® Gigabit Ethernet Transceivers. Our Alaska® family of Gigabit Ethernet transceivers are designed to be solutions for enterprise networking systems where high performance and low power dissipation are absolutely necessary. Each product contains built-in 1.25 Gigabit SERDES function, which allows the device to work seamlessly over either copper or fiber-optic cabling. The devices also support value-added features such as VCT technology, which is used to diagnose the attached cable plant. This technology can allow end-users to quickly and remotely analyze the quality and attributes of the cable, thereby avoiding unnecessary equipment returns and on-site service calls. The advanced built-in diagnostics help pinpoint the cause of network malfunctions without deploying field support personnel or bringing down the network, which can significantly reduce installation time and cable debug efforts and requirements. The design for these products incorporates sophisticated digital signal processing algorithms and power management techniques to achieve low power dissipation. Target applications include Network Interface Cards, LOMs, routers and next-generation switches.
