The main reasons for ONU weak light are two aspects: equipment reasons and excessive attenuation of ODN link. Because equipment issues are easy to detect and eliminate them from the network management system
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
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
In the design of broadband fiber optic access projects such as FTTH, the full attenuation of the ODN fiber optic link needs to be calculated
The article “How to Calculate the Full Range Attenuation of ODN Fiber Optic Link” introduces the calculation method of the full range attenuation of ODN
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
There are mainly two types of optical distribution network (ODN) splitting methods: primary splitting and secondary splitting, as shown in Figure 1. Due to the
PON is the main technology used for fiber optic broadband access. It has been 15 years since China Telecom began large-scale commercial use in 2006,
FTTR Description Before we talk about FTTR, let’s talk about what FTTx is. FTTx is the abbreviation for “Fiber To The x”, referring to “fiber
Although ODN of FTTH access engineering test only includes attenuation, the testing process is very complex according to the requirements of the “Communication Line Engineering Acceptance
Optical fiber access network refers to the application form that uses optical fiber as the main transmission medium in the access network to realize user
