Description
Overview
The Viavi OLS-37 is a pocket-sized, single-mode laser light source designed for installation and maintenance of FTTH/PON networks. It features three laser diode stabilized wavelengths (1310, 1550, and 1490 nm) in a single compact instrument, making it ideal for testing single-mode 9/125 μm fiber optic networks with excellent price-to-performance ratio.
Key Features
- Three-wavelength single-mode laser source: 1310 nm, 1550 nm, and 1490 nm (FTTH/PON specific)
- Output power: -7 dBm with laser diode stabilization
- Switchable optical adapters: SC, FC, ST, LC connectors
- Tone generation at 270 Hz, 1 kHz, 2 kHz for fiber identification
- Auto-wavelength and Multi-wavelength modes (2 or 3 wavelengths)
- Short-term stability: ±0.02 dB (15 min); Long-term stability: ±0.05 dB (8 h)
- Battery-powered (AA) with up to 80 hours continuous operation
- Rugged pocket-sized design with large display and intuitive interface
Applications
- FTTH (Fiber-to-the-Home) network installation and testing
- PON (Passive Optical Network) deployment and maintenance
- Telecommunication network continuity checks and insertion loss measurement
- Single-mode fiber cable plant verification
Included Accessories
- 2 AA alkaline batteries
- Neck strap
- Belt bag
