📌 Modulation in Telecommunication As Telecom engineer or professional, you should understand modulation. 📍 The technique of altering a signal or waveform to convey data or information is referred to as modulation. The goal of modulation is to facilitate efficient information transfer across a communication channel. 📍 In communication systems, including audio, video, and data, can be represented by these signals. This data is embedded onto a carrier signal through modulation. 📍 Key Points in Modulation: 👉 Modulation is used in microwave links , wdm optical , RF(GSM WCDMA LTE and 5G) 👉 There is analog and digital modulation. Focus is on digital modulation. 👉 Common types of digital modulation used is QAM. 👉 In QAM, amplitude and phase is used to achieve high levels of spectrum usage efficiency. 👉 We can use from 4QAM to 8192 QAM. There can be more. 👉 In increasing the modulation order, the link capacity increases, and the expected bit error rate increasing too. 👉 For example when we use 1024 QAM then we have 1024 symbols of data. and each symbol represents 10 bits of traffic. 👉 We have 2 types of modulation control : ✅ Fixed modulation , may used with TDM traffic ✅ Adaptive modulation which suitable to be used with hybrid and IP traffic , 👉 Take note that TDM means legacy PDH and SDH for 2G as an example. Why Modulation is Needed: 1. Efficient transmission over long distances: ✅ Low-frequency audio or data signals have limited transmission range due to attenuation and interference. Modulating them onto a high-frequency carrier wave creates a signal with improved propagation characteristics, allowing for efficient transmission over longer distances. 2. Multiple signal transmission: ✅ Modulation allows multiple transmitters to share the same medium (like airwaves) without interference. Each transmitter uses a different carrier frequency for its modulated signal, enabling simultaneous transmission and reception of numerous signals. 3. Improved antenna size and efficiency: ✅ High-frequency carrier waves require shorter antennas compared to low-frequency signals. This makes communication equipment more compact and portable. Additionally, antennas tuned to higher frequencies often exhibit better radiation patterns, improving signal strength and coverage. In conclusion, modulation is of paramount importance in modern communication systems and has revolutionized the way information is transmitted across various mediums. It is now an essential component of wireless communication, broadcasting, data transfer, and many other applications due its effectiveness, noise immunity, and compatibility.

Coherent optical technology uses phase, amplitude, and light polarization to dramatically increase data transmission rates and fiber capacity. At the heart of this technology are coherent optical engines, and 5G Technology has an excellent article on how they work. Consisting of digital ASICs, analog electronics, and photonics, these engines use advanced modulation techniques like PM-QPSK and PM-QAM to pack more data into each symbol. These techniques deliver speeds from 100 Gb/s to 800 Gb/s and beyond. The market has split into high-performance embedded engines for long-haul applications and compact pluggables for metro networks. As we push towards 1.6 Tb/s and higher, challenges arise from Shannon's law and spectrum limitations. Solutions include expanding into L-band frequencies and developing Super C and Super L configurations. At Belden, we want to ensure our customers have robust, high-capacity networks that are ready for the future of data transmission.
