8 hours (following 5 min. warm-up) and ± 0.05 dB over 1 hour (following 15 min. warm-up). Operating temperature range is -10°C to 50°C at 90% RH non-condensing. The kit operates up to 300 hours total, with the OPM4-2D delivering 30 typical hours and OLS4 providing 120 typical hours per charge using standard 2 × AA alkaline batteries.
– Key Features
• Dual wavelength LCD display with backlight and battery status indicator
• Four operational modes: dual wavelength sending ID, single wavelength sending ID, continuous wave, and modulated tone (single-mode only)
• Removable SC connectors; FC and ST adapters available
• Reference storage for automated insertion loss measurement per wavelength
• Optional rechargeable NiMH battery pack and AC adapter compatibility
– Typical Applications
Field testing and certification of single-mode and multimode fiber networks, hybrid SM/MM network validation, insertion loss qualification, and fiber continuity verification.
– Compatibility & Integration
Wave ID and tone detection enable automated wavelength switching and fiber identification when OLS4 and OPM4-2D operate together, eliminating manual configuration during field measurements.
