In our latest article, we dive into the crucial role of the optical power budget (OPB) in fiber optic communications, focusing on its key impact on system reliability and efficiency. 🌐 https://lnkd.in/gvs5vtUB We explain how the OPB guides network design and strategy by managing signal losses from fiber connections, splitters, and environmental factors. 💡 Taking a practical approach, we discuss the challenges of accurately calculating the OPB and the need to plan for unexpected issues and aging. Our analysis shows that carefully determining the OPB is vital for keeping communication quality high over long distances. 📊

A new article was open to public. Power amplifiers, one of our main RF product lineups, are used for transmission lines of radio frequency (RF) signals. Its role is to amplify data communication signals converted from RF signals to the level to which an antenna can transmit it as a electromagnetic wave without distortion. The new article reveals the evolution, design, and packages of our power amplifiers. https://lnkd.in/gPfHsq7D

CWDM vs DWDM: What's the difference？ How to choose? #CWDM stands for Coarse Wavelength Division Multiplexing. CWDM systems typically transport eight wavelengths with a channel spacing of 20nm in the spectrum grid from 1470nm to 1610nm - on a single fiber. #DWDM stands for Dense Wavelength Division Multiplexing. DWDM systems can carry 40, 80, 96, or up to 160 wavelengths by utilizing a much narrower spacing 0.8/0.4nm (100 GHz/50 GHz grid) – on a single fiber. Wavelengths are typically from 1525nm to 1565nm (C-band), with some systems also capable of utilizing wavelengths from 1570nm to 1610nm (L-band) #wdm #cwdm #dwdm #networking #glsun

📡 #LPWAN Fairy Tale: Sending Data via Pigeon with #MQTT, #CoAP, or #LwM2M? The myth of MQTT and energy consumption. MQTT isn't suitable for #NBIoT, #LTEM, and #5G #NTN. MQTT is based on #TCP, designed for wired connections. Weaknesses of MQTT: - TCP requires acknowledgement during connection setup, payload, and at the end of communication, with a timeout. - MQTT also requires acknowledgement during connection setup, payload, and at the end of communication, with a timeout. 🔍 Advantages of CoAP over MQTT: - UDP doesn't require acknowledgement during connection setup, payload, and at the end of communication, with no timeout. - CoAP doesn't need acknowledgement during connection setup, payload, and at the end of communication. A timeout can be freely chosen. CoAP can operate without acknowledgement. 🐦 NB-IoT and our pigeons can't guarantee acknowledgement before TCP timeout. NB-IoT and LTE-M Release Assistance Indication (#RAI) don't offer acknowledgement reception. RAI has the lowest energy consumption with NB-IoT, LTE-M, and 5G NTN. Even the MQTT timeout can't be met by pigeons. The estimated flight time based on an average speed of 60 km/h is 8 hours and 20 minutes to our island, 500 km away from the mainland. No chance with MQTT. ⏳ NB-IoT and LTE-M have a latency of 10 seconds with high Link Budget or Maximum Coupling Loss (MCL). 5G NTN has a 40-second latency, with occasional packet loss. A moving object may send a packet but not receive it later due to poor connection, a challenge for MQTT but less so for CoAP. 🛰️ Writing only about CoAP is incorrect. CoAP can use UDP, SMS, NB-IoT Non IP, MQTT, or even pigeons. NFC is used to read packets at the pigeon loft entrance. For the return channel, we can use mobile, Wi-Fi, or Ethernet. 🤔 I hope that with CoAP via pigeon, it's clear why MQTT is unsuitable for wireless technology. If you encounter a debate on LinkedIn about MQTT versus CoAP from an MQTT fan from Discworld, send them the link to CoAP via pigeon. Before I forget – LwM2M versus MQTT is also just a marketing fairy tale. But more on that later. 👉 Subscribe to my #IoT #M2M Times (newsletter) on LinkedIn.

The future is #5G but 4G still pays the bills. How do you support both without increasing #PIM? #MOSAIC is the answer. With CommScope's MOSAIC platform, you can slide any active 5G radio directly behind the specially adapted 4G passive antenna; a unique RF window allows the 5G signal to pass through unimpeded while reflecting the 4G frequencies. No in-band or cross-band PIM—performance that’s tested and verified prior to shipping. Now, you can support passive 4G and active 5G without increasing your PIM risk or equipment footprint.

Our cooperation agreement with KT on 6G research is a testament to our long-standing partnership in co-developing advanced wireless technology solutions. 3GPP has laid out its 6G timeline and committed to developing the needed specifications, targeting mass commercial deployments around 2030. Nokia will actively participate in the standardization work, helping determine how 6G networks will be built and how the new capabilities can bring value to end users and the industry. Understanding the needs of our customers such as KT is essential for choosing the right path forward with 6G. Today, we can predict that 6G will bring more artificial intelligence capabilities into the network. The potential allocation of higher spectrum frequencies for 6G in the 7-15 GHz range will be an important enabler for macro cell grids that provide further performance gains, enhanced uplink coverage for high data rates and energy efficiency enhancements.

Great insight and summary of current market situation

The #Memory trading volume has decreased, the overall procurement of particulate gas has not grown, and most DRAM module producers have been slow to de-stock, so the current state of the market is not favourable for trading. However, the transaction momentum in the server #DRAM #RDIMM category is rather good, primarily because the original manufacturers' contract bids are relatively high, making the spot somewhat like buying petrol. Overall, there is some variability in the spot market's rise and fall trends for different terminal items, and the real terminal demand is the only basis for assessing the subsequent price trend. Over the course of the week, #DDR4 1Gx8 2666 MT/s had a 0.21% price increase (from US$1.945 to $1.949).

Interested in Fiber Sensing? Here's an abbreviation to know... #FBG - Fiber Bragg Grating. These advanced optical reflectors hold the key to precision in #fiberoptics, and happen to seamlessly integrate into Ensure's ultra-narrow linewidth #UNL lasers. Their Superpower 🦸‍♂️👇 FBGs, woven seamlessly into Ensure's UNL lasers, act as wavelength maestros, reflecting specific wavelengths with unparalleled accuracy. This unique ability: ☑️ Ensures wavelength stability ☑️ Reduces noise, and ☑️ Heightens sensitivity in our lasers. Why does having a narrow linewidth matter? A narrow linewidth translates to a more focused and precise wavelength emission. 🎯 This precision is crucial in fiber sensing applications, enhancing the sensor's ability to detect subtle changes for accurate and reliable results. Imagine #PerimeterSecurity in critical infrastructures. 🏢 Using an UNL laser in fiber sensing ensures detecting even the slightest disturbance, like an intruder breaching the perimeter, with exceptional accuracy. 🚨 The narrow linewidth allows for precise monitoring, providing real-time insights and enhancing overall security measures. The fusion of FBG technology with #UNLlasers results in linewidths as narrow as 1~3 kHz, making Ensure's lasers a reliable cornerstone in DVS/DAS systems. 🔒 #Fibersensors #FiberBraggGrating #RealTimeMonitoring
