Development of 1.3 micrometer band transmitter optical sub assembly laser module by Mitsubishi
Mitsubishi Electric launched the 1.3 micrometer band transmitter optical sub assembly (TOSA) laser module targeted for 10Gbps optical transmission market. The FU-45RDF-9M2 is in compliance with three standards for optical transceivers one being the XFP, a standard for optical transceivers in unifying SONET, SDH and Ethernet, fiber channels and other data transmission standard and the other being the SFP+, also a unified standard for enhanced 8.5 and 10 Gigabit small form factor pluggable module and finally the XMD-MSA, which is a unified standard for mechanical and electrical interface of small optical devices installed in XFP. The FU-45RDF-9M2 functions at a low operating current with a wide temperature range of -20 to 95 degrees Celsius. These features are essential due to increasing demand for optical transceivers capable of operating with low power consumption and within a wider temperature range as it is difficult for equipment to release its internal heat due to high density mounting of the optical transceiver the TOSA is required to operate over a wider temperature range. The FU-45RDF-9M2 achieved this capability through utilization of a newly developed distributed feedback laser diode (DFB-LD). The newly developed FU-45RDF-9M2 operates at 25mA at 25 degrees Celsius which will contribute to overall power consumption in networks. Mitsubishi Electric has commenced shipping of FU-45RDF-9M2 as of July 1st, 2009.
