An OLTS is an Optical Loss Test Set. According to the provided reference, it consists of two key items: a light source and an optical power meter.
Components of an OLTS
An Optical Loss Test Set is specifically designed to measure the total optical loss (attenuation) in a fiber optic link. It does this by utilizing its two primary components:
- Light Source: This component sends a stable light signal into one end of the fiber optic cable.
- Optical Power Meter: This component measures the strength (power level) of the light signal received at the other end of the fiber optic cable.
By comparing the power level sent by the light source to the power level received by the optical power meter, the OLTS calculates the total signal loss within the fiber link, which is crucial for verifying that the network will operate correctly.
