LUNA 6415 Reflectometer/Lightwave Analyser – Production Test
The Luna 6415 is a fast and simple-to-use analyser for passive optical components and modules. The Luna 6415 measures and analyses the Insertion Loss (IL) and Return Loss (RL) distribution, as well as length, working in either reflection or transmission.
- 20 μm sampling resolution
- 20 m measurement range
- 6 Hz scan/acquisition rate
- 1.5pm wavelength accuracy
The Luna 6415 utilises optical frequency domain reflectometry (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 reflection or transmission with a single instrument.
Highlights:
- Return loss (RL) and insertion loss (IL) analysis
- Trace distributed RL over length of optical path
- Spectral analysis of RL and IL
- Detect and precisely locate reflective events and measure path length
- Speed, resolution and accuracy for optimising production test
- 20 μm sampling resolution
- 20 m measurement range
- 6 Hz scan/acquisition rate
Applications:
- Spatial RL testing
- Automated IL test and analysis
- Skew measurement with sub-picosecond resolution
- PLCs, waveguide devices, AWGs, ROADMs, etc.
- Couplers, switches, beam splitters

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