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
  • SC switchable adapter (mounted)
  • FC switchable adapter (spare)
