2x8 Coherent Mixer With Single-ended Photodetectors
-
This page defines the requirement of a special coherent receiver with 8 single-ended photodiode outputs, per customer request. The coherent mixer, consisting of two polarization-diversified 90deg optical hybrids, a polarizing beam splitter and a beam splitter, is exactly same as existing DP-QPSK coherent mixer, and therefore offering same optical performance.

40Gb/s Coherent Receiver
-
The integrated 40-Gb/s DP-QPSK receiver incorporates two 90° optical hybrids with four pairs of balanced photodetector (PD) and four linear TIAs into a single butterfly package. Unlike other technologies in which the polarization beam splitter (PBS) and/or the power splitter (BS) are not included, Optoplex’s receiver includes both of them with the optical hybrids, PDs and the TIAs to offer a fully integrated solution which will benefit users in terms of completely removing fiber routing and the skew management. The integrated receivers work at the symbol rate up to 12.8GBaud/s.
