Avanex and SHF Develop 40 Gbps Line Card Technology

Avanex and SHF Communication Technologies AG announced a 40 Gbps duobinary modulator-driver assembly aimed at simplifying the manufacturing of 40 Gbps line cards. The device combines an optimized SHF driver amplifier and the Avanex PowerBit 40 Gbps Intensity Modulator to enable at least five times longer transmission distances compared to the traditional intensity-modulated NRZ approach, and without dispersion compensation. The companies said the new 40 Gbps duobinary transmitter sub-assembly reduces the bandwidth requirements of electronics and modulators because of its higher spectral efficiency. http://www.avanex.com/http://www.shf.biz/
