New optical transmitter module slashes power consumption by 50%
Mitsubishi Electric Corporation has announced the coming launch of a 10 Gbps optical transmission device that cuts power consumption by 50% compared to conventional models used for high-speed large-volume data transmission between data centres.
Comprising an electro-absorption modulator laser (EML) coupled with a transmitter optical sub-assembly (TOSA), the module transmits up to a distance of 40 kilometres thanks to its high-quality signal performance. Mitsubishi Electric will commercially launch its new EML-TOSA, known as the FU-613REA, on October 31.
The module complies with the 10 Gbps Miniature Device Multi Source Agreement (XMD-MSA) and uses in CAN packaging suitable for mass production, replacing box-type packaging used in conventional models.

The increasing use of high-speed, large-volume optical transmission devices at data centres accounts for the consumption of considerable amounts of electrical power, so Mitsubishi Electric's new power-saving EML-TOSA module is expected to attract considerable attention.
With a power consumption of 0.6 W, the module uses approximately 50% less than that of Mitsubishi Electric's current FU-612REA model. EML operation at high temperatures allows the thermo-electric coolers to be downsized. The module's newly developed EML chip achieves a low power penalty (difference in power before and after transmission), high extinction ratio (optical output ratio between "on" and "off" modes) and high mask margin (standardised specification indicating performance of optical output waveform), resulting in the capability to transmit data up to 40 kilometres. Mitsubishi Electric’s CAN-type packaging is suitable for mass production, With light emission at a central wavelength between 1530 nm and 1565 nm, the device has an output power of -2 to +2 dBm. The operating temperature range is -5 to 85 degrees C and the power penalty after 40 km transmission is less than 1.0 dB (typ.). The extinction ratio is more than 10 dB (typ.) and the mask margin is more than 20% (typ.)
