Transform RJ-45 for tomorrow's networks (1)

When it comes to Ethernet interfaces, it will always remind you of Coupled modular RJ plug and Jack connector. Since the concept of structured Telecom cabling, such interfaces have dominated the telecom market. Previously, from the late 1960s s, almost every sold phone headset had such two pair of connectors. There is no doubt that RJ plug and socket interfaces are widely used. However, as the data transmission speed approaches 10 Gb/s, they seem to be insufficient. Moreover, most manufacturers do not realize that this is an opportunity for innovation, but are keen to rely on outdated compensation circuits to fine tune and refine the outdated housing and contact Design of existing modular sockets, to overcome the inherent high-frequency electrical and mechanical defects of the RJ modular Plug Connector.

As a revolutionary measure, Simon has completely changed the internal functions of the RJ modular plug and socket. The patented new technology fundamentally eliminates the differences between plug and outlet connections, optimizes coupling performance, and specifies the use of a complete targeted correction and compensation circuit, the connection device has unprecedented Transmission Performance margin and mechanical reliability. These revolutionary enhancements incorporate Simon's brand new Z-MAX series extension Category 6 6A) connection hardware and wiring solutions.

Better connector design

Today's RJ modular connectors are required to work and provide performance margin under unforeseen conditions five years ago. In particular, this interface needs to show ultra-low horizontal internal line-to-room and external) crosstalk at a maximum of 500 MHz frequency, supporting up to 600mA of the current per line in the PoE Plus application, maintain reliable and robust connections in various environmental conditions, while also using environmentally friendly materials. In the face of the challenge of designing a next-generation extension six-class connector that surpasses these requirements, Simon's engineers believe that a thorough transformation should be made to the RJ modular plug and socket.

Simon has identified the following key points for improving the design:

Electrical:

1. Eliminate high variability related to the on-site and factory connection processes in normal conditions

2. Ensure that the performance of the modular plug is always within the "best point" of the modular socket to provide the best coupling Performance

3. Locate the Cable End to get rid of the line pair separation and line pair crossover

4. Precise Finite Element transmission model technology is used to optimize the amplitude and phase of each point between the input and output cables.

5. Electrical Isolation distribution frame and adjacent connectors on the panel to minimize external crosstalk and eliminate possible shielded connections between channels

Machinery:

1. Optimized contact shape and configuration to minimize transmission length and interruption in all components and to maximize the distance between pins of adjacent sockets to improve external Crosstalk

Performance

2. Eliminate environmentally friendly production materials, such as be and lead

3. reduces contact insertion stress and minimizes Normal Stress Changes in the plug/outlet Interface

4. Ensure that the contact shape of "first touch"/"then disconnected" can provide an independent Arc area and is completely isolated from the coupling interface area on the connector and outlet contact,

Optimal reliability for simultaneous power and Data Transmission

5. There is a modular socket Core Component suitable for all requirements of copper cabling connections, such as integrated flat/diagonal ports, or Keystone and full color jumpers)

Electrical Enhancement

Eliminate the variability of RJ-45 modular plug

Twisted Pair wires rely on precise line ry to ensure correct transmission performance. According to its characteristics, the plug-in connection process from the cable to the module will damage the geometric structure of the line pair and bring great variability to the final plug component. In addition, the four-line connection Diagram for T568A and T568B for data transmission is defined, the wires connected to Pin 3 and 6 are untwisted and separated from the wires mounted to pin 4 and 5 ). This common installation method is a major source of Crosstalk in modular plug. Line pairs connected to Pin 3 and 6 are usually called "separation line pairs ".

In addition, the line orientation is clockwise or counterclockwise based on the different ends of the end cable. This fact is often ignored. To adapt to the "image" line direction, a different line pair needs to be crossed at both ends of the cable to achieve the polarity of the pin/line pair connection. Therefore, it is impossible to use the same plug design to achieve performance consistency between the ends of the cable.

Some people refer to the modular plug-end connection process as an art. Perhaps this is because the process depends on the operator's technology. when preparing a line pair for the end connection, the operator can minimize the interference caused by the twisted pair and the line pair. It takes a long time for the training operator to correctly connect to the modular jumper. Even so, the finished patch cord must undergo a 100% transmission test to ensure correct production. After realizing that the transmission performance depends on the quality and stability of the plug-end, cabling manufacturers no longer provide assurance for field jumper production with performance levels of cat5e or higher. Performance cannot be guaranteed if there is no strict process control during production and testing.

This is a central focus in Z-MAX design because the modular plug is so critical to coupling performance with the end of the cable. Simon's engineers have thoroughly transformed the existing modular plug technology and designed the Z-MAX plug with the following features:

1. backward compatible and can be used with any manufacturer's outlet that meets the requirements of TIA and IEC.

2. This eliminates the Variability Related to the untwisted pair and the "separation line pair ".

3. This eliminates the variability caused by different color sequence on both ends of the cable.

4. fully complies with industry standards and always complies with performance ranges specified by TIA and ISO/IEC to provide maximum matching performance while maintaining

Fully compatible

To achieve these goals, Simon strategically adopted patented printed circuit board technology in Z-MAX modular plug ). In order to eliminate the Variability Related to the conventional plug-in end-to-end connection process, different printed circuit boards (PCB) are used to design cables at both ends of the cables and match the cables in color order. This design optimizes performance and keeps four complete wire pairs extending to the end point without unlocking the wire pair or overlapping one wire pair on the other. Each patch cord is connected with two different connectors. These two connectors have different circuit designs and connection schemes, specifically designed to provide stable performance and ensure full compatibility and interoperability with all modular sockets compliant with TIA and IEC requirements.
