LCM Launch Condition Analyzer


The LCM Launch Condition Meter is a convenient benchtop instrument for analyzing characteristics and geometry of optical fibers. Use Santec's software to scan and easily plot both the near-field and far-field patterns. Compare to standard launch templates such as the IEC 61280-4-1 Encircled Flux standard. The LCM can be equipped with two internal LEDs with 850 nm and 1300 nm wavelengths. Internal 105/125µm, 0.22NA fiber allows for overfill testing in most applications. The optical interface of the instrument accepts all standard 2.5mm ferrules. Other connector sizes are available upon request.

Near-field Measurements
Using the LCM-100 to perform nearfield measurements one can analyze fiber optic loss sources for various launch condition requirements such as: Encircled flux, 70/70, andAS100. The nearfield measurement can also be used to analyze multimode fibers for core size and refractive index profile.
Far-field Measurements
The LCM-100 can perform far-field measurement of light distribution exiting a fiber. This analysis can yield the numerical aperture of a fiber. The far-field measurement can also be used to verify proper launch conditions for military standard launches such as AS100 orAS62 specified in ARP5061.
Auto-alignment and Focusing

Using the auto alignment and focusing feature of the LCM-100 system, a technician can easily verify that the system is properly focused and aligned to yield accurate and repeatible nearfield measurements.

Mode Field Diameter Measurements

Using the far-field scanning apparatus of the LCM-100 system, the mode field diameter can be measured for single-mode fibers per the reference method as defined in IEC 60793-1-45.
