China's cable companies as a whole showed the phenomenon of underemployment, marketing and sales fall, "trough", a series of economic downturn, China's cable industry into an unprecedented predicament. Today, the cable companies face overcapacity competition, some enterprises in order to survive, has been considering looking for a new investment.
The current status of China's cable market is hdmi splitter sluggish. Mainly because the cable overcapacity problem. In recent years, with the rapid development of the domestic telecommunications, electricity, energy, transportation, cable manufacturers as springing in large numbers. Currently, the country's cable production companies have over 7000. On the current point of view, even if the cable is still the next 5-10 years to meet the economic development.
vga cable industry is relatively low barriers to entry, leading cable manufacturer has more and more and more, product homogeneity is more serious. Especially with the sharp rise in copper prices and a variety of raw material prices on the market, many enterprises in order to hdmi to dvi adapter reap greater benefits more choose not honest business behavior, even deliberately using inferior raw materials for production, in order to reduce costs, vga cable so necessarily a direct result of key indicators conductor resistance, the degree of crosslinking, such as not up to standard requirements. Currently, in the cable industry, a lot of product failure or shoddy products.
Overcapacity, the consequences could be disastrous. Now, more and more serious vicious competition, resulting in the entire cable industry profitability into recession. This year, the industry average profit cat5e patch panel margin has been declining, so extensive development continues, the problem is not the survival of a single enterprise, but the entire industry is facing a loss. How to solve the problem of overcapacity has only accelerate the development of the core competitiveness of the full range of high-end products through the integration of resources, survival of the fittest, the cable industry can be sustained and healthy development.

WISDOM vga cable and cable industry still wary of the drawbacks
With the introduction of five- integrated transportation system planning , the state railway construction policy warmer, promote urban rail transit construction across the news heard booming transportation construction , for cable companies is undoubtedly favorable . However, the same should also see that the cable industry development and construction of rail transit is not completely synchronized.
WISDOM vga cable users centralized monopoly WISDOM hdmi to dvi adapter enterprises decentralized , less large central enterprises , no international brands such as traditional cable market criticized in the field of rail transport cable still exists . Compared with traditional cable market , due to the metro cable , marine cable and other cables strictly retardant , halogen-free , smoke suppression requirements ; country regional differences, such as the hot and humid climate of the South and the high and low voltage power cables and more ants environment , mica insulation fireproof cable accessories , mineral insulated cable fire , leakage coaxial cable and other high-end products , our R & D capability is still less than the current low level of popularity , in part dependent on imports of high-end products .
In addition , WISDOM vga cable due to the cat5e patch panel rapid development of rail transport market , capable of producing less sophisticated end product companies , one of the few companies with limited human and financial resources, in order to meet customer demand, intense side of the purchase of equipment , additional human resources side , resulting in increased fixed costs , a shortage of liquidity , the objective follow-up research and development capabilities of the enterprise caused some impact . The small business , capital, technology, personnel are relatively weak, the product quality can not be guaranteed due to its low price , the market tends to be dominated by them . These companies did not form their own core competitiveness , it is difficult to resist the impact of the market.
Then, in the field of rail transport , the cable companies WISDOM fiber optic cable should be alert to how the drawbacks of traditional markets , namely domestic enterprises should improve their technical level, the high-end product development and foreign cable snapping ; second is to break the monopoly of the current technology , so that more enterprises to participate come ; Third, production of cable products should be in accordance with national standards.

hdmi extension cable and introduced a major role
HDMI's English name is "High Definition Multimedia", in Chinese means High Definition Multimedia Interface. HDMI interface can provide data transfer bandwidth up to 5Gbps, can transmit audio signals without compression and high-resolution video signal. At the same time WISDOM server cabinet without having to send the signal before the D / A or A / D conversion, hdmi extension cable can guarantee the highest quality audio and video signal transmission. The benefits of using HDMI is: only one HDMI cable, you can transmit audio and video signals simultaneously, unlike now need to connect multiple wires; Meanwhile, the wireless digital / analog or analog / digital converter, can achieve higher audio and video transmission quality. For consumers, HDMI technology not only provides a clear picture, and because the audio / video using the same cable, which greatly simplifies the installation of a home theater system. hdmi extension cable high-definition digital multimedia interface (High-definition Digital Multimedia Interface) HDMI 1.0 standard promulgated. On WISDOM 12 port patch panel pin HDMI and DVI compatible, but with a different package. Compared with DVI, HDMI can transmit digital audio signals, and adds support for HDCP, while providing a better DDC optional features. HDMI supports data transfer rates of 5Gbps, can transmit as far as 15 meters, sufficient to meet a 1080p video and an 8-channel audio signals. And because the audio signal needs a 1080p video and an 8-channel is less than 4GB / s, HDMI therefore WISDOM hdmi switch there is a great margin. This allows it to be connected with a DVD player, cable receiver and the PRR. Also HDMI supports EDID, DDC2B, and therefore has the HDMI device has a "plug and play" feature, automatically "consultation" between the source and display devices, automatically selects the most appropriate video / audio formats As prolong color on color No access to drawings
