Marvell's Media Detect Feature And Finisar's GBIC Modules Address Gigabit Media Selection.Marvell and Finisar Corp. announced they have teamed up to offer the industry's first Gigabit solutions to provide end-users with complete flexibility in copper and fiber media selection. These two solutions consist of Marvell's Alaska Ultra+ PHY See physical layer and physical. transceiver, offering an integrated circuit integrated circuit (IC), electronic circuit built on a semiconductor substrate, usually one of single-crystal silicon. The circuit, often called a chip, is packaged in a hermetically sealed case or a nonhermetic plastic capsule, with leads extending from it for (IC) solution, and Finisar's family of Gigabit Interface Converters
Marvell's Alaska Ultra+ transceiver offers simultaneous support of both copper and fiber interfaces, whereby the copper port is connected to a transformer and RJ45 connector, and the fiber port is connected to a Gigabit fiber-optic module or GBIC (GigaBit Interface Converter) A hardware module used to attach network devices to fiber-based transmission systems such as Fibre Channel and Gigabit Ethernet. The GBIC converts the serial electrical signals to serial optical signals and vice versa. device. The device's Media Detect feature automatically senses whether the end-user has inserted a CAT 5 copper or fiber-optic cable, performs Auto-Negotiation, and provides seamless "plug and play" configuration. Working in collaboration with Marvell, Finisar already offers an alternative approach to Gigabit media independence. Based on Marvell's Alaska Gigabit Ethernet An Ethernet standard that transmits at 1 Gbps. Used mostly to connect high-end workstations and servers as well as for network backbones, Gigabit Ethernet transmits full duplex from point to point using switches and half duplex in a shared environment (CSMA/CD) using a hub. PHY, the Finisar FCM-8519-3 offers GBIC support for 1000BASE-T on CAT 5 UTP UTP (uridine triphosphate): see uracil. (Unshielded Twisted Pair) See twisted pair. UTP - unshielded twisted pair copper media. In conjunction with Finisar's complete line of fiber-optic GBIC products, it provides significant benefit to the customer base by offering fiber or copper Gigabit connections interchangeably. Marvell's Alaska Ultra+ Gigabit Ethernet over copper transceiver samples (88E1011S) are currently available while the Finisar FCM-8519-3 1000BASE-T GBIC module is currently in volume production. |
