Pay attention to the suitability of choosing ppe

Recently, I heard feedback from front-line sales colleagues. When participating in some wireless bidding projects, many of the tender bids required that the PoE switch used by the wireless device must be the same brand as the core switch in the equipment room. In fact, do we really need to do this? 10 years dedicated to the development of PoE switch Fengrun Da to explain.

From the perspective of principle and practical use, switches in the network are not producers of data packets. The producers of real content are terminals (PCs, mobile phones, and tablets), and the switching equipment is only responsible for the forwarding of data packets. Therefore, as long as the standard 802.3 related PoE switches, such as IEEE802.3ab (gigabit Ethernet standard), IEEE802.1Q (VLAN standard), IEEE802.3z (gigabit Ethernet fiber standard), etc., can be built on the network. General purpose, and compatible with standard equipment. Therefore, it is ridiculous to say that a unified brand will make data compatibility better.

In wireless coverage, PoE switches provide power for wireless APs, and play the role of Layer 2 data exchange and division of different VLANs. Generally, each vendor will comply with standard protocols and be a relatively technically mature device. In actual use, we often encounter users who have switches from multiple vendors at the same time due to capacity expansion or device upgrades, and have never encountered incompatibility issues.

The requirement to use the same brand is as meaningless as requiring the same brand in the network (eg, PC, cell phone, PAD). The emergence of such brand restrictions in wireless construction projects is often caused by users being guided by Other vendors for other considerations, thus making it impossible for users to choose more specialized wireless products.

In fact, wireless deployment should return to the essence. It should pay attention to the security, speed, and value of wireless itself. Wireless device manufacturers should also proceed from the nature of customer needs to provide customers with a more professional and secure wireless network.

Nowadays, the electronics industry has continuously improved the requirements for non-workshops, more and more sophisticated products, and the requirements for the production environment have also continuously improved.

The dust-free workshop refers to the removal of pollutants in air, such as fine particles, harmful air, and bacteria in a certain range of space. The temperature, cleanliness, indoor pressure, air velocity, and airflow distribution, noise, vibration, and lighting, and electrostatic control Within a certain range of requirements, a specially designed room is given. That is, no matter how the external air conditions change, the interior of the room can all have the characteristics of maintaining the cleanliness, temperature, humidity, and pressure properties originally set.

The main difference between the Class 1000 clean room and the Class 100 clean room is that the dust particles have different capacities.

1. The dust-free particles in the 0.5-micron clean room are less than 90 million; the dust particles in the 0.5-micron clean room are less than 9 million; the dust particles in the 100 clean room are 0.5 m less than 2 million. Clean room 5 micron dust particles less than 600,000, 1000 clean room 5 micron dust particles less than 50,000., 100 clean room 5 micron dust particles less than 10,000 (not allowed)

Market prospects, infinite beauty

According to relevant information and data show that in 2002 the total market for Chinese underwear more than 600 billion, and the underwear market at 30% annual growth rate. Due to the particularity of the industry, the competition among them mainly manifests in the relatively low level of competition such as product competition, channel competition and price competition; there are few or no brands that genuinely drive sales; the leading brands have a very small market share , No one underwear brand market share can exceed 10%, underwear industry aircraft carrier is far from yet. So, for every underwear brand, there is a huge space for growth and development. Another data show that the knowledge of Chinese women's underwear is very scarce, more than 80% of women have the wrong underwear phenomenon. Chinese women's underwear consumer awareness has yet to be improved, the underwear market also needs the strong underwear manufacturers to guide cultivation, to work together to make this piece of cake. At present, the underwear business is facing the main problems of lack of talent, inventory pressure and the old marketing model, etc., and underwear industry associations around the world are usually only nominal, the industry lacks the existing market rules, which directly constrain the development of underwear industry . With the involvement of more and more underwear brands, the competition in the industry is bound to intensify. Some small and medium-sized brands with relatively weak competitiveness will also be eliminated.

Especially in recent years, underwear stores, underwear supermarkets, underwear fashion hall, underwear bar and other new underwear sales terminals have emerged, underwear more and more as a fashion culture to operate, the underwear industry's prospects will be even more beautiful. Zhuoya lingerie brand positioning in the new city of intellectual women's large chain underwear business, chain stores in nearly 30 cities in the Pearl River Delta region, the company has a unified image, the scale of the chain stores nearly 300 and plans in 3-5 years , With the principle of "joining Zhuoya beauty and joining hands in creating a win-win situation", we have developed 500-1000 chain stores, franchise stores and franchise chains nationwide and achieved the expected goal of leapfrog development.

The optical splitter offer is one of the most important passive components in the optical fiber link, and its function is to split one light into multiple outputs in a certain proportion. Optical splitters are similar to splitters and distributors in cable transmission networks. In practical applications, optical splitters are often used to split the optical signal output from the optical transmitter into several outputs with different intensities. The optical output is transmitted all the way to more distant devices. Near distance, so that all optical nodes can get approximately equal optical power. Before designing the optical splitter, it must be familiar with the optical splitter specifications. Its main indicators are the following:

1, additional loss optical splitter to the input optical signal in accordance with the predetermined split ratio for each branch is allocated, the optical signal through the optical splitter in addition to splitting loss, there are optical splitter itself to the optical signal The loss is called the optical splitter additional loss.

The additional loss is the most basic technical indicator of the splitter, and it has intrinsic links with other performance indicators. Therefore, the additional loss is not only a measure of the optical performance of the device, but more importantly it is also intrinsically linked to the device's seismic performance, temperature stability, and lifetime. For this reason, when we use optical splitters, we must strictly screen this indicator for manufacturers.

2. Ratio of optical power splitting ratio of optical splitter to each branch optical power is called splitting ratio, which is defined as the ratio of the output optical power of an output end of the optical splitter to the total output optical power of the output end of the optical splitter. .

This indicator is the most important design index parameter of the optical link and is explained in detail later.

3. Deviation of spectroscopic ratio The spectrophotometric deviation refers to the deviation between the actual spectroscopic ratio and the design value when the splitter is manufactured. This deviation makes one light increase and the other light decrease. Essentially it does not affect the total output power.

Because the distances from the transmitter to the optical nodes are different, in order to ensure that the received power of the receiver is consistent, the splitter ratio of the splitter should correspond to the transmission distance. That is, the longer the transmission distance is, the larger the ratio of the splitting light to the optical path is. If there is an error between the actual splitter and the designed split ratio, the received power at the receiving end will be inconsistent. At present, domestic manufacturers are fully capable of controlling the split ratio error of 1×N optical splitter within ±0.5%.

4. Divided light loss Divided light loss: The loss of the optical signal generated by different splitting ratios is called splitting loss. Its value is -10 lgK (K is the splitting ratio).

5. Insertion Loss The insertion loss includes two parts: the splitting loss and the additional loss, that is, the insertion loss (dBm) = -10 lgk + additional loss.
