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

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

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

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

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

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

As for the concept of passive optical network, the PON standard based on ATM was proposed in early the 1980s, and the corresponding g.983 suggestion was defined by Itu/fsan, namely Apon. The author also participated in the meeting of the National TNS Optical Devices Working Group at the end of last year, and participated in the review of the communication industry standard of "ATM based passive optical network (a-pon) with 155mb/s burst Optical transceiver Module Technical Requirements".

Fiber-optic access networks are still commonly used. So I studied the new challenges of fiber-optic access networks to meet the "full-service" operation. I would like to share with you here, hoping they will be useful to you. Generally, end users only care about the service types provided by carriers and the "integrated" and "one-stop" experience. Therefore, only by providing integrated services can operators increase user loyalty and occupy a greater market share in the fierce competition. Stro

of optical line terminals (OLT), Optical Network Unit (ONU)/Optical Network terminal (ONT) and optical distribution network (ODN), the so-called "passive", refers to all ODN by passive optical splitter and optical fiber and other passive optical components, excluding any active nodes. The PON technology uses a point to a multi point topology, and the downlink light signal emitted by Olt is broadcast through a passive optical splitter to each onu/

features of the ATM network and is the most mature PON technology. GPON protocol:In ITU, the uplink/downlink rate is increased to 2.5 Gb/s through the GPON passive architecture standard, and is encapsulated using the general frame-based protocol (green code, in this way, value-added services such as voice, data, video, e-commerce, distance education, and telemedicine are more effectively supported on the

With the development of China's access industry, optical fiber access technology has become one of the mainstream technologies, and many branch technologies have emerged. GPON can meet the requirements of optical fiber access network. The increasing popularity of the optical fiber access market brings a rapid development opportunity for the new generation of optical fiber access technology. However, the debate over the future development of FTTH over

FTTH Fiber to household this seemingly distant thing began to enter the market in 2004, especially in Japan and North America has begun to scale applications, development is very rapid, thus becoming a weak optical communications market, and even recognized as the biggest driving force for the resurgence of optical communications. Affected by foreign countries, China in some areas (such as Wuhan) also began a small-scale FTTH test, some operators (such as Beijing Communications) even began a FTT
