Accton’s Smart Extender (The Fast SwitcHub-2s)

Accton’s Smart Extender can boost network bandwidth fourfold, depending on your configuration (i.e., if running at 100Mbps and full-duplex operation for both ports). It provides two 10/100 Mbps RJ-45 ports (set at full or half-duplex) to connect to either a subnetwork, or directly to a server or key workstation. In addition to partitioning an overloaded network, it provides connection between legacy 10BASE-T networks and the newer generation 100BASE-TX, and can be configured to operate in either full-duplex or half-duplex data transfer mode to support the interconnection requirements of other high-speed devices.

This switching hub performs "on-the-fly" cut-through switching, which sends a packet to the other port according to the destination address scanned from the packet header. This technique reduces the latency of packet transmission to 20 microseconds or less. Compared to approximately 800 microseconds for a bridge or 1800 microseconds for a router, both of which have to store the entire packet before the it can be forwarded, the SwitcHub can deliver a quantum improvement in your network’s performance.

As a device functioning on the media access control (MAC) layer, the SwitcHub is protocol independent, and therefore compatible with IEEE802.3, IEEE802.3u, TCP/IP, NetWare, DECnet and XNS protocols. Accton’s Smart Extender can be configured as a 2-port bridge for a 10BASE-T environment; it can provide a connection between conventional 10BASE-T and high-speed 100BASE-TX networks; or can serve as a 2-port bridge in a 100BASE-TX environment. Moreover, where traditional 100BASE-TX networks restrict the maximum distance between end-nodes to 205 meters, the Smart Extender breaks down this barrier. By breaking your network into smaller and more manageable segments, each linked to the larger network with a switch, the maximum distance for communications between end-nodes is unlimited.

10BASE-T, 100BASE-TX specifications

Accton Technology is a prominent player in the networking industry, particularly known for its contributions to Ethernet technology. Among its notable products are the 100BASE-TX and 10BASE-T Ethernet standards, which have been instrumental in shaping local area networking (LAN) infrastructures.

The 100BASE-TX standard, also known as Fast Ethernet, provides a data transfer rate of up to 100 Mbps and operates over twisted-pair cabling, specifically Category 5 cables. This technology was designed to enhance the speed of traditional Ethernet (10BASE-T), which operates at 10 Mbps. The 100BASE-TX standard employs a signaling method called four-pair twisted copper cabling, which optimizes signal integrity and reduces electromagnetic interference. One of its core features is the ability to leverage existing cabling infrastructure while providing significant speed improvements, making it a cost-effective solution for upgrading network performance.

On the other hand, 10BASE-T represents the original Ethernet technology, defining a standard for 10 Mbps data transmission. It utilizes twisted-pair wiring and is capable of operating over distances of up to 100 meters. This protocol laid the groundwork for networking, allowing the widespread adoption of Ethernet in office environments and beyond. 10BASE-T employs baseband signaling, which means that the cabling is dedicated solely to Ethernet traffic, minimizing interference from other signals.

Key characteristics of both 100BASE-TX and 10BASE-T include their ability to support full-duplex communication, which allows data to be transmitted and received simultaneously, thereby doubling the potential throughput. This feature is particularly beneficial for applications that require high data rates and low latency, such as voice over IP (VoIP) and video conferencing.

Moreover, these Ethernet standards are built around plug-and-play capabilities, making network setups simpler and more accessible, even for organizations without extensive IT resources. Accton Technology supports these protocols with a range of switches and network interface cards that enable seamless integration into existing networks.

In conclusion, Accton Technology's 100BASE-TX and 10BASE-T standards are vital components in the evolution of Ethernet networking. With their impressive data transfer rates, compatibility with existing cabling, and support for full-duplex communication, they continue to be relevant in modern networking solutions, providing businesses with reliable and efficient means for data transmission.
