For singlemode system testing installation, maintenance, and
production.
The OLA-55M SMART Motorized Optical Level Attenuator is a variable optical
attenuator with a level controller mode in a single, rugged, handheld
instrument.
Highlights
- Absolute and relative attenuation setting.
- USB port for remote operation.
- Two operating modes: optical attenuator, and automatic level controller.
- Automatic stabilization of the output power with the automatic level
controller mode.
- Reduces the need for couplers and additional instruments in test setups.
- Direct setting of the output power with the automatic level controller
mode.
Applications
- Simulation of line loss for BER testing and amplifier testing.
- Power level control for calibration test setups.
Key Features
- The SMARTStar graphical user interface for fast, easy, and straightforward
operation.
- The SMARTEnergy power supply management system.
- A robust, shock-proof, and splash-proof design for field operation.
- One-handed operation in the field.
- Quick start operation, requiring no warm-up time and reducing testing
time.
JDSU SmartClass optical handhelds go beyond the
basics
With more than 100,000 optical handhelds already in use, JDSU
continues the success story with the SmartClass optical handhelds. The
SmartClass helps your network move to the next level of performance. SmartClass
optical handhelds encompass a new, intelligent, and next level product line for
testing all optical signals and systems, including broadband, PONs, and Gigabit
Ethernet.
All SmartClass optical handhelds provide:
- An extended number of calibration wavelengths for the highest performance
range in the industry.
- An intuitive graphical user interface for fast, easy, and straightforward
operation.
- An intelligent power supply management system.
- A belt bag for safe and hands-free operation and transport.
- Traceable measurements to international standards for confidence in
accuracy.
- A robust, shock-proof, and splash-proof design for field operation.
- Quick start operation, requiring no warm-up time and reducing testing
time.
The SmartClass OLA-55M (optical level attenuator) is the latest design of the
SmartClass product range. In this unit more functions have been added to the
well known SmartClass OLA-55, which is a future-proof instrument for system
testing, installation, maintenance, and production of singlemode fibers. Due to
minimized differential group delay (DGD), the SmartClass OLA-55M is also
suitable for 40 Gbps systems.
Automatic level controller mode
Most applications require
a defined power level rather than a certain level of attenuation. A standard
attenuator only allows the setting of an attenuation value. Against it, the
level controller mode of the SmartClass OLA-55M allows direct setting of a
precise and defined optical power level. It integrates the function of an
attenuator and a power meter and therefore avoids extra steps to adjust the
power level with a separate power meter. Being in this mode the attenuator is
automatically counterbalancing the changes of varying input power level and
provides a stable output level.
