Product Description
The JDSU OLA‑55 is a SmartClass™ optical level attenuator for single‑mode fiber systems, engineered for 40 Gb/s and higher optical transmission testing. Housed in a handheld portable form factor, it features low differential group delay (DGD) and high‑precision calibrated wavelengths, enabling rapid simulation of fiber‑link attenuation in field installation, maintenance, and production verification scenarios.
Key Features
• High‑precision calibrated wavelengths: 1260‑1650 nm, supporting up to 900 calibrated wavelengths
• Low insertion loss: < 2.5 dB, maximum attenuation 60 dB, attenuation accuracy 0.8 dB
• Minimal DGD, suitable for 40 Gb/s and higher‑speed systems
• Fast start‑up with no warm‑up required, improving field testing efficiency
• USB remote operation and graphical UI, offering absolute/relative attenuation settings
• Multiple power options (dry cells, Ni‑MH batteries, AC adapter) with long‑life battery design
• Calibration compliant with NIST/PTB standards, ensuring measurement reliability
• Rugged shock‑ and dust‑proof construction for harsh field environments
