No, a light source power meter cannot make phone calls; it is designed to measure optical power and test fiber optic links.

Purpose of Light Source and Power Meter (LSPM) Kits

A light source and power meter set is a matched pair of instruments used in fiber optics to measure optical power and verify link loss. The light source emits a stable, known optical signal, while the power meter measures the received power to calculate insertion loss or end-to-end fiber performance . These devices are essential for installation, commissioning, and maintenance of fiber networks, including cable TV, enterprise, carrier, and FTTH systems .

Advanced Features

Some modern LSPM kits, like the SLS-50 and OPM-50, include digital signal transmission between the light source and power meter. This allows the units to exchange test parameters, automatically identify wavelengths, and synchronize measurements over long distances . While this may resemble "communication," it is strictly for data exchange related to optical testing, not for making voice or phone calls.

Summary

• Function: Measure optical power, calculate fiber loss, and verify network performance.
• Digital features: Can transmit encrypted test data between units for accurate measurements.
• Cannot: Make phone calls, send SMS, or function as a telecommunication device. In short, while some LSPM kits have sophisticated digital communication for testing purposes, they do not have telephony capabilities and cannot make calls like a phone or mobile device .
