Procurement of upgraded light source for optical power meter
Upgraded light sources for optical power meters should offer multi-wavelength support, high accuracy, portability, and ruggedized design for reliable fiber optic testing.
Key Considerations for Procurement
1. Wavelength Support and Accuracy Choose a light source that supports the wavelengths relevant to your network, such as 850, 980, 1270, 1300, 1310, 1490, 1550, 1577, 1623, and 1650 nm. Multi-wavelength lasers or LEDs allow simultaneous testing and reduce errors when paired with compatible optical power meters, ensuring precise insertion loss and power measurements (Tempo Communications, AFL, VIAVI) . 2. Portability and Field Use For field applications, consider compact, lightweight, and durable units. Portable light sources with ruggedized, splash-resistant designs and long battery life are ideal for installation, commissioning, and maintenance of fiber networks, including FTTH, Ethernet, and service provider networks (Yokogawa, AFL) . 3. Compatibility and Kits Many suppliers offer kits combining optical power meters and light sources, which simplify testing and reduce setup time. Look for kits that include adapters, power supplies, and carry cases, and ensure compatibility with single-mode and multimode fibers (Tempo Communications, VIAVI) . 4. Advanced Features
- Wave ID or dual-wavelength identification: Reduces test time and technician errors.
- Continuous wave (CW) mode: Provides stable output for accurate measurements.
- Pre-configured tests: Simplifies operation for novice users while allowing advanced troubleshooting for experienced technicians (AFL, Yokogawa) . 5. Supplier Options
- Tempo Communications: Offers high-power and standard optical power meters with dual/triple wavelength sources and ruggedized kits .
- AFL OLS Series: Provides field-swappable adapters, long battery life, and wave ID features for efficient testing .
- VIAVI Solutions: Offers pocket-sized kits, wavelength-selective meters, and SmartClass Fiber test sets for lab and field applications .
- Yokogawa: Portable, user-friendly light sources and power meters suitable for a wide range of networks .
Recommendation
When upgrading, prioritize multi-wavelength capability, rugged portability, and kit compatibility. For field deployment, AFL or Yokogawa portable sources are highly recommended, while VIAVI and Tempo Communications provide comprehensive kits suitable for both field and lab environments. Ensure the chosen light source integrates seamlessly with your existing optical power meters to maximize efficiency and measurement accuracy.
