Optical fiber requirements for G and G Systems
With the rapid development of data communication and interconnection networks, network point-to-point, online applications, and video services have all experienced explosive growth. Massive digital media content has led to a rapid increase of 10 or even times of Internet traffic, this results in 50% ~ The speed of 80% is growing rapidly. At present, the GB system has been commercially used by major c

Demand practice (5) detailed demand period (II)What is different from the business modeling period is that I don't spend any time discussing what needs to be done, because there is no big difference between practice, attention, and business modeling. In terms of the complete process, methodologies such as RUP and XP are much better than I have mentioned. Therefore, I will focus on some puzzles and thoughts in my actual work.1. rethink the relationship with other stages.At the end of the previous
Because COB does not have IC sealed Leadframe (Guide frame), but uses the PCB to replace, so the PCB welding mattress design Handy is very important, and fihish can only use electricity plated gold or enig (isotopes leaching gold), whether the Gold line or aluminum line, Even the latest brass lines have problems that can't be beaten up.PCB Design requirements for COB

Pc=pv/t*c*t*fWhere the PC is the number of concurrent, T is the observed time, that is, the length of time to produce PV, such as 14 hours a day produced 200,000 concurrent, then the formula t=14*60*60 seconds, pv=20 million. C is the number of HTTP connections requested by a single page, T is the duration of the connection, generally take an estimate of the length of time the user waits for a connection, for example, the user waits 5 seconds on average to find the Web page is not open, then thi

Software requirement analysis is to make the feasibility analysis of software during software planning to be refined and refined, analyze various possible solutions, and assign to each software element. Demand analysis is the final step in the software definition phase, which is to determine what the system must accomplish, which is to put forward complete, accurate, clear and specific requirements for the target system.For the
