As this FPC is 80 percent smaller than comparable solutions the new module can be installed in SFP+ compliant transceivers while simultaneously keeping the LC receptacle package of the 10Gb/s miniature device (XMD-MSA).
By using highly-efficient distributed feedback laser diodes (DFB-LDs) for medium and long-distance transmissions and fabry-perot laser diodes (FP-LD) for short-distance communications, the new product can operate at currents of just 70mA, which is 20 percent lower than the current consumed by previous modules. This leads to a decrease in power consumption as well as to an increase in operating temperature to 90 degrees C, which is 10 °C higher than before.
With these features the new TOSA series (FU-456RDF and FU-466RLD for 10G and FU-442RDF and FU-443RLD for 8.5G transmission) from Mitsubishi Electric enables the design of small transceiver systems. These are operating with low power consumption over a wider temperature range which is essential features to achieve high-density installations in fiber based applications like metro area networks and high speed storage area networks.
