HFRD-02.0: 2.5Gbps Small Form Factor (SFF) Transmitter
Abstract: High Frequency Reference Design (HFRD) 2.0 is a complete transmitter that is compliant with the Small Form Factor (SFF) Multisource Agreement (MSA). Data rates up to 2.5Gbps are attainable with the high-speed Fabry-Perot laser and the MAX3863 high-speed direct modulation laser driver. Average power and extinction ratio are held constant over the full -40°C to +85°C temperature range using the Dallas Semiconductor DS1847 dual temperature-controlled digital resistor, that can be programmed using an industry standard 2-wire interface. Gerber files and schematics may be provided, however reference design boards are no longer available.
