Aim of Sale
FTTH, most widely used as Passive Optical Networks (PON), will need to improve its downstream transmission speed (from access station to subscriber) to respond to continuing increasing needs. PON transmission rates are below 1.25 Gbps, and many access stations are moving towards the improved GPON transmission rates of 2.5 Gbps. GPON will begin serious commercialization in the U.S. starting in Japanese fiscal 2007.
With improvements in transmission speed, the industry has sought to secure optical input/output strength on the receiving side by using higher than previous optical output on the transmitting side. 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 --40c - +85c.
Features
1) High optical output for high speed FTTH
Laser diodes have been limited to an optical output of 10 mW since response speed diminishes with optical output at high temperatures. By optimizing the construction of the active layer where the laser diode emits light, the ML9xx46 series has improved optical conversion efficiency at high temperatures with an optical output of 15 mW and a operating range of --40c - +85c, one of the best in the industry. We've also improved modulation bandwidth by reducing capacitance of the laser diode. An 15mW optical output with an excellent response time of 2.5 Gbps will increase speeds of FTTH.
2) Reduced power consumption of transmitter using high coupling efficiency lens
Using an aspherical lens increases coupling efficiency (efficiency of light entering optic fiber from the laser), with a 70% coupling efficiency2 in the ML920T46S model. This reduces operating current, which leads to reduced power consumption in the transmitter.
