Luna 6415
Lightwave Component Analyzer
The Luna 6415 Lightwave Component Analyzer is a fast and simple-
to-use tool for testing passive optical components and modules.
The 6415 measures and analyzes the Insertion Loss (IL) and Return
Loss (RL) distribution, as well as length, working in either reection
or transmission mode.
The 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 6415 an ideal analyzer 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.
KEY FEATURES
APPLICATIONS
• Return loss (RL) and insertion loss
(IL) analysis
• Analyze components in reection
and transmission
• Trace distributed RL over length
of optical path
• Spectral analysis of RL and IL
• Detect and precisely locate
reective events and measure
path length (up to 200 m)
• Speed, resolution and accuracy
for optimizing production test
- 20 μm sampling resolution
• Spatial RL testing
• Automated IL test and analysis
• Skew measurement with sub-
picosecond resolution
• PLCs, waveguide devices, AWGs,
ROADMs, etc.
• Couplers, switches, beam splitters

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 (filter).
