Description

The Multi-Channel Benchtop Polarization Dependent Loss Emulator (PDLE) offered by OZ Optics is a rugged and low-cost turnkey solution with high resolution and high dynamic range. This benchtop unit features motor controlled PDLE units with low insertion loss, low back reflection, low polarization mode dispersion (PMD), and a flat wavelength response. It can be configured with up to 4 individual motor-driven PDLE units in a benchtop setup or up to 16 channels in a full rack-mount unit. The system includes a color touch screen on the front panel and a USB interface on the back panel for easy operation.

The PDLE is designed to emulate polarization dependent losses caused by passive/active optical devices in an optical link, such as attenuators, modulators, array waveguides, fiber Bragg gratings, switches, fused couplers, and more. It enables accurate physical emulation of PDL in an optical system, allowing for quantification of available PDL budget margins.

When combined with other OZ Optics products such as a motorized variable attenuator, an optical switch, a polarization dependent loss meter, a polarized stable source, or a polarization controller, the benchtop PDLE greatly assists in defining and quantifying polarization dependent losses and other fiber impairments in fiber-optic networks.
