Multi-vendor installation in structured cabling system channels

Summary

As the LAN speed increases, the transmission capability of the cabling system will depend on the outstanding performance of all components in the cable and LAN channels.

End-to-End cabling system manufacturers are not manufacturers of individual components) have obvious advantages in terms of end-to-end channel performance. Obviously, in this case, the excellent design of cables, Jacks, and plugs will improve reliability and performance. The relationship between components of other cabling systems can be adjusted only after the relative advantages and disadvantages of each component in the cabling channel are carefully evaluated.

Structured Cabling Channel

The cabling implementation used to define end-to-end performance is a 4-connector or 6-connector channel. This part of the cabling system is called the level subsystem located between the floor cabling device and the work zone), and is also the most controversial area for LAN and cabling performance.

The role of multi-vendor solutions in structured connection solutions.

Each supplier designs and manufactures their respective products in different ways, sometimes in a unique way, based on factors such as patents, tools, and electrical properties being optimized. As a result, when products of different vendors are used together in the transmission channel, the optimal characteristics of a product may be adversely affected by another product with low performance. The performance of the entire system will be restricted by the worst-performing products in the transmission channel.

The advantages of the united states SYSTIMAX are first reflected in the highest system level. This is because we use it as part of an end-to-end integrated solution when designing, testing, and manufacturing all components.

It is hard to imagine what the situation is when other solution providers assemble components from different manufacturers into end-to-end channels. In this solution, signal reflection in the channel will lead to return loss, which will adversely affect the performance of the entire network. If the components do not match each other, the channel traffic at each interface is limited and the signal is weakened. This phenomenon exists in both copper and optical cable channels.

Parameters affected by multi-vendor solutions in structured cabling system channels

The data transmission capability of the structured cabling system is affected by a variety of unfavorable factors that bring the system components and their surrounding environments into the channel. The following lists some unfavorable factors that affect the throughput of structured cabling systems:

◆ External noise

◆ Latency and latency Deviation

◆ Insertion loss/Attenuation

◆ Impedance mismatch/Return Loss

◆ Crosstalk signal

These potential unfavorable factors may cause bit errors, thus reducing the total throughput of the channel in the structured cabling system.

Throughput

For end users, throughput is the most affected parameter when a multi-vendor solution is used in a channel.

Throughput can be defined as the total capacity of the cabling channel to process or transmit data within a specified period of time. The maximum throughput of a channel can only be obtained under ideal channel conditions, but cannot be obtained in real-world installation. All channels contain various unfavorable factors, resulting in the channel working below the maximum capacity or throughput. In communication systems and Specific LAN, the channel design must be able to offset these adverse factors.

All these potential unfavorable factors may cause bit errors, reducing the total throughput of the channel in the structured cabling system.

The error rate (BER) is the ratio of the number of received bits to the number of transmitted bits. In data applications, a high BER may cause a decline in network performance due to the re-transmission of signals. In video applications, a high BER may cause intermittent display, frame loss, and mosaic snow ). In various application fields, high BER will lead to unsatisfactory performance.

Wiring parameters include impedance, channel return loss, insertion loss, and crosstalk. Understanding these parameters is especially important to evaluate the full potential of the cabling system.

Insertion loss is usually expressed in dB/unit length, such as dB/1,000 feet), to measure the attenuation of signals in cable transmission. It is a key parameter that determines the available bandwidth.

External Noise

Noise enters the channel through external electromagnetic fields near the channel. Non-Direct electrostatic discharge (ESD) or fast current transient (EFT) is one of the external noise sources.

In the cabling system of the company, products with excellent balancing performance solve this noise problem. Balancing is the degree to which the signal is equal to the amplitude of each line online, but the phase of each line is opposite. Each signal is measured relative to the Earth. If the signal is used in a very balanced manner, the average voltage is zero. However, this balance may be affected. The main factor affecting the balance is the connector in the link.

When the channel is not balanced, for example, the cable shielding reduces the balance performance), there will be a voltage between the line pairs, the voltage will be added as a common mode noise to the signal of transmission, this increases the bit error rate. The system will rely on the common mode Elimination Technology (CMR) of the receiver to eliminate all impacts. In addition, imbalance increases the number of signal transmissions to reduce immunity.

In a LAN environment, balanced transmission by well-balanced electronic devices and cables will not require the use of wire shielding measures to prevent external interference and radiation, and there is no need to consider additional grounding and joining.

This is an important parameter when the channel of a structured cabling system uses a multi-vendor solution.

Latency and latency Deviation

The delay time for a signal to be transmitted from one end of the cabling channel to the other end is equal to the length of the cable divided by the propagation speed of the transmission medium. This latency is called propagation latency.

The actual cable propagation speed depends on the properties of the Insulator Material around the wire. The cable propagation delay is manifested by the worst cable pair.

The US iimax solution delivers excellent propagation latency and latency deviation margin

Insertion Loss, also known as attenuation) is the loss or attenuation of the signal transmitted in the transmission media. Loss occurs for any type of transmission media. Insertion Loss significantly affects the maximum distance between two devices.

Impedance mismatch/ripple loss

The Characteristic Impedance corresponds to the input impedance of an infinite length even transmission line.

The impedance of a cable varies with its length. This fluctuation of impedance will also lead to reflection.

Channel return loss (RL) is a measure of impedance consistency along cables, connectors, and jumpers. The factors that affect the channel uniformity include the average distance between two wires in a wire pair, the winding uniformity of the wire pair, and the cross-sectional uniformity in the insulation layer. These parameters are important measures to measure the manufacturing quality of cables, connectors, and jumpers. Even if there are small changes, they will significantly reduce RL performance.

It is especially important to try to reduce the impedance mismatch in the channel when using mixed functions in the interface circuit, such as 1000BASE-TX or 10GBASE-T.

Channels composed of different or unmatched impedance cables and connectors will have poor ripple loss which is caused by all reflection generated during connection ).

Crosstalk signal

Crosstalk signals are probably the most important feature of high-speed data application wiring.

It is the irrelevant energy in a signal line caused by interference from other signal lines. Adjacent lines may cause too many incoming signals to damage data and cause errors.
