JDSU PE3

Polarization Mode Dispersion Emulator

The JDS Uniphase Optical Delay instrument produces a controlled amount of delay by controlling the path length and thus the optical delay time of transmitted light in an optical fiber.This instrument can be used in a PMD emulation system or in a PMD interferometric measurement system to vary the path length in one optical branch of the system. It can also be used to vary the modulation phase of reflections for the testing of reflection effects on transmitters.

The insertion loss is optimized to be lowest at the center of travel.The display is factory set to read 0 ps at this point.

The instrument is available with single-mode fiber or polarization-maintaining fiber. The input and output FC/PC or FC/APC connectors are front-panel mounted. A zero-offset function allows the user to set the display to 0 ps at any path time setting. The optical delay is a programmable instrument that can be controlled from the front panel or by the GPIB and RS232 interfaces.
