The fiber access how to develop copper wire ultra-wideband network construction reproduction boom
2013年5月3日Affected by 2012 London Olympic Games driver and digital the incentive of the policy in Great Britain, British Telecom is an earlier carried out the operators of the next generation of ultra-wideband network construction. In 2008, they first choose Ebbs fleet new district of east London FTTH trial bureaus, then two innings in west London and Wales points cloth more than one hundred outdoor cabinets for FTTC VDSL2 trial bureaus, after the return on investment, construction cycle, the user bandwidth comprehensive comparison and analysis, finally decided to adopt FTTC Fiber Optic Adapter for ultra broadband network development. From the second half of the year of 2009 began to deploy the beginning of to the 2013, After multi-3 years of time, already is cloth to put more than thirty-five thousand units outdoor cabinets, to achieve thirteen million of families, a user to override the of the 50% of the accounting for about the United Kingdom, the monthly new increase payment of VDSL2 terminal more than hundreds of thousands of Taiwan, plans to in 2014 to achieve seventeen million families to, a user to override the of the two-thirds of the accounting for about the United Kingdom.
The BT FTTC-based broadband products 40M and 80M of two FTTC products based on FTTH Fiber Optic Patch Cord on Demand product, the bandwidth of 100M and 300M, but most users still choose the higher cost of construction FTTC also introduced.
VDSL2 with ADSL2 + same DMT modulation technology, can be backward compatible with ADSL2 +, and work within the 2.2 MHz band of ADSL2 + technology, compared to VDSL2 can work with to 17 MHz even 30 MHz band, divided more muck channel up and down, in a short distance can provide higher fiber optic converter, so the ADSL2 + technology usually locate on board the DSLAM equipment, and VDSL2 suitable for distance shorter FTTC outdoor cabinets or FTTB corridor solution.
With the gradual increase of the global broadband speed and VDSL2 standard mature and stable product, VDSL2 shipments every year.
