-tube unit A micro-tube unit is composed of a silicon core layer added to the inner wall of HDPE material. Generally, the inner wall with a diameter of more than 5mm has a flow channel, the inner wall of the microtube diameter below 5mm does not have a flow channel. At present, the external diameter of the micro-tube generally ranges from 3mm to 16mm. The number of fiber cores that can be accommodated in one microtube ranges from 1 core to 288 cores or even higher. When the optical fiber single

the first time he came, he could use the cable jack, presumably I have a signal here. The last session of the affirmation has been passed, always do not go and later also sealed off. While there are days bedroom no one, I put that laptop cable to my side a try, sure enough there is a signal! Suddenly came to the spirit, feel a hope! Perhaps you will say, it is impossible to connect the network

This article introduces its basic principles and programming control methods. For the list instances of the current single-chip microcomputer's ISP serial programming mode, it briefly introduces the serial programming method and part of the protocol of at89s5x, using VC programming, the application download

Terrible! Hackers can also steal your data by disconnecting the network cable. Once a computer is infected with viruses or Trojans, most people first think of "disconnecting the network cable first" to avoid the theft of confidential data through the Internet channel. However, according to research by security experts, even if the network cable is disconnected

When connecting an IEEE 802.3af-compliant or Cisco pre-standard power-on device to an PoE line card, PoE is in standard 100 unshielded twisted pair wires (UTP) up to 5th meters) -48 VDC power supply is provided on the cable. IP phones, wireless base stations, cameras, and other IEEE-compliant port connection devices do not require Wall power supplies and can use power supplies from Cisco Catalyst

Communication Media is a physical media used to transmit information. Different communication media have different attributes and should be used for different purposes in different occasions to exert the best efficiency of different communication media. Twisted pair cables (twisted pair cables) are a transmission medium formed by encapsulating one or more twisted pair cables in an Insulating Coat. They are currently the most commonly used cabling materials in local area networks. In order to re

Feng Qiang/Wen When I got to work early this morning, I found that MSN could not log on. Many of our work contacts are currently carried out through MSN. At this time, I suddenly found that QQ (actually used TM) is still a bit useful. After all, we still have a working group. At first, I thought it was just a problem with our company's online MSN. As a result, when I asked in the group, the whole country would not be able to get on. At that time, I felt that the Microsoft MSN server was hack
