1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) or Category 6 cable should be used. The Category 5e specification includes test parameters that are only recommendations for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3ab standards.

Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”

Note that when testing your cable installation, be sure to include all patch cables between switches and end devices.

Adjusting Existing Category 5 Cabling to Run 1000BASE-T

If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T, there are basically three measures that can be applied to try and correct the problem:

1.Replace any Category 5 patch cables with high-performance Category 5e or Category 6 cables.

2.Reduce the number of connectors used in the link.

3.Reconnect some of the connectors in the link.

Fiber Standards

The current TIA (Telecommunications Industry Association) 568-A specification on optical fiber cabling consists of one recognized cable type for horizontal subsystems and two cable types for backbone subsystems.

Horizontal 62.5/125 micron multimode (two fibers per outlet).

Backbone 62.5/125 micron multimode or singlemode.

TIA 568-B will allow the use of 50/125 micron multimode optical fiber in both the horizontal and backbone in addition to the types listed above. All optical fiber components and installation practices must meet applicable building and safety codes.

ES3628EA specifications

Accton Technology's ES3628EA is an advanced network switch designed to meet the growing demands of modern enterprise environments. This managed switch is engineered to provide a robust solution for delivering high-speed connectivity and reliable performance across local area networks (LANs). The ES3628EA features a 28-port configuration, combining 24 Gigabit Ethernet ports and 4 SFP (Small Form-factor Pluggable) uplink slots, allowing for flexible network design and scalability.

One of the standout characteristics of the ES3628EA is its support for Layer 2 and Layer 3 functionalities, offering network administrators enhanced control and management over data traffic. With features such as VLAN (Virtual Local Area Network) support, the switch enables efficient segmentation of networks for improved security and performance. VLAN tagging allows for the separation of different data types on the same physical infrastructure, reducing broadcast traffic and enhancing overall efficiency.

Additionally, the ES3628EA supports advanced Quality of Service (QoS) mechanisms, which prioritize critical network traffic, ensuring optimal performance for applications like voice over IP (VoIP) and video streaming. The ability to configure multiple queues allows administrators to define traffic patterns, allocate bandwidth effectively, and minimize latency.

The device also incorporates comprehensive security features, including port security, access control lists (ACLs), and support for802.1x authentication. These capabilities help safeguard sensitive data and restrict unauthorized access to the network.

Power over Ethernet (PoE) support is another significant feature of the ES3628EA. This technology allows the switch to deliver power alongside data over Ethernet cables, facilitating the connection and powering of devices like IP cameras, VoIP phones, and wireless access points, all without the need for additional power sources.

Furthermore, the ES3628EA boasts a user-friendly web-based interface for configuration and management, making it accessible for network administrators of varying expertise. In addition to the web interface, it also supports SNMP (Simple Network Management Protocol) for more advanced network monitoring and control.

Designed for reliability and performance, the Accton Technology ES3628EA is a versatile solution that integrates seamlessly into diverse networking environments, delivering the capabilities required for today’s demanding applications. Its blend of speed, security, and advanced management functionalities makes it an excellent choice for enterprises looking to enhance their network infrastructure.
