The development of the Internet has made people's understanding of the network deeper and wider. At present, all kinds of electronic products are seeking an informational road. Then the way the product is connected is inevitably used in the five types of lines that are widely used in computer networks. In the AV network cabling, it seems to be gradually becoming a trend. We can see that various audio and video products are developing in this direction. From intelligent projectors to digital conferencing systems, central control systems, matrices and switchers, the five-category network is the new product development direction. The series of questions that have arisen have been discussed among dealers for a long time. Below, we take the conference system as an example to see a few questions:
1. Is it possible to use a connection method to distinguish between all-digital conference systems ? Is the Category 5 cable connection an all-digital system? The original professional cable connection is the analog system?
2. What are the advantages of the five types of lines?
3. Has the professional cable that has been used for many years been introduced to the market?
First of all, whether it is a Category 5 cable connection or an original professional cable connection, it is just a connection method. Both can transmit digital signals. Therefore, we can't use the connection method to judge whether it is a digital conference system or a simulation conference system .
The five-category line connection method is widely used, and it is understandable that it has its advantages.
Category 5, also known as twisted pair, is the most common transmission medium available today. It consists of two mutually insulated copper wires, typically 1 mm in diameter. The two wires are twisted together to prevent their electromagnetic induction from generating interference signals in adjacent pairs. Current twisted pair cables typically include four twisted pairs. Twisted pair cables can be classified into shielded twisted pair (STP) and unshielded twisted pair (UTP) depending on whether they are shielded with a metal mesh sleeve. Generally, the computer local network only uses unshielded twisted pair (UTP). If the amount of data is large, it is best to use shielded twisted pair (STP). The network Category 5 connector is typically an RJ-45 crystal head; the maximum effective transmission distance is 100m from the hub. If you want to increase the transmission distance, you can install a repeater between the two twisted pairs, and you can install up to 4 repeaters. If you install 4 repeaters to connect 5 network segments, the maximum transmission distance can reach 500m. The Category 5 line frequency bandwidth is 100 MHz. The frequency bandwidth (MHz) is different from the transmission rate (Mbps) of the data transmitted by the cable. Mbps measures the number of bits transmitted by the line per unit time, and MHz measures the number of oscillations of the electrical signal in the line per unit time. Twisted pair cable is applied to MSCSA/CD (Carrier Sense Multiple Access/Collision Detection) technology, namely 10BASE-T (10Mbps) and 100BASE-T (100Mbps) Ethernet (Ethernet). in.
The Category 5 line has not yet been adopted by all conference system manufacturers (including some internationally renowned brands), and there are some shortcomings in its application in this regard.
It is well known that the transmission of current in computer Ethernet is very weak, mostly data traffic. According to IEEE 802.3af, power is transmitted through Ethernet, and the power transmitted to each node is limited to 350 mA. Currently, the conference systems on the market are passive, and the supply of power and the transmission of data are transmitted in one cable. The power of the conference system is generally 100W-200W, and the power supply voltage is 24V-48V. Then the transmission current is about 2A-8A. Far greater than the IEEE802.3af regulations. Therefore, this is a security risk. In particular, the RJ45 crystal head is used as a connector for the five types of wires, and the contact between them is very weak, and a large current is liable to cause damage to the connector.
On the connection, the key consideration is the firm reliability of the cable. The RJ45 crystal head is connected to the RJ45 module on the conference unit only by the small pin on the RJ45 port. People who use computer networks are very aware that such a connection is very weak, but on the computer network, a little loose or temporary fall off is harmless. However, it is not acceptable in the conference system . In the connection of the "hand in hand" microphone unit, such looseness and shedding may cause all the units after the loose or falling point to fail. The voting system is more serious and needs to be stronger, safer and more reliable.
Based on the above two shortcomings, some conference system vendors still use dedicated cables. In terms of the price and use of cables, special cables are not comparable to Category 5 lines, but the dedicated cables have been used by various manufacturers according to the standards of all levels, and of course have their superior side. For example, Philips' "6P dedicated cable", Taipower's "8PIN dedicated cable", and Bella's "8PIN dedicated cable". The dedicated cable is not worse than the Category 5 line at the transmission rate and transmission frequency. All dedicated cables on the shield are shielded and there are no unshielded cables. This kind of special cable is absolutely safe and reliable in transmitting power. After testing, it can even resist the strong current of 10A.
In the connection of cables, various professional manufacturers use professional buckles to strengthen their own cable connections, and strive to do all the work in safety, stability and reliability.
Therefore, the application of Category 5 and dedicated cables in the field of conference systems still has its own advantages. We can't arbitrarily determine whether the conference system is advanced by using a five-category connection.
