1. WDM-PON bears 5G application scenarios 1.1 Pre-transmission network architecture definition With the rapid development of mobile Internet and the emergence of a variety of new applications such as the Internet of Things, in order to cope with the future explosive mobile data traffic growth and massive device connectivity, the fifth generation of mobile communication (5G) technology came into being. In 2015, ITU-R officially defined three typical application scenarios for 5G: eMBB, mMTC and URLLC. eMBB corresponds to large-capacity mobile broadband services such as 3D/Ultra HD video. mMTC corresponds to large-scale Internet of Things services, while URLLC corresponds to services such as driverless, industrial automation, etc. that require low latency and high reliability. On November 28, 2016, China Mobile released a white paper on the 5G C-RAN requirements, architecture and challenges.

What is the biggest advantage of MTP connector

图片
Multi-core transmission means more challenges At the heart of the MPO connector is the mechanical docking (MT) ferrule technology, which was launched by a leading Japanese telecommunications company in the mid-1980s for commercial user telephony services. This MT technology became the basis for the first MPO connector introduced in the early 1990s. The ever-changing communication technology is changing people's lives and putting forward higher requirements for network transmission performance. As bandwidth demand increases, the industry is evolving toward higher-density networks, which are multi-lane highways for data transmission. This heralds the beginning of today's parallel optics, or multi-core optical transmission. Due to the increase in "channels" used in parallel optics - the fiber that receives the received data requires an efficient, high-density interconnect. The design of the MPO connector has successfully established a compact method that can effectively ...

The Six Networking Requirements of Building 5G network

With the accelerating pace of 5G commercialization, discussions on 5G's landing applications are increasing. The new features of 5G provide an opportunity for a new round of rapid development of bearer technology. In terms of performance, 5G brings the advantages of greater bandwidth, ultra-low latency, and high-precision synchronization. Compared with the current 4G network, these three core advantages have greatly expanded the practical space. Among them, the Internet of Things is one of the most highly anticipated areas. However, in the process of realizing large-scale practical use of 5G, there are many obstacles to the necessary aspects, and various technologies are needed to realize networking. Among them, there are six major network requirements such as multi-level bearer network, flexible connection scheduling, hierarchical network slicing, intelligent collaborative management and control, 4G/5G hybrid bearer and low-cost high-speed networking. In the process of network con...

What is the difference between G.654 and G.652 fiber?

With the increase in traffic demand and the development of the Internet of Things and 5G, operators and equipment manufacturers began to consider higher bandwidth to meet the needs of users for high-definition, ultra-high-definition services such as 4k/8K, G.654 fiber. Therefore, it has received more attention. From a technical point of view: compared to G.652 fiber, G.654.E fiber has no obvious advantages in power-free relay distance, which can extend the transmission distance of no-electric relay, up to 900km or more, and reduce the setting of relay station. From the perspective of comprehensive cost, fiber optic cable, transmission equipment and office energy consumption, combined with cost considerations, increase the cost of some of the fiber. The use of G.654.E fiber increases the cost of fiber optic cable compared to G.652.D fiber, but the integrated measurement system saves investment and increased investment in fiber optic cable. G.654.E fiber has a slight advantage over G.652...

Introduction to Several Common Fiber Optic Connectors

A fiber optic connector is a detachable, removable, re-plugged connection device that connects one fiber to another, also known as a fiber optic splice. It enables low-loss connections between fibers or between fiber and cable, effectively reducing the impact of fiber connections on the signal. The fiber optic connector is mainly composed of four parts: a pin, a connector body, an optical cable, and a connecting device. Fiber optic connectors need to meet many requirements in terms of characteristics, including fiber optic transceiver insertion loss of less than 0.5dB, return loss greater than 25dB; fiber optic connector tensile strength greater than 90N; fiber optic transceiver operating temperature range of -40 ° C ~ 70 ° C, more than 1000 insertions and so on. Depending on the transmission medium, the fiber optic connector can be divided into a single-mode fiber connector and a multi-mode fiber connector; and depending on the connector structure, it can be divided into an  LC fi...

What is LSZH Sheath in Fiber Optic Cable?

LSZH is  Low Smoke Zero Halogen  for short. LSZH has been widely applicated in cable jackets,specially when the fiber optic cable been installed indoor or some specially environment. What are halogens and why are they dangerous? Halogens are a group of highly reactive elements including fluorine, chlorine, bromine, iodine and astatine. When products containing halogens are burned, they produce very dangerous gasses. Public awareness of these dangers began after several tragic fires claimed the lives of victims who inhaled deadly halogenated fumes. Several fires, including those at the Beverley Hills Supper Club, London's Kings Cross Underground Station and Germany's Düsseldorf Airport, have lead to important changes that significantly limit where cables containing halogens may be used. Many organizations, local authorities and governments have undertaken broad initiatives to eliminate the production of halogenated material. In Asia, the United Kingdom and many European c...
