Ultra low power consumption operation of SOA assisted extended reach EADFB laser (AXEL)
We propose a novel structure to reduce the power consumption and extend the transmission distance of a 10-Gbit/s, 1.55-µm EADFB laser. The power consumption is reduced by 1/2 and the transmission distance is extended.
Compact and low power consumption 1.55-μm electro-absorption modulator integrated DFB-LD TOSA for 10-Gbit/s 40-km transmission
We first report a low power consumption (under 0.18 W) and a wide temperatur range (−5 to 75 °C) operation of 1.55-μm un-cooled EA/DFB-LD coaxial-type TOSA in 10-Gbit/s 40-km transmission.
