JDSU ORL-55 1
1 INTRODUCTION
The ORL-55 Test Sets
The handheld Optical Return Loss Test Sets
• ORL-55/21,
• ORL-55/22 and
• ORL-55/23
measure reflections on fiber optical systems.
Therefore the Test Sets provide a laser for several
wavelengths (see „Differences between the devices” on
page 2) and a Power Meter. Transmitter and receiver are
coupled internally by a optical coupler.
The Test Sets are especially designed for highest
performing testing of all optical signals and systems, i.e.
broadband, PONs, and Gigabit Ethernet. Battery
operation with four AA batteries and the robust, shock-
proof and splash-proof design allow a long operation
time in the field even under tough conditions. AC line
operation via a separate AC adapter and the USB
interface for remote control allow also comfortable use in
labs or production environments.
Technical Highlights
• Auto-Zeroing function for automatic dark current
adjustment
•Auto- function for automatic wavelength detection
• Measurement of modulated and unmodulated signals
• Universal adapter fitting APC connector systems
• Laser source with adjustable power level for
customized applications
• Optical isolators guarantee high stable output power
level.
