Laser Focus World is an industry bedrock—first published in 1965 and still going strong. We publish original articles about cutting-edge advances in lasers, optics, photonics, sensors, and quantum technologies, as well as test and measurement, and the shift currently underway to usher in the photonic integrated circuits, optical interconnects, and copackaged electronics and photonics to deliver the speed and efficiency essential for data centers of the future.

Our 80,000 qualified print subscribers—and 130,000 12-month engaged online audience—trust us to dive in and provide original journalism you won’t find elsewhere covering key emerging areas such as laser-driven inertial confinement fusion, lasers in space, integrated photonics, chipscale lasers, LiDAR, metasurfaces, high-energy laser weaponry, photonic crystals, and quantum computing/sensors/communications. We cover the innovations driving these markets.

Laser Focus World is part of Endeavor Business Media, a division of EndeavorB2B.

VDSL2: Long distance two-core transmission solution

VDSL (Very high-speed Digital Subscriber Line, ITU-T G.993.1), was first published in 1991 and standard approved by the International Telecommunication Union (ITU) in November 2001. It is digital subscriber line (DSL) technologies providing data transmission faster than Asymmetric Digital Subscriber Line (ADSL).

VDSL offers speeds of up to 52 Mbit/s downstream and 16 Mbit/s upstream, over a single flat untwisted or twisted pair of copper wires using the frequency band from 25 kHz to 12 MHz. VDSL2 is an enhancement of VDSL, which was standardized in ITU-T G.933.2. VDSL2 use frequencies of up to 30 MHz to provide data rates exceeding 100 Mbit/s simultaneously in both the upstream and downstream directions. The VDSL2 is capable to support wide deployment of triple play services includes voice, video, data and general Internet access.

VDSL21

Wondertek Technology can provide VDSL2 products WD-V101-G and Alternative G.hn standard products WD-E2000M-G. The system is very complete and can be selected according to customer needs.WD-V101-G technology solves the problem of medium-distance high-speed transmission, and uses traditional two-core wires to meet the needs of industrial field high-speed networks.For example: video monitoring, data acquisition, equipment control, etc. WD-V101-G is divided into CO and CPE to achieve point-to-point dedicated line solutions, which are widely used in coal mines, factories, railways and other long-distance network transmission.
