100Gb/s Coherent Receiver
Description
The integrated 100-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 32GBaud/s.
Optoplex’s integrated 100-Gb/s DP-QPSK Coherent Receiver is compatible with OIF’s Implementation Agreement (IA) for Integrated Intradyne Coherent Receivers (OIF2009.033.04). The actual mechanical dimension is 50 ´ 27 ´ 7.5 mm (shorter and thinner than OIF’s maximum allowable dimensions). The high-speed electrical interfaces (RF Outputs) uses co-planar waveguides (CPW) as proposed in OIF’s IA. The low-speed electrical interface (DC Control Pins) uses 40 pins and the same arrangement as specified in OIF2009.033.05 IA.
