Abstract: In general, a wavelength division multiplexed (WDM) communication system simultaneously pre-filters and combines groups of wavelengths with orthogonal polarizations to provide a pre-filtered, pair-wise orthogonal aggregate WDM optical signal. In particular, an orthogonally-combining interleaving filter multiplexer provides substantially orthogonal polarizations for odd and even channel wavelengths and simultaneously pre-filters and combines the orthogonally polarized odd and even channel wavelengths using interleaver optics. The orthogonal polarizations may be provided by orientation of PM input fibers or by a polarization rotator in the orthogonally-combining interleaving filter multiplexer.

Abstract: Embodiments of the present invention provide a manufacturing jig and a manufacturing apparatus for a temperature measuring sample. The manufacturing jig for a temperature measuring sample includes a first clamping mechanism configured to clamp the strip thermometer and adjust position of the strip thermometer, so that the best temperature measuring point at an end of the strip thermometer is at width center point of the coupling end of the printed circuit board. With the first clamping mechanism, the best temperature measuring point can be located at the width center point of the coupling end, so that alignment deviation of the best temperature measuring point in the width direction of the coupling end due to manual alignment is greatly reduced, which further ensures temperature measuring result of the temperature measuring sample are more accurate, and accurate control on actual pressing temperature of the pressing device can be achieved.
