PMD and PDL Calibration Standards

Product catalog summary

Overview: The document provides detailed specifications and guidelines for polarization management components, specifically focusing on PMD (Polarization Mode Dispersion) and PDL (Polarization Dependent Loss) calibration standards. These components are crucial for high data-rate communications and require precise calibration standards due to the development of high precision test equipment.

Specifications:

DGD Calibration Standard: Mean DGD values are 0.314 or 0.628 ps for wavelengths 1500-1600nm. The material used is Quartz, with a calibration wavelength range of 1460-1620nm. PDL is typically < 0.05 dB, with a maximum of 0.1 dB. Insertion loss is < 0.5 dB typical, 0.7 dB max without connectors. The return loss is 50 dB without connectors. Temperature stability is DGD value × 0.0003/°C. The fiber type is SMF-28, with power handling up to 300 mW. Operating temperature is 23 ± 5°C, and storage temperature ranges from -40 to 80°C. Package dimensions are 2.28” (L) x 0.31” (W) x 0.31” (H).
SOPMD Calibration Standard: Mean SOPMD values are provided for various configurations. Material used is YVO4, with a calibration wavelength range of 1460-1620nm. PDL and insertion loss specifications are similar to the DGD standard. SOPMD temperature stability is SOPMD value × 0.0006/°C.
PDL Calibration Standard: PDL ranges from 0.05 to 2 dB by request, with calibration wavelength ranges of 1520-1620 nm or 1260-1360 nm. Insertion loss is PDL + 0.5 dB without connectors. Temperature stability is 0.001 dB/°C.
