Frequently Asked Questions
Quick answers to help you select and request this product.
What is the optical range of this version?
This version measures from -50 to +26 dBm. It uses an InGaAs detector and covers an OPM spectral range of 800 to 1700 nm.
How many calibrated wavelengths does it have?
Ten: 850, 980, 1270, 1300, 1310, 1490, 1550, 1577, 1625 and 1650 nm.
What accuracy and resolution does it offer?
The datasheet states OPM uncertainty of ±5%, linear resolution of 0.1% and logarithmic resolution of 0.01 dBm.
Which signals does the OPM identify?
CW, 270 Hz, 330 Hz, 1 kHz and 2 kHz. It also supports wavelength recognition and measurement storage.
What is the VFL range?
The advertised range is up to 5 km and depends on fiber conditions. It operates at 650 ±30 nm in continuous mode or pulsed at 1 Hz or 2 Hz.
What is the VFL power?
The datasheet offers 2, 10, 30 and 50 mW configurations. The specific power depends on the supplied configuration.
What does it check in RJ45 cables?
The standard function checks wire sequence and continuity with a range of up to 300 m. Cable tracing is optional. This test does not certify the link's transmission category.
How is it powered?
The datasheet specifies three AAA batteries as the standard power supply and a 3.7 V / 700 mAh lithium battery as an option. It has a Type-C interface. The stated nominal runtime is at least 120 hours in OPM mode, depending on configuration and conditions of use.
What warranty does it offer?
KONGIA 5-year warranty.
What should I check before use?
Do not look directly at the VFL emitter or into live fibers. Check the power configuration and equipment adapters before connection.
