Mitsubishi Electric Launches High-Power Laser Diode for GPON Applications
Oct 25, 2006 8:00 AM
Mitsubishi Electric has completed development of the ML9xx46 series, a high-output laser diode capable of transmission rates of 2.5Gbps. The diode will be most suitable for applications such as fiber-to-the-home (FTTH)-based Gigabit Passive Optical Network (GPON) networks. Sample shipments will begin on Nov. 11, 2006.
FTTH, most widely implemented as passive optical networks (PON), will need to improve its downstream transmission speed (from access station to subscriber) to respond to increasing needs, say Mitsubishi Electric representatives. PON transmission rates are below 1.25Gbps, and many access stations are moving toward the improved GPON transmission rates of 2.5Gbps. GPON will begin serious commercialization in the United States starting in Japanese fiscal 2007.
With improvements in transmission speed, the industry has sought to secure optical input/output strength on the receive side by using higher than previous optical output on the transmitting side. According to company representatives, the ML9xx46 series can respond to increasing speed demands with one of the best optical output rates in the industry, as well as a large operating range of -40 degrees C to +85 degrees C.
