SmartClass OLA-54/-55/-55M Optical Level Attenuators

Compact and rugged handheld attenuators for field or lab use.

The SmartClass OLA-54/-55/-55M Optical Level Attenuators are future-proof, improved variable attenuators for fiber system testing as well as installation, maintenance, and production of multimode fibers (OLA-54) and singlemode fibers(OLA-55/-55M). The OLA-55M Motorized Optical Level Attenuator provides in addition an implemented power meter for stabilized level controller applications.

The SmartClass OLA-54 and OLA-55 Optical Level Attenuators can be part of a SmartClass Optical Test Kits that contain all of the tools, including instruments and accessories, necessary to perform professional-grade power or loss tests in the field.

Highlights

  • Reduce testing time with a quick start operation, requiring no warm-up time
  • Provide excellent overall accuracy in use with hundreds of calibrated wavelength
  • Reduce the need for couplers and additional instruments in test setups.
  • Minimize insertion loss due to a special optical design

 

Applications

  • Emulate fiber loss for testing system dynamics
  • Simulate line loss for BER testing and amplifier testing (OLA-55/-55M)
  • System installation and maintenance of multimode fiber (OLA-54) and singlemode fiber (OLA-55/-55M).
  • Power level control for calibration test setups (OLA-55M)

 

Key Features

  • Robust, shock-proof, and splash-proof design for field operation
  • USB port for remote operation
  • Absolute and relative attenuation setting
  • Level controller function for direct setting of attenuator output level (OLA-55M)
  • 40 Gbps ready due to low Differential Group Delay
  • Traceable measurements to NIST/PTB standards for confidence in accuracy
  • 600 adjustable wavelengths for the OLA-54 and 400 adjustable wavelengths for the OLA-55/55M
  • Long battery operation time of >1000 h (OLA-54/-55)
