Luna 6415
Lightwave Component Analyzer
The Luna 6415 is a fast and simple-to-use analyzer for passive
optical components and modules. The Luna 6415 measures and
analyzes the Insertion Loss (IL) and Return Loss (RL) distribution, as
well as length, working in either reection or transmission.
The Luna 6415 utilizes optical frequency domain reectometry
(OFDR) technology to measure backscattered or transmitted light
as a function of distance. Extremely high sensitivity and sampling
resolution (20 μm) make the Luna 6415 an ideal testing tool for
photonic integrated circuits (PICs) and silicon photonics. The Luna
6415 reduces the cost and complexity of test while increasing
throughput by measuring RL, IL and length in reection or
transmission with a single instrument.

OFDR Measurements for
Manufacturing Test
Measuring in reflection mode, the Luna 6415 measures return loss versus length. The
bottom plot shows the spectral content of the identified reflection event (grating).

NOTES
1. Distance between two sample points along the length axis in SMF-28.
2. Accuracy guaranteed via internal NIST-traceable HCN gas cell.
3. Range between strongest reflection greater than -60 dB and noise floor.
4. Noise floor return loss at half of maximum length.
5. Measured with 1 cm integration width.
6. Two way loss before backscatter reaches noise floor and IL
measurements are no longer possible.
7. Measured with 10 cm integration width.
