OLA-54/-55/-55M

Optical Level Attenuators

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

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 multi-mode fiber (OLA-54) and single-mode fiber (OLA-55 / -55M)
• Power level control for calibration test setups (OLA-55M)

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)
