As a new generation of Passive Optical Network (PON) technology, 25G PON and 50G PON have huge potential and development space. They provide higher data transmission speeds and greater bandwidth, which can meet the growing network needs in the future and promote the development and popularization of digital society.

As key components of optical fiber communication systems, OLT and ONT will face more challenges and opportunities under the evolving communication technology and application requirements. Future development trends will be mainly affected by new technologies such as 5G, smart cities and the Internet of Things. At the same time, innovative data transmission technologies and enhanced security will become key directions for the development of OLT and ONT.

In the optical network topology, the emergence of optical splitters helps users maximize network performance. An optical splitter is a passive optical device that can decompose an optical signal into multiple optical signal outputs, including one or two input terminals and multiple output terminals. When the optical network system needs to couple and distribute optical signals, optical splitters can be used to achieve this.

In ODN network construction, engineering laying and equipment costs are huge. For example, when installing optical cables, experienced workers need to use fusion splicers to splice optical fibers. Secondly, installation is difficult, and installation and maintenance operations affect network quality.

Fiber coiling is a technology as well as an art. The scientific fiber coiling method can make the fiber layout reasonable and eliminate fiber breakage caused by extrusion. Optical fibers are fragile. Excessive bending angles will damage or even break the optical fibers, causing communication interruption. The connection of optical fibers must go through multiple fiber splice closure.

Future development of Ethernet technology will continue to be driven by changing market demands and technical challenges. These trends will allow Ethernet to continue to adapt to emerging applications and technology requirements, maintaining its key position in the networking field.

Hollow-core fiber uses air as the transmission medium, replacing the traditional optical fiber that uses "glass core" as the transmission medium. With ultra-low latency, ultra-low nonlinearity, potential ultra-low loss and wider passband bandwidth, hollow-core fiber can help OTN systems achieve greater transmission capacity, longer transmission distance, and smaller transmission time delay.

This article introduces EPON, GPON, 10G EPON and 10G GPON in detail. EPON and GPON are two different optical fiber transmission technologies. They are both based on PON (passive optical network) technology.

Light decay generally refers to its luminous flux. When charging the surface of the photosensitive drum, as the charge accumulates on the surface of the photosensitive drum, the potential continues to increase, and finally reaches the "saturation" potential, which is the highest potential.
