There are five physical layer standards for Gigabit Ethernet using optical fiber (1000BASE-X), twisted pair cable (1000BASE-T), or shielded balanced copper cable (1000BASE-CX). Half-duplex gigabit links connected through repeater hubs were part of the IEEE specification, but the specification is not updated anymore and full-duplex operation with switches is used exclusively.ġ000BASE-T capable network interface card made by Intel, which connects to the computer via PCI-X It quickly became a built-in feature in many other computers.

In 2000, Apple's Power Mac G4 and PowerBook G4 were the first mass-produced personal computers to feature the 1000BASE-T connection. Initially, Gigabit Ethernet was deployed in high-capacity backbone network links (for instance, on a high-capacity campus network). This was part of a larger group of protocols known as Ethernet in the First Mile. IEEE 802.3ah, ratified in 2004, added two more gigabit fiber standards: 1000BASE-LX10 (which was already widely implemented as vendor-specific extension) and 1000BASE-BX10.With the ratification of 802.3ab, Gigabit Ethernet became a desktop technology as organizations could use their existing copper cabling infrastructure. IEEE 802.3ab, ratified in 1999, defines Gigabit Ethernet transmission over unshielded twisted pair (UTP) category 5, 5e or 6 cabling, and became known as 1000BASE-T.(For the history behind the "X" see Fast Ethernet § Nomenclature.) 802.3z is commonly referred to as 1000BASE-X, where -X refers to either -CX, -SX, -LX, or (non-standard) -ZX. The initial standard for Gigabit Ethernet was produced by the IEEE in June 1998 as IEEE 802.3z, and required optical fiber.Gigabit Ethernet was the next iteration, increasing the speed to 1000 Mbit/s. Fast Ethernet increased the speed from 10 to 100 megabits per second (Mbit/s). Dimensions: 77 (L) x 140 (W) x 28 (H) / 3.03 (L) x 5.51 (W) x 1.Ethernet was the result of research conducted at Xerox PARC in the early 1970s, and later evolved into a widely implemented physical and link layer protocol.Input power: IEEE 802.3af/at-compliant PSE, 30 W max., 52–55 VDC.Certifications: FCC Class A, CE, UKCA, NDAA.Two RJ45 10/100/1000 Mbps PoE output ports One RJ45 10/100/1000 Mbps input port for 48V IEEE 802.3af/at-compliant signal IEEE 802.3at (High-Power PoE+ Power over Ethernet).Fanless design ideal for silent operation.PoE-Powered 3-Port Gigabit Switch with PoE Passthrough.Compatible with IEEE 802.3at/af-compliant powered devices (PD).Compatible with IEEE 802.3at/af-compliant PoE injectors and PoE switches (PSE).Requires no additional power supply draws power directly from the PoE input.PoE awareness ensures that power is only sent to IEEE 802.3af/at-compliant devices non-PoE devices only receive data.Supports 10/100/1000 Mbps data rates and delivers up to 25 W to connected PoE devices.Saves time and money by delivering data and power via existing network cables.Doubles the connection distance between PoE source and device from 100 m (328 ft.) to 200 m (656 ft.).Connects and powers two PoE devices such as network cameras, Wireless Access Points or VoIP phones from one PoE injector or PoE switch PSE port.This product was designed to be as easy as possible to set up and use.
Simply connect the "PoE In" port with your PoE injector or PoE switch, and connect the "PoE Out" ports with the PoE devices that you wish to connect (e.g., a VoIP phone and a PoE network camera). The cable length on both ends can be up to 100 meters (328 ft.), bringing the total distance between PoE source and device to 200 m (656 ft.). The repeater forwards data at Gigabit speeds and offers up to 30 watts of input power to a connected IEEE 802.3af- or IEEE 802.3at-compliant device. The Intellinet Network Solutions 2-Port Gigabit High-Power PoE+ Extender Repeater supports the IEEE 802.3at protocol. Simply connect the PoE Extender to the LAN switch port and use the existing Cat5e/6/6a cabling to deliver DC power as well as transfer data. Reduce Wiring CostsĪvoid the expense of running AC power lines for your wireless access point, network camera or IP phone. The PoE+ extender does not need any additional power supply, as it draws the power it needs from the PoE input. The Intellinet Network Solutions 2-Port Gigabit High-Power PoE+ Extender Repeater extends connection distances from a PoE source to two output devices up to 100 m (328 ft.) via Cat5e or Cat6 cable.
