Oclaro Announces 40G PM-QPSK Coherent Transponder

Oclaro introduced its third generation 40G PM-QPSK transponder featuring an integrated modulator, receiver and the industry's first single-chip ASIC solution for enabling coherent detection.



Oclaro said PM-QPSK modulation, coupled with coherent detection and digital signal processing, provides a cost-effective way for optical signals to reach longer distances with compensation for large amounts of optical impairments such as chromatic dispersion and polarization mode dispersion. The solution also provides a stepping stone to future 100G networks that will be based entirely on coherent detection.



Oclaro also announced the sampling of a new coherent receiver and 40G PM-QPSK modulator that enable customers to build their own coherent-based transponders or line cards for delivering higher performance and longer reach in the fiber optic network. http://www.oclaro.com
