          Polysilicon prices fell sharply and many companies stopped production

          In the recent period, the price of polysilicon has fallen like a waterfall, plummeting all the way down, from the previous high of 3.5 million yuan/ton to the average price of 200,000 yuan/ton in November of this year, with an intermediate drop of 3.3 million yuan, not only The price bubble that exists in the polysilicon industry has been broken, and the difference is only half the industry average cost of 300,000 to 400,000 yuan per ton. This fall in cost price has caused many polysilicon companies to shut down production.

          In 2003, the introduction of Germany's PV subsidy policy greatly promoted the development of the solar PV application market in Germany and Europe. The demand for solar grade polysilicon market has grown explosively and prices have risen rapidly. In 2008, the international polysilicon price reached 3.5 million yuan/ton in one stroke. For a time, the polysilicon industry has become a highly profitable industry that has attracted much attention. It has invested and built factories and increased investment to expand factories. China has also grown into one of the world's largest producers of polysilicon in the process.

          After that, the domestic polysilicon industry experienced a price drop. In the second half of 2008, due to the impact of the international financial crisis, polysilicon prices began to decline rapidly and fell to US$40/kg from 2008 to 2009, less than one-tenth of the peak period. Fortunately, after entering 2010, with the improvement of the world economic situation, the downstream photovoltaic rapidly warmed up. Polysilicon gradually recovered lost ground in the later period, and prices gradually recovered steadily, reaching a maximum of 800,000 yuan/ton.

          However, what many domestic companies did not expect was that the relative stability at the moment was not the end of the nightmare of polysilicon price decline. Instead, it was the beginning of a new round of nightmare nightmares.

          Fiber Optic Patch Panel is now widely used in networks and it is an integrated unit for fiber management, we are offering various kinds of Fiber Optic Patch Panel, such as wall mounted fiber optic patch panel, rack mounted fiber optic patch panels. These equipment functions to fix and manage the fiber optic cables inside the box as well as provide protection.
          Our wall mounted fiber patch panels accommodate up to 8 modular panels and is equipped with routing guides to limit bend radius and enhance strain-relief control. The 16-gauge steel with corrosion-resistant black powder finish coat housing provides excellent protection for the inside fibers. Wall-mount available unloaded, as well as having the capability to become a full-splice enclosure with mechanical terminations. A large variety of connector adapters are offered to meet your specific requirements. Such as SC, FC, ST, LC, etc, we can also pre-install various kinds of fiber optic pigtails inside the patch panel.

          YLTelecom offers a series of changeable inside panels to fit for different kinds of the adaptor interface, and fit for both round and ribbon fiber optic cables. Our rack mounted fiber patch panels can be drawer type or economic type without draw design.



          A Fiber-Optic Patch Panel is used to separate out the fibers within a fiber-optic cable. By using one of these panels, the fibers can be spliced to individual fibers on other cables, allowing the cables to be crossed and connected in a variety of ways. In addition, the panel creates a safe environment in which to work with exposed fibers.

          There are two main types of Fiber-Optic Enclosures. One is a wall-mounted device, which, in its most basic form, can keep 12 different fibers separate from one another. If the fiber-optic cable has more than 12 fibers, the extra fibers can be moved to a second panel or an engineer can use a panel that is designed to hold more fibers separately. Wall-mounted panels can be constructed to hold up to 144 fibers at once.

          The other type of Fiber-Optic Patch Panel is a Rack-Mounted Panel. This type of panel holds the fibers horizontally and is often designed to open like a drawer. Sliding the panel open gives an optical engineer easy access to the fibers inside.
