Return Loss vs . length measurement of a MEMS-based
optical swit ch. The first two ref lections are 5.0 mm apart. This
measur em ent was r ecorded with 20 micron spatial resolution.
The Luna OBR 5T-50 delivers fast, accurate
return loss, insertion loss, and length
measurements with 20 micron spatial resolution.
PERFORMANCE HIGHLIGHTS
• Industry-leading combination of measurement speed,
range, accuracy and resolution.
• 11.9 Hz acquisition rate
• 8.5 meter measurement range
• 0.015% length measurement accuracy
• 20 micron spatial resolution
• Streamlined Graphical User Interface + Software
Development Kit inclu ded
• Optimize throughput with customized interface
• Automatically locates reflective events and yields RL, IL
and event location
The Luna OBR 5T-50 is a fast, simple-to-use, low cost
precision reflectometer that measures the Insertion
Loss (IL) and Return Loss (RL) distribution of passive
optical components and modules including PLCs,
optical cables, connectors, switches, couplers and
more. This instrument utilizes swept-wavelength
interferometry to measure backscattered light as a
function of distance with -125 dB sensitivity and 20
micron spatial resolution. The OBR 5T-50 reduces cost
and complexity, while incre as ing throu ghp ut by
measuring RL, IL and length with a single instrument.
APPLICATIONS
• Fault location- Measure RL, IL, length
• Automated pass/fail inspection and reporting
• Precision optical cables and connectors
• PLC and waveguide devices
• Couplers, switches, beam splitters
• Skew measurement with sub picosecond resolution
• Real-time optical alignment
