Welcome to call for the HYA235 * 2 * 1.0 cable in the Tianlian region

Description :

　　Advantages of power line broadband carrier communication method: 1. Broadband carrier is based on widely validated TCP/IP network technology, with complete link layer and network layer data protection and verification, far from being comparable to various lightweight node organization and relay algorithms.

　　2. Broadband carrier communication has a high speed and can complete data transmission in a very short time, greatly reducing the impact of sudden interference. Even if communication fails once, it can be quickly resent to ensure data reliability.

　　3. Most broadband carrier chips are manufactured based on high-performance 32-bit cores and DSP technology, which have advantages in both technical level and performance.

　　4. In addition to data encryption at the application layer, broadband carriers support high-strength encryption algorithms such as DES, 3DES, AES at the link layer, ensuring high data communication security.

　　5. Even in communication distances where narrowband carriers have advantages, broadband carriers can fully meet the application needs of most areas through high-performance modulation methods such as OFDM and a well-established relay networking mechanism.

　　6. Broadband carrier communication has high performance, fast speed, and strong scalability, and can load various network applications. However, its cost has not increased much compared to narrowband carriers, making it cost-effective.

　　Development and Reflection on Fiber Optic Cable and Communication Cable Technology 1. Expand the transmission capacity of a single wavelength. Currently, the transmission capacity of a single wavelength has reached 40Gbit/s, and research on 160Gbit/s has begun. Transmission above 40Gbit/s will pose certain requirements for PMD in optical fibers. At the ITU-TSG15 conference in 2002, the United States proposed the introduction of a new fiber category (G.655. C) for 40Gbit/s systems and suggested in-depth exploration of some issues in PMD transmission. Perhaps in the near future, a specialized 40Gbit/s fiber type will emerge.

　　2. Realizing ultra long distance transmission and relay free transmission is the ideal for backbone transmission networks. Currently, some companies have been able to use dispersion equalization technology to achieve relay free transmission of 2000-5000km. Some companies are further improving their fiber optic specifications by adopting Raman optical amplification technology, which can greatly extend the distance of optical transmission.

　　3. To adapt to the application of DWDM technology, the 2 × 2.5Gbit/s DWDM system has been implemented, and the 64 × 2.5Gbit/s and 32 × 10Gbit/s systems are under development and have made good progress. The widespread use of DWDM systems has raised higher requirements for the nonlinear performance of optical fibers. The ITU-T standard for the nonlinear properties and testing methods of optical fibers (G.650.2) has recently been completed. Once the nonlinear testing indicators of optical fibers are clear, corresponding indicators will be proposed for the effective area of optical fibers, especially for the further improvement of the nonlinear characteristics of G.655 optical fibers.
