Apple needs to overcome the technical bottleneck to avoid chicken ribs

Apple needs to overcome technical bottlenecks According to foreign media reports, Apple's share price has recently encountered unprecedented difficulties after Wall Street's miracle. The company's share price has fallen to the lowest point in the past 11 months. The author believes that although people in the market generally believe that Apple's stock price is significantly underestimated, and other surveys show that about 90% of stock brokers recommend that investors continue to hold or even buy Apple stocks, but if Apple does not break it soon The bottleneck of technology strategy, Apple's stock will eventually fall into the eyes of investors as "tasteless."

Ryan Detrick, a senior analyst at Schaeffer's Investment Research, said in an interview that it is difficult for investors to find the right time to buy Apple's stock. Some analysts pointed out that the mid-term development trend of Apple's stock has begun to decline.

Apple will announce the storage of property in the fourth quarter of 2012 on the 23rd local time. Affected by Apple's previous efforts to reduce the purchase of iPad and iPhone screens, investors have expressed concern about the contents of the financial report. According to statistics, sales of the iPad and iPhone contributed to Apple’s revenue of up to 70%.

If Apple's 2012 Q4 financial report can largely surpass market expectations, then in the short term Apple needs to spend a lot of energy to restore market confidence. Some analysts believe that if Apple's financial results are just in line with analysts' estimates, there is still the possibility that Apple's stock may continue to fall in the near future. In the past decade or so, Apple’s financial report data failed to meet analysts’ prediction criteria four times, and two of these have occurred in the near future.

Chris Bertelsen, chief investment officer of Global Financial Private Capital, a Florida-based investment company, said in an interview: “Apple’s financial report must exceed 10% to more than 15% of the analyst’s expected results. Investors believe that Apple has truly achieved the return of the king." Global Financial Private Capital's assets under management are as high as $1.7 billion.

The fourth quarter of 2012 was the peak period of global consumer electronics sales, and Apple also introduced the iPad mini in the quarter. Earlier Wall Street analysts predicted that Apple’s iPhone sales in the quarter may reach 47.5 million to 53 million, compared with 26.9 million in the previous quarter. Since the iPhone 5 is not widely available worldwide, there will be slight fluctuations in iPhone sales in Q4 2012. In addition, analysts expect the iPad global sales will reach 23 million to 25 million quarter.

After Apple's stock price hit a record high in September 2012, the cumulative decline has reached 30%. One of the most critical factors is that market participants worry that Apple's iPhone is not the world's most popular smartphone. With South Korea’s Samsung Electronics and other Android smart phone makers accelerating their pace of development, investors believe that the iPhone’s “one-size-only” situation will soon end.

According to a survey conducted by Thomson Reuters, the vast majority of Wall Street securities analysts surveyed gave "buy," "strong buy," and "hold" ratings on Apple's stock. Analysts’ target price for Apple’s shares in the medium term is US$745 per share, which is nearly 50% higher than the closing price of Apple’s stock ($700 per share) on Friday (local time on the 18th).

OLT SFP Module

SFP standardization:
SFP transceivers are regulated by a multilateral agreement (MSA) between competing manufacturers. SFP is designed according to GBIC interface, allowing a greater port density (the number of transceivers per inch on the side of the motherboard) than GBIC, so SFP is also called "mini-GBIC". The related small package transceiver (SFF transceiver) is smaller in size than SFP, but SFF is soldered to the motherboard as a pin through-hole device instead of being inserted into the side card slot on.
SFP transceivers have a variety of different transmission and reception types. Users can select the appropriate transceiver for each link to provide the "optical performance" that can be achieved based on the available fiber types (such as multimode fiber or single mode fiber). Available optical SFP modules are generally divided into the following categories: 850nm wavelength/550m distance MMF (SX), 1310nm wavelength/10km distance SMF (LX), 1550nm wavelength/40km distance XD, 80km distance ZX, EX or EZX with a distance of 120 kilometers, and DWDM. The SFP transceiver also provides a copper cable interface, so that host devices designed mainly for optical fiber communication can also communicate through UTP network cables. There are also wavelength division multiplexing (CWDM) and single-fiber "bidirectional" (1310/1490nm wavelength upstream/downstream) SFP.
Commercial SFP transceivers can provide rates up to 4.25 G bps. Several packaging forms of 10 Gbps transceivers are XFP, and a new variant "SFP+" which is basically the same as the SFP package.
