gigabit passive optical Network (GPON) can provide the path of the network evolution and the bandwidth needed to transfer the new business in the current market technology. Advantages of PON structure Compared with the traditional network structure, PON has the following advantages: Since PON is called passive, it
I will not go into details about the advantages of EPON and GPON. The main points are as follows: 1. Saving money. This is an absolute principle. 2. high bandwidth, with a bandwidth of 1 to 25 GB 3. High Reliability. Optical splitter can be used in the middle, and no switch is required. Why do I save money by using EPON? PreviousArticleLet's talk about saving optical fiber for the moment. Let's talk about this transceiver. The price of a 1-to-60
