Sea freight calculation methodForeign trade sea freight generally has two ways: the first full container sea freight calculation, full container sea freight = basic sea freight + sea freight surcharge;

The transmission rate of the Category 6 cabling system can provide high-speed bandwidth about three times higher than that of the Category 5e cable, and the ACR value is 300% higher than that of the Category 5e cable at 100MHz. In terms of construction and installation, Category 6 is much more diffi

As the value of PDUs is gradually enlarged and widely recognized, from national data centers to small and medium-sized users of a single cabinet, the choice and demand for PDUs are also different, especially small and medium-sized computer room users, a large group base, more risks and hidden danger

The small residual length of the communication fiber is the key to process control in the production process of the plastic coating process. The so-called residual length is: the difference between the optical fiber length and the loose sleeve length and the fraction of the loose sleeve length: As

Steel StrandA steel product called steel strands is created by twisting lots of steel wires together. Galvanized, zinc-aluminum alloy, aluminum, copper, epoxy resin, and other coatings can be put to the surface of carbon steel as needed. According to the number of steel wires

1、From the design point of view Comprehensive wiring has a point requirement if you have noticed, that is, the information point requires data, voice points can be interchanged when necessary

Fiber optic network speed is indeed fast, long-distance transmission, can achieve the real one gigabit network speed. So, in our home LAN, between the computer and the router, why not use optical fiber to connect? Well, some people compare optical fiber to a highway, the home LAN to a small village,

In the modern communication industry, communications, optical fiber transmission technology as a kind of common information data transmission mode, since it has advantages of high efficiency and high transmission speed, communication quality, greatly satisfy the demand of modern social development,

In the long-term transmission line operation and maintenance process, the heat of the line clip is the main defect of the line. Transmission line clamps are mainly equipment clamps, tension-resistant clamps, and trench clamps, etc. The following is based on the field operation and maintenance, for t

The difference between optical cable fittings and electric power fittings:Power fittings is a kind of metal fittings that connects and combines all kinds of fittings in power system.Optical cable hardware is the overhead cable used in the field of optical cable hardware, as well as direct contact op
