Comprehensive comparison between GPON access technology and EPON

At present, the GPON Access Technology in China has developed very rapidly. Many people may not know the characteristics and advantages of the GPON access technology and EPON. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. The arrival of the 3G era will greatly promote the demand for network bandwidth, while the second

The network front-end is the management and control center of the entire system, is the interface between peop

Gpon is the best way to transition to full ip/ethernet network

standards have only matured in recent years and have been commercially available. The initial criteria were developed for Apon (also known as Bpon), which is characterized by the adoption of an ATM architecture approved by the International Telecommunication Union (ITU) in the mid 1890s. Apon uses ATM encapsulation to deliver voice and data, and all businesses use ATM for transmission via PON. In recent years, IEEE has introduced a standard based o

Encryption and error correction in AES&FEC gpon

The recent testing process has encountered a case of system AES and FEC, here is a brief introduction to their principles and applications in the Gpon system.Aesfor the gpon system, the downlink data is sent by broadcast to all ONU, involving a malicious user to eavesdrop on all broadcast frames, so the system introduces the AES encryption algorithm. It is a packet encryption algorithm, that is, the plainte

WTD releases RoHS compliant GPON three-way modules and devices

As the industry-leading optical module device manufacturer, WTD has recently released the Triple-play GPON series. GPON three-way device is completely based on the ITU-T G.984.2 Class B + standard design, to meet the-40-+ 85 deg C Industrial temperature requirements, the uplink rate is 1.25 Gbps, the downlink rate is 2.5 Gbps. The device has passed the reliability test. At the same time, WTD for the three

GPON protocol Stack Parsing

Why use EPON and GPON? Analysis on the network cost of m in villages

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

Gpon Optical fiber access to build full service broadband

business broadband network, the broadband access network is undergoing profound changes. On the one hand, xDSL technology gradually from adsladsl2adsl2+ to provide a higher bandwidth VDSL2 upgrades, which also requires vdsl2dslam closer to the user side. With the increase of the number of VDSL2 Zhi, the requirement of efficient aggregation of large quantities of dslam is put forward. On the other hand, fiber is rapidly replacing copper wire as an ideal access medium because of its natural defec
