The VDSL2 Splitters of V1.1.1 standards.
Background technology
VDSL2 technologies support voice, video, data, HDTV to original ADSL technologies, VDSL2 has progressively been substituted at present
It is triple with interactive game etc.（triple-play）The widespread deployment of business, may help to user and operator progressively, flexibly and
Cost-effectively upgrade existing xDSL architectures.Present xDSL access technologies are still central office (CO）Between user
Communication performance bottleneck.Central office and distal end DSLAM (Digital Subscriber Line Access Multiplexers）Gigabit Ethernet link can be provided even
The technology of more speed, user side are 54Mbps and 100Mbps wired and WLAN (LAN/WLAN）.But this two
Link between person either has rate limit with ADSL, ADSL2/2+ or VDSL.In addition, passed simultaneously on same medium
Defeated video/HDTV, data and " triple " business as voice need perfect service quality more ripe than VDSL1 or ADSL
（QoS）.Newest triple play service includes at least three television channel, several VoIP connections and sufficiently fast internet access,
It is required that data rate at least to reach 30 ~ 40Mbps, this speed is about ADSL2+ solutions in actual motion state
Two times of the speed that can reach down.In order to overcome the shortcomings of existing access technology, VDSL2 is developed and had standardized in good time to industry
Technology.VDSL2 is to eliminate last mile of bottleneck and the global preferable xDSL technologies for largely disposing advanced triple play service.
European telecommunication alliance has issued the 952-3 V1.1.1 standards of ETSI TS 101, standard definition in 2 months 2012
The new specifications parameter requirement of VDSL2 Splitters, new standard not only has more harsh to frequency of fadings and pad value
It is required that and also need to meet simultaneously in a telephone line regulation of 4 identical filter circuits in parallel, therefore, to meet
The standard, the filter circuit that many Splitter manufacturers are formed using the double winding inductance and electric capacity of 4 or more exponent numbers, together
When to meet the regulation of 4 identical filter circuits in parallel, employ expensive triode current control circuit etc. so that member
Device cost and manufacturing cost substantially increase relative to ADSL Splitters, thus cause customer using cost to rise, and lose
The market competitiveness.
