TO-Flix is an 850-nm, optical front-end chipset for 10 Gbit/s optical transceivers, such as XENPAK, X2, XPAK, and XFP. It is designed for very-short-reach 10-Gigabit Ethernet and Fibre Channel links in enterprise, storage area networks and local area networks. It consists of an optical receiver with a PIN photodetector and a transimpedance amplifier that convert 850-nm signals to electrical data, as well as an 850-nm VCSEL. It uses flex board interconnection, and can be used with a limiting amplifier and a laser driver amplifier.
