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 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

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

We have introduced the SNMP protocol and the entire Technical System in the GPON technology. If you have any questions, you can refer to "SNMP protocol technology application example". Next we will discuss the software design in this regard. First, let's take a look at the SNMP protocol proxy. OLT-side SNMP protocol proxy To complete ONU control on the Management end, ONU must be managed on the OLT end. SNMP has good support for MIB and is simple, it

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 does not require the installation of traditional active devices between central bureaus and user stations. These active devices typical

GPON protocol StackFirst, the Gpon protocol stack is divided into two parts1. c/m plane----A, embedded OAM B, Ploam C, OMCI2, U (user) plane----A, high-level B, GTC layer C, physical layerSecond, c/m planeThe management control plane is divided into 3 parts:1, ploam Physical layer OAM, the main management delay requires low management, ONU registration, ranging, the establishment of OMCC, alarm information

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

Requirements Description:Since the use of telecom 200M fiber, the resolution card into a dog. Open the domain name around 3 seconds, the less common domain name is around 8s. Suspected telecommunications gateway has a problem, so want to let the router dial authentication , and then set the DNS resolution domain namemodified for the router Dial authentication, the domain name resolution is still unresolved, continue to follow! (Set Ali's DNS 223.5.5.5/223.6.6.6) still slow to parseSolution:Acces

Analysis on the reason of frequent drop of modem 1, if the ADSL modem just as bridging mode access, first through the ADSL Modem Web page to view the line attenuation, Snr margin (this value is normally 15-40db, if less than 10db, indicating that the current line quality is not good enough), line speed and other parameters, If these parameters are abnormal, plea

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
