Coaxial cable model specifications and parameters

Coaxial cable model specifications and parameters Coaxial cable can be divided into two basic types, baseband coaxial cable and broadband coaxial cable. At present, the commonly used baseband cable has a shielded wire made of copper mesh and has a characteristic impedance of 50 (such as RG-8, RG-58, etc.); the shielding layer of a commonly used cable for wideband coaxial cable is usually stamped with aluminum. Into a characteristic impedance of 75 (such as RG-59, etc.).

Coaxial coaxial cable and fine coaxial cable mean whether the diameter of the coaxial cable is large or small. The thick cable is suitable for relatively large local networks. It has a long standard distance and high reliability. Because it is not necessary to cut the cable during installation, you can flexibly adjust the computer's network access position as needed. However, the thick cable network must be equipped with transceiver and transceiver cables. It is difficult to install, so the overall cost is high. On the contrary, the thin cable installation is relatively simple and the manufacturing cost is low. However, since the cable is cut during the installation process, both ends must be equipped with a basic network connector (BNC) and then be connected to both ends of the T connector. Therefore, when the connector is connected for a long time, it is likely to cause poor contact. The hidden danger is that this is one of the most common failures that occur in current running Ethernet.

In order to maintain the correct electrical characteristics of the coaxial cable, the cable shield must be grounded. At the same time, there must be terminators on both ends to weaken the signal reflection.

Whether the thin cable or the thin cable is a bus topology, that is, one cable connects multiple machines. This topology is suitable for machine-intensive environments. However, when a contact fails, the fault affects all the machines on the entire cable in series. The diagnosis and repair of faults are troublesome. Therefore, they will be gradually replaced by unshielded twisted pairs or optical cables.

HR STONE mined two kinds of Semi Precious Stones: Blue Sodalite and tiger eye. Specially sodalite mineral quarry in Africa, The sodalite rock in Africa that also contains abundant blue sodalite and white nepheline. Both of these minerals have a hardness of approximately 6 on the Mohs hardness scale.The quarry start to yield two kinds of sodalite Blue blocks, big size blocks, small size blocks in 2018. Max size of big block can be about 250*180cm and weight about 15-20 ton per block. Small block has two sizes: 3-10cm 10-30cm . Annual yield of blocks is about 100containers.Blue sodalite has two kinds of color classifications, one is blue mainly, one is blue and white mixed.According to the color purity and texture, the blocks have different ranks for your reference.

      We ship the blocks to China and produce them into finished products, such as translucent blue sodalite slabs, table and arts. Whether super blue color or blue and white mixed, you can find out the right color you favor from our blue sodalite blocks and finished product.

      We normally produce translucent blue sodalite slab with small blocks, so the blue sodalite is laminated with natural or artificial stone, glass, or Acrylic.

       If you prefer blue sodalite slab is translucent, you can chose slab laminated with glass. Translucent blue sodalite is full of  bright and fantastic colors and atmosphere.

      Blue sodalite blocks, small or big size; blue  sapphier stone slab, blue sodalite table-,welcome to contact us for details.

      sodalite vs lapis :Blue sodalite has a strong resemblance to Lapis. For metaphysical purposes, this stone is said to improve one's Logical thinking.


       Sodalite was originally discovered in Greenland in the early 1800's, then about 100 years later it was next found in Ontario. A few other sources, mostly in Africa, exist today.

  We also have other semi precious stones wholesale, such as Tiger eye rough-super yellow color and commercial rank for your choice. Tiger eye only has small blocks.
