, IP multicast, POTS, T1). Ethernet pon a unique performance is ONU in addition to receiving optical signals and conversion, but also provides a 2nd, 3-layer Exchange function, allowing enterprise business within the ONU to implement routing. The Ethernet pon can also use a 3rd wavelength to transmit the image business. Since ONU is located in each FTTB and FTTH application, the cost will be shared among multiple users, and the design and cost of ONU is a key factor in the construction of the E

small DSLAM applications. Supports ADSL2 +, VDSL2, POTS, LAN, SHDSL, and other types of broadband access; supports GE/FE, EPON/GPON, 10G-EPON, and many other uplink connections; supports point-to-point (P2P) and point-to-point (P2MP) applications, supports star, chain, ring and other networking methods. A lot of data is mosaic.The appearance of the previous graph is long. This is how it is split. Well, to put it bluntly, the line is from this devi

generally refers to the business aspect of the green line, such as the business PDU, link layer code word, or the business management information of the Green Line. The net load is divided into three parts: the net load header (4-64 bytes), the net load information domain, and the Net Load FCS domain (4 bytes ). The first two parts are indispensable, and the third part is optional.This section describes three common and standard encapsulation protocols for data services, pos interfaces include

The other is the requirements of network components, the requirements for WT-144, on the broadband control there is a WT-134 completed, the WT-146 is being completed, there is a WT-147, and finally the broadband home, we are improving wt-135, there are a lot of terms here, and we have a lot of work in progress. We have to combine a wide range of industries to do this. External Contac

This solution can be applied to the network environment with ADSL Broadband. In general, there are Internet access needs in the school library, step-level classrooms, and dormitories. However, the network needs and environments in each place are different. Under normal circumstances, the library and dormitory fixed terminal and mobile device coexist, so

transmission: the traditional MSTP Technology and the PWE3/MPLS-based grouped transmission technology. With the IP transformation of the transmission network, PWE3/MPLS technology has become a key demand in the mobile bearer field. TD-SCDMA, CDMA, Wi-MAX and LTE (including TD-LTE and FDD-LTE) have requirements for time synchronization, currently only GPS or IEEE1588v2 can meet the requirements. Due to the frequency impact, the coverage capacity of the LTE access bearer network is less than 2G/3

In recent years, the main development trends of optical communication technology include capacity improvement, further intelligence, optical transmission of Carrier-class Ethernet, and fiber-to-the-Home. Along with the development of these technologies, optical communication testing technology has also developed rapidly. The development of the optical communication industry depends on the drive of the market and the development of technology. In recent years, the main development trends of optic

The so-called low-cost FTTH should be less than 2000 yuan or even 1000 yuan per line. Only in this way can FTTH be widely used and developed in China. 2. FTTH access technology in line with national conditionsThe technical solution to implement FTTH directly determines the manufacturing cost of FTTH equipment. At present, there are two m

Mippo Ethernet: Enables Ethernet networks to be transmitted through multiple wavelengths or multiple light waves or a single optical fiber, thereby greatly increasing network capacity. CWDM: Compared with DWDM, CWDM is more suitable for building a metropolitan network, it transmits a small number of wavelengths in one fiber, while CWDM equipment is cheaper and consumes less power, some manufacturers have already introduced the CWDM GBIC used in the switch

new product uses existing metal telephone lines to achieve high-speed broadband access technology of Mbps and high-quality transmission, meeting the needs of communication operators to build next-generation networks and provide high-reliability broadband communication services. Features of the new product are as follows: 1. Bidirectional symmetric Mbps transmission speed, which can be upgraded from ADSL The new product uses ADSL2 access technology to provide broadband access technology. The upl

server that logs on to the network center for verification, then you can access the resources with the corresponding permissions. Then, the remote host sends encrypted information to the VPN device in the enterprise network center over the Internet. When the data packet arrives at the target VPN device, the data packet is unwrapped, and the digital signature is verified and decrypted. Remote broadband access through VPN In this solution, VPN devices choose Avaya VPN gateway products, network ce

At the same time, because the access optical fiber at the end of the access network cannot have multiple routes, the replacement method of the optical fiber full protection has no practical significance. Therefore, the backbone optical fiber protection switching method will be the main protection switching method to improve the reliability of the EPON system in network applications. 2. Existing optical fiber protection solutions in the EPON system EPON international st

-household difficulties, it is also possible to consider introducing vectoring/g.fast technology to increase the copper wire rate to 100m~1g (along with the shortening of the copper wire distance to improve packet loss and delay). In addition, other technologies can be used to enhance the experience, such as the deployment of TCP acceleration technology in the network to increase TCP throughput and improve the TCP-mode VOD experience. The test results show that TCP acceleration is more effective

modulation technologies to reach the above objectives. However, there is no free lunch in the world. To improve the performance of one aspect, you have to sacrifice the other. For example, if the redundant information of channel encoding is added too much, the effective transmission rate must be reduced, and the redundant information is too little to reach the low bit error rate, so we must weigh it. Shannon proof that the Shannon limit Eb/N0 =-1.6db, bit energy/noise power is less than-1.6db,
