　　As we all know, wireless modules have two common performances. The following small series with outstanding skills will introduce the comparison of the two performances.In the past ten years, radio Module Defeated many competitors, courageously advanced in the struggle, and polished many good products for customers. https://www.hkulike.com/

　　

　　Firstly, the instantaneous frequency of the FM carrier transmitted by the FM transmitter is that the FM wave that changes with the modulation signal is an equal amplitude wave, and its maximum power is equal to the average power; The amplitude modulation transmitter emits an amplitude signal, and the maximum transmission power is equal to 4 times the average power. If the last stages of AM transmitter and FM transmitter use the same type of power tubes, and both are estimated according to the maximum power, the power emitted by FM transmitter is four times the average power emitted by FM transmitter.

　　

　　The main feature of FM is its strong anti-jamming performance. The so-called strong anti-jamming performance mainly means that the signal-to-noise ratio at the output of FM receiver is greater than the signal-to-noise ratio at the output of FM receiver under the same input signal-to-noise ratio.

　　

　　The reason why FM has stronger anti-jamming ability than AM can be analyzed from the power of the transmitted signals of the two systems. The power of the side frequency component of FM wave is divided from the carrier power. Its sidebands are not only numerous, but also increase in amplitude, which means that the proportion of power converted into sidebands in carrier rate is large, and the maximum power of sidebands of amplitude-modulated waves is equal to that of carrier power. Therefore, FM has more side frequency power than AM, which means it is more capable of overcoming the noise and interference in the channel or the machine.

　　

　　Secondly, we can make a comparative analysis from the mediation of receiving signals. Because the information of amplitude modulation signal is contained in the amplitude of the amplitude modulated signal, the demodulated envelope detector can’t suppress the parasitic amplitude modulation interference, while the information of FM signal contains the frequency change at the moment of high frequency oscillation, so the parasitic amplitude modulation caused by interference can be removed by limiter.

　　

　　Therefore, the anti-interference performance of FM system is better than that of AM system, regardless of the sideband power of the transmitted signal or the demodulation of the received signal.

　　Optical fibers and network cables have different interface standards. Wired networks typically use an RJ45 port, while optical fibers require an adapter, making the process more complex and requiring expensive tools, which are not ideal for personal use. Additionally, installing, testing, and replacing network cables is straightforward, making them suitable for short-term use scenarios. On the other hand, optical fibers have higher maintenance costs and are better suited for long-term applications. Although optical fibers themselves are relatively inexpensive, the cost of splicing them ranges from 20 to 50 yuan per splice. As the number of splicing points increases, so does the overall cost. Moreover, optical fiber networking requires compatible network port-switching equipment.Actually, it’s not just this reason, network cable Its own advantages are also obvious, and it is normal for the market to perform well. https://kechengdg.com/

　　

　　In summary, both manufacturing and maintenance costs for optical fibers are higher compared to network cables.

　　

　　optical fiber

　　

　　While optical fiber offers superior transmission speed compared to network cables, it is not suitable for all scenarios. The optical fibers commonly used in current project networking are primarily single-core sheathed cables, costing about 0.5 yuan per meter. However, these sheathed optical cables are more prone to breakage, particularly at the joints, when compared to network cables.

　　

　　optical fiber

　　

　　In today’s networking setups, a combination of network cables and optical fibers is often used, and it is unlikely that network cables will be entirely replaced by optical fibers.

　　If the mobile phone uses GPRS DTU on the Internet, data can be sent and received in groups, which means that users are always online and charged according to traffic, which quickly reduces the service cost. If CSD bearer is changed to GPRS, it means that dozens of people will bear the cost of the original one. Therefore, many unnecessary expenses will be greatly reduced.according to Wireless Module Industry veterans said that its development will still be in a good situation. https://www.hkulike.com/

　　

　　The advantage of GPRS DTU is that its data transmission speed is not comparable to that of GSM. At present, the transmission speed of GSM mobile communication network is 9.6K kilobytes per second, and the transmission speed of GPRS mobile phone has reached 56Kbps when it was launched at the beginning of this year, and now it has reached 115Kbps. Packet is to package Data into many independent packets, and then send these packets one by one, which is somewhat similar to sending a package. The advantage of packet switching is that it only takes up bandwidth when there is data to be sent, and it can be priced according to the amount of data transmitted, which is a more reasonable charging method for users, because most of the time and bandwidth of data transmission like the Internet are intermittent.

　　

　　GPRS DTU can provide four different coding methods, which also provide different error protection capabilities. Using four different coding methods, each time slot can provide different transmission rates. Each user can use up to eight time slots at the same time. So GPRS DTU is called high transmission rate.

　　What is Fiber Optic Cable?

　　

　　Fiber optic cables transmit data in the form of light pulses through flexible, optically pure glass. These cables consist of five main components: the core, cladding, coating, strength members, and outer jacket.

　　

　　- Core: Made of high-purity silica (SiO2) with a small amount of dopants, the core is responsible for transmitting light pulses generated by lasers or light-emitting diodes (LEDs).

　　

　　- Cladding: This thin layer of glass surrounds the core and has a different refractive index to reflect light back into the core, allowing the signal to propagate.

　　

　　- Coating: Designed to absorb shock, prevent excessive bending, and protect the core.

　　

　　- Strength Members: These components shield the core from excessive tension and compression, particularly during installation.

　　

　　- Outer Jacket: Provides protection from external factors like shock, moisture, and other environmental influences.

　　

　　optical cable

　　

　　Tips for Choosing the Right Fiber Optic Cable

　　

　　1. Cable Type

　　

　　First, determine whether you need single-mode (SM) or multimode (MM) fiber optic cable based on your network application and specifications. Generally, SM fiber is ideal for long-distance and outdoor applications, while MM fiber is suited for short-distance and indoor use.

　　

　　2. Fiber Core Count

　　

　　After selecting the fiber type, calculate the number of fibers needed for your network. This depends on the scale of your FTTX (Fiber to the x) and ODN (Optical Distribution Network) projects and the type of fiber optic cable you plan to use. Backbone cables typically range from 24 to 288 cores, while distribution cables require fewer cores. FTTH home cables usually have 1 or 2 cores.

　　

　　3. Deployment Environment

　　

　　Consider the structure and material of the fiber optic cable based on its deployment location:

　　

　　- Outdoor:

　　

　　For direct burial, loose tube layer-stranded armored fiber optic cables offer the best protection. In overhead environments, self-supporting cables that can bear their own weight, such as figure-8 or ADSS cables, are ideal.

　　

　　- Indoor:

　　

　　Flame-retardant, low-smoke, halogen-free (LSZH) cables are essential for indoor use. In duct environments, choose cables with flame-retardant and LSZH properties. For exposed indoor environments, the same LSZH cables are required. Tight-buffered optical fibers, known for their small bending diameter, softness, and easy stripping, are well-suited for indoor applications.

　　

　　- Buildings:

　　

　　When laying cables vertically or horizontally within a building, tight-buffered, bundled (D-type), or branched (B-type) optical cables are recommended.

　　

　　4. Connectors

　　

　　Connectors are crucial for establishing a secure fiber optic network. Common types include ST, FC, SC, LC, and MTP/MPO connectors.

　　

　　- ST: Popular in telecommunication networks, spring-loaded for easy connection and removal.

　　

　　- FC: Threaded body, ideal for high-vibration environments, polarized fiber, and SM fiber.

　　

　　- SC: Snap-on connector, commonly used in SM fiber, duplex networks, CATV, media converters, and FTTX.

　　

　　- LC: A standard ceramic ferrule connector, half the size of SC, used in SM fiber, data centers, LANs, FTTH, and CATV.

　　

　　- MTP/MPO: High-performance multi-core connectors for data centers.
