Transmission medium is single-mode fiber, can choose single fiber, also can choose double fiber. A onaccess5xxx optical switch can connect up to 24 users of the ONACCESSH1001 Optical Network unit, ONACCESSH1001 can also line up to 4 computers or IP telephony. If the user has only one computer can choose OnA

An OnAccess5xxx optical switch can connect to the OnAccessH1001 optical network unit of 24 users. OnAccessH1001 can be connected to up to four computers or IP phones at the same time. If you only have one computer, you can select the OnAccess1001 Optical Fiber Nic to be inserted into the computer and directly connect to the optical fiber. The

communication and CATV access cable Resources in the residential area belong to all operators. Another feature of China's FTTH target market is the existence of industry barriers in the telecom business: telecom operators are not allowed to operate CATV services, and this situation cannot be changed for quite some time in the future. 2. Selection of FTTH Optical Fiber Access Technology in China1) Passive O

commercial buildings, are generally equipped with communication equipment rooms for installing communication access equipment and line handover for the entire residential area, this configuration is required for telecom operators to compete with each other and comprehensive access to a variety of telecommunication services. The distance between data centers and users is generally less than 1 km; major telecom operators and cable TV operators have already laid 4 to 12 cores in general.) optical

Urban residential areas are generally garden-type residential areas, which are characterized by high household density, A single Garden Residential Area generally has-households, and some even tens of thousands of households. residential areas, including commercial buildings, are generally equipped with communication equipment rooms for installing communication access equipment and line handover for the entire residential area, this

As The first company in China that specializes in R D and production of Fiber To The Home-FTTH equipment, we have recently received many FTTH application requirements To communicate with different types of FTTH users, we found that many users have misunderstandings about FTTH technology selection and application. These misunderstandings include ignoring the FTTH technical risks and blindly requiring full-service access; failing to understand the FTTH market characteristics in China, and blindly

[Abstract]: Modern communications to digital, broadband, intelligent, integrated development, the rapid development of digital technology has been CATV network, telephone network and data network closely linked to provide a variety of different types of information services, video on demand is one of them. This paper introduces the digital set-top box in VOD system, including the key technology, relevant standard and concrete realization method of STB

ARM JTAG Debugging principleOpen-jtag Development Group1 PrefaceThis article mainly introduces the basic principles of ARM JTAG debugging.The basic content includes the introduction of TAP (TEST ACCESS PORT) and Boundary-scan ARCHITECTURE,On this basis, combined with ARM7TDMI, the JTAG debugging principle is introduced in detail.This article is mainly summed up some of the previous period of experience, I hope to understand the ARM JTAG debugging user

effective method for measuring the MPEG-Ⅱ bit rate at the decoder or system layer multiplexing receiver. Use an MPEG decoder chip and an embedded processor to centrally manage the reference clock of the MPEG-Ⅱ Transfer Stream program. Because the reference clock of the MPEG-Ⅱ transmission stream program is set based on a certain encoder system's reference clock, the bit rate of the stream can be basically determined through real-time monitoring, at the same time, compare the reference clock of

I. Overview 1. Current status and progress of domestic CATV network Radio and television is the largest media in China, it provides radio and television broadcasting services from wireless to cable, has the largest number of information audiences, is the biggest advertising, economic, market, entertainment and cultural information collection, production, dissemination and provider. By 1999, CCTV and more than 20 provincial-level television stations

. Several optical access methods 2.1 Optical Fiber Distributed Network (FDN)FDN is divided into active and passive optical fiber networks.The difference between a passive optical fiber network and an active optical fiber network is that it replaces a remote Optical Fiber Device (ROLT) in an active optical fiber network with a pair of optical passive splitter ). the transmission protocols used by the two are also different. The active optical fiber network adopts PDH or SDH transmission protocols

" and "0" digital signals are transmitted using copper wires, the high voltage and low voltage statuses usually correspond to "1" and "0" respectively ". When the transmitted signal voltage is applied to the laser diode to convert it into a light signal, the light will generate or disappear. If the light-emitting and disappearing statuses are set to "1" and "0" respectively, digital data can be transmitted through optical fiber. If the optical signal transmitted from the optical fiber is restore
