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

What are the advantages of a small pluggable (SFP) port for a Gigabit Ethernet switch? How do I connect the four SFP ports of a d-link DGS 1248 t smart switch? I think the main advantage of the SFP port is the flexibility to connect to the network. The SFP port is a hot-swappable input/output device that can be plugg

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

The SFP is the abbreviation for the small FORM pluggable and can be easily understood as an upgraded version of the Gbic. The SFP module is half the size of the Gbic module, and can be configured with more than one port number on the same panel. The other features of the SFP module are basic and gbic consistent. Some switch vendors call the

1. What is GBIC? GBIC is short for Giga Bitrate Interface Converter. It is an Interface device that converts Gigabit electrical signals into optical signals. GBIC is designed for hot swapping. GBIC is an Interchangeable product that complies with international standards. The gigabit switches designed with GBIC interfaces share a large market share due to flexible exchange. 2. What is SFP?

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

These days, when HP acquired H3C, it was rare to see 3COM with 3 O-markers. But the problem, a year ago a project bought a 3COM switch 2924-SFP plus switch (PS: pure switch, no readable data). At that time saw a default management IP in the back, so log in to the Web interface configuration can be. Later the project bought H3C S5500 switch, do not have this switch, so idle.Due to the recent equipment is more tense, need to enable, the problem came, bu

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

How to disable the SFP module on H3C vswitches and other devices? The following warning is displayed: OPTMOD/4/PHONY_MODULE: GigabitEthernet1/0/2: This transceiver is NOT sold by H3C. h3C therefore shall NOT guarantee the normal function of the device or assume the maintenance responsibility thereof! This is a warning when SFP module is used on H3C vswitches, routers, and other devices. It generally means t

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

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

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

the port specification when purchasing the device. You only need to select the GBIC corresponding to the required transmission interface, and it is easy to make adjustments as needed. The current GBIC has a Small version (Small Form-factor Pluggable, SFP), also known as mini GBIC (mini GBIC ), The size is about half of the original size, which not only saves costs, but also doubles the port density of network devices. Term 3 Small encapsula

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
