-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

Abstract:Download cables are widely used in the design and debugging of electronic systems. 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
Looking forward to, looking forward to, the new computer MacBook came, but the thin Mac does not have a network interface, and the school campus network wireless speed is very slow, how to do?Had to buy an external USB adapter (I would say that the MacBook built-in lightning adapter is too expensive?) ), the hardships received goods, plug in the network cable ... The results show: "USB 10/100 LAN" has a self-assigned IP address and will not be able to

Set up the router, I believe everyone will, but the wireless router with a wireless router, there are several methods, I think the most useful, the most easy to operate practical methods have 2 kinds to everyone said:
Method One: It is very simple to use a network cable to boot from the first router to any port on the second router's LAN, and remember that you cannot plug into the WAN port. This method is generally used by more people, basically no t

CATV Network is an efficient and inexpensive comprehensive network, it has a wide bandwidth, large capacity, multi-function, low cost, anti-interference ability, support a variety of services to connect the advantages of millions of households, its development for the development of Information superhighway laid a foundation. In recent years in China CATV Network development, the country has built more than 1500 cable TV stations, the number of users

Some people often ask me some questions about the network cable. When I talk with them, I find that the network cable errors are extremely common. The root cause is that the line makers do not understand the principle, so I think it is necessary to write something to talk about.First, let's talk about differential transmission. The so-called differential transmission means that the sending end transmits an
Now, Gigabit Networks are becoming more popular, but the practice of Gigabit Networks is not widely understood by many friends. Hope to help you.
The gigabit 5 category or over 5 category twisted pair wires are in the same form as the 10-Gigabit network cable. They are also divided into two types: pass-through and crossover. The straight-through network cable is exactly the same as what we usually use. How
The on-site test of optical cable construction is very important. It is used to prepare for the overall commissioning of the optical terminal. The optical fiber test items in the optical fiber have the measurement of transmission attenuation. for Multimode Optical Fiber, test the baseband response when necessary.
The purpose of the single-disk optical cable test is to ensure the quality of the factory produ

1. Introduction to return loss indicators
Ripple loss is an important indicator of digital cable products. Ripple loss combines two kinds of reflection effects, including the deviation of nominal impedance such as 100 Ω and the influence of structure, used to characterize the performance of a link or channel. It is caused by the non-uniformity of the characteristic impedance of the cable length. It is caus
Rats are widely used in various regions of the world as a type of rodents with strong fertility and vitality. Because of their well-developed and constantly growing population, as a result, rats have the habit of keeping their teeth sharp by biting objects. The unique smell of plastic makes plastic a common biting object.
Whether it's in the wild or in the human activity area, the mouse has a strong damage to the wire/cable jacket or insulation layer.
Ribbon cable
A fiber optic cable that is machined by a plurality of single fiber fibers, which are colored, stacked into strips, and two times molded. There are two kinds of optical fiber, namely the encapsulation type and the side-viscosity type, the former can withstand transverse pressure, the latter thickness is thin. Each band can have 4, 8, 12 or 16 fiber. In-band fiber spacing is 0. 28mm (for 4, 8)
Culvert cables are not easy to bury and difficult to maintain. The problem can be solved by adopting the steel pipe protection and the reverse buckle of the cable trough.
Signals and cables pass through the culvert and cannot be dug deep and buried as usual. Therefore, the cables are exposed, which facilitates protection, but cannot receive good results. The cable trough and the cover plate are used to pro

My colleagues reported that the Local Area Network could not be mounted. After reading the past, they found that the prompt "the network cable is not plugged in". I suspect that it is not plugged in, plug in, restart, and reinstall the NIC Driver.
My colleague reported that the network cable could be connected to the LAN using a laptop. After
verify the connectivity between each pin end and end of the cable link and check the winding problem. Any wrong wiring format, such as open circuit, short circuit, cross-connection, reverse connection, and string winding, should be able to be detected.
Attenuation is another important parameter for determining the performance of the cabling system. Any electronic signal from the signal source will cause energy loss during transmission, which is no ex
