Mitsubishi Electric’s new 10Gbps EML-TOSA transmitter module cuts power consumption by 50%  

Tokyo-based Mitsubishi Electric Corp says that at the end of October it will commercially launch a 10Gbps optical transmission device that cuts power consumption by 50% compared to conventional models used for high-speed large-volume data transmission between data centers.

The FU-613REA module consists of an electro-absorption modulator laser (EML) with a central emission wavelength of 1530–1565nm coupled with a transmitter optical sub-assembly (TOSA). 

The EML-TOSA module’s newly developed EML chip achieves a low power penalty (difference in power before and after transmission) of less than 1.0dB (typical), a high extinction ratio (optical output ratio between ‘on’ and ‘off’ modes) of more than 10dB (typical), and a high mask margin (indicating the performance of the optical output waveform) of more than 20% (typical). This results in the capability for long-range transmission of data up to 40km.

Mitsubishi Electric says that the increasing use of high-speed, large-volume optical transmission devices at data centers accounts for the consumption of considerable amounts of electrical power. Power consumption for the FU-613REA of just 0.6W is about 50% less than that of Mitsubishi Electric’s current FU-612REA model. Also, EML operability at high temperatures (–5ºC to 85ºC) has allowed the thermo-electric coolers to be downsized.

The module complies with the 10Gbps miniature device multi-source agreement (XMD-MSA) on package size and electrical interface. Mitsubishi Electric has also adopted CAN-type packaging suitable for mass production, replacing box-type packaging used in conventional models.
