New iphone or supply problems due to OLED screen
Release date: 2017-09-11 Source: China Network Finance Sharing: 
The news that Apple's new products will be released on September 12th in the US time has been overwhelming, and the fastest sales will begin on September 22. According to the Hong Kong Economic Times report, Apple's new machine uses an OLED screen, but I heard that some problems have arisen in the production process, resulting in insufficient supply. At the same time, the Wall Street Journal also released similar news, due to insufficient supply caused by these problems, will delay delivery for one month, may affect the initial sales.
According to reports, in the relatively short time from the release date, Apple decided to abandon the fingerprint authentication Touch ID technology on the new iPhone. The reason is that because of the dissatisfaction with the design effect and the OLED screen production problem, Apple had to give up the Touch ID and instead use the face recognition technology to unlock it.
Investment company Sanford Bernstein analyst Sakonagi believes that if Apple can't offer consumers the new iphone8 in the most critical holiday shopping season, its iphone sales will decline.
Affected by this news, the Hong Kong stocks Apple concept sector, which was recently speculated by Apple's new products, has suffered setbacks. In the previous period, Qiu Ti Technology, which was highly sought after by funds, fell 9.78% on the 8th, audio equipment supplier AAC Technologies fell 1.09%, lens maker Sunny Optical Technology fell 2.7%, Gaowei Electronics fell 0.22%, and Tongda Group fell 2.53%. BYD Electronics fell 0.94% and Fuzhikang Group fell 1.53%. Market analysts said that the concept of Apple has risen strongly before. At present, it is affected by the geopolitical crisis to upgrade funds to hedge and profit-taking. In addition, according to the previous trend, the concept of Apple tends to be adjusted after the release of new products, coupled with the uncertainty of the current overall sales impact, it is expected that Apple concept stocks will be under pressure in the near future.

The cat7 Lan Cable are an eight-core Shield wire. Each pair has a Shield layer (commonly called a Foil Shield), and then a Shield layer (commonly called a Braided screen Shield) outside the eight cores, with the same connection as the RJ-45.The highest transmission frequency of the CAT7 Ethernet Cable S/FTP is 600MHz, and the transmission frequency of the CAT7 Network Cable is 1000MHz.
There are a number of significant differences between the six and seven cabling systems, the most obvious of which is bandwidth.The CAT6 cable of channels provide a comprehensive attenuation to crosspoint ratio of at least 200MHZ and an overall bandwidth of 250MHZ. CAT7 of systems can provide at least 500MHZ of comprehensive attenuation to crosspoking ratio and 600MHZ of overall bandwidth.
The proliferation of broadband applications has created a need for more bandwidth.For example, a typical CAT7 channel can provide a bandwidth of 862MHZ for the transmission of video signals, analog audio signals on another pair, and high-speed LAN information on a third or fourth pair.
Another difference between the CAT6 patch cable and cat7 patch cable systems is their structure.The six types of wiring systems can use either UTP or STP.The seven types of systems are based only on shielded cables.In the cat7 network cables, each pair has a shield layer, and four pairs of wires together have a common shield layer.In terms of physical structure, the additional shielding layer makes the CAT7 Ethernet Cable have a larger diameter.
Another important difference is its ability to connect hardware. The parameters of the cat7 patch cable of systems require that all pairs of wires provide at least 60DB of integrated proximal winding at 600MHZ.The cat6 systems only require 43dB at 100MHZ and 46dB at 250MHZ for the cat6 patch cable.
