Power-efficient 10G TOSA for DWDM SFP+ transceivers

September 15, 2011

CyOptics Inc., maker of Indium Phosphide (InP) optical chip and component technologies, announced a new series of 10 Gbps transmit optical subassemblies (TOSAs) for the emerging DWDM SFP+ transceiver market.

SoC for 40-Gbps DP-QPSK coherent designs

September 15, 2011

PMC-Sierra has taken the first major step towards evolving designs leveraging dual-polarization quadrature phase-shift keying (DP-QPSK) with coherent detection away from discrete electronic elements towards off-the-shelf system on a chip (SoC) devices. The company’s new PM6373 POLO 40G integrates SerDes, digital signal processing (DSP), analog-to-digital converter (ADC), OTN framing, and Forward Error Correction (FEC) functions for use in 40-Gbps designs. The obvious question, of course, is when PMC-Sierra plans to tackle 100 Gbps.
