Fiber Optic Splitter
Fiber optic splitter is an optical passive device used to realize the splitting and combining of optical signals. Fiber Splitter distributes the light energy which transmitted in one fiber to two or more fibers in a set ratio, or combines the light energy which transmitted in multiple fibers into a single fiber. PLC splitter is […]
The History of PON
Many people have questions about the relationship between EPON, GPON, 10G PON, XG-PON, and NG-PON 2. Today, through this article, Yingda will provide a detailed introduction, hoping to help you. EPON and GPON Let’s begins with the origin of PON. In the 1980s, with the rise of computer and multimedia technology, more and more people […]
The impact of insufficient fiber bending radius on ODN link attenuation
ODN link downlink attenuation is generally abnormal The GPON network uses 1490nm/1310nm wavelengths for both downstream and upstream, while the ODN (Optical Distribution Network) mainly uses G.652D and G.657A2 fibers, which have attenuation of 0.23dB/km and 0.36dB/km at 1490nm/1310nm wavelengths, respectively, as shown in Figure 1. Therefore, under normal circumstances, the downlink attenuation of the […]
Comparison of upstream and downstream speeds of PON
As we all know, OLT allocates light sources to ONUs, which can be understood as a commander, commanding ONUs under the PON port to send data within a specified time. PON can be classified as EPON based on the different transmission rates of upstream and downstream, GPON, 10GPON, XG(S)PON， The specific details are as follows […]
