According to Taiwan media reports, Asia-Pacific Telecom won the first open 5G experimental network in Taiwan by NCC Nuclear Power, and was the first operator among the five telecom operators in Taiwan to get the 5G experimental spectrum.
NBC Deputy Chairman and Spokesperson Weng Bozong said that in fact, the team consisting of the Institute of Industrial and Technological Research and the team formed by Hon Hai at the beginning of this year have applied for the 5G experimental spectrum.
Asia-Pacific Telecom said that unlike the 5G experimental spectrum obtained by the two groups mentioned above, the spectrum obtained by ITRI and Hon Hai is a closed site experimental network, that is, in a laboratory closed environment. The experimental network was carried out. As for the Asia-Pacific Telecom, the open experimental spectrum is an academic, educational, or telecom experimental network dedicated to network research and development.
Weng Baizong said that NCC is conducting nuclear 5G spectrum experiments in the 1870~1880MHz, 1775~1885MHz, and 3.4~3.5GHz frequency bands on the 24th of this month.
Asia-Pacific Telecom pointed out that this time, it was jointly submitted by Asia-Pacific Telecom, Hon Hai Technology Group and Jiaotong University. It plans to build a 5G experimental network in Neihu, Tucheng and Hsinchu Transportation University School District, and establish a 3GPP standard network structure. Through the experimental network verification, layout 5G services in advance, and related applications before the 5G.
At the beginning of this year, Pyeongchang Winter Olympics related real-time high-bandwidth service was realized through the pre-5G network. Asia-Pacific Telecom hopes to arrange 8K+5G, Internet of Things, artificial intelligence and robot ecosystem as soon as possible by arranging 5G ahead of schedule. Application, implementation of eight smart life applications.
In this 5G experimental network planning, Asia-Pacific Telecom will test the 1Gbps download speed and provide product verification for related service providers and network equipment vendors, hoping that the 5G products produced in Taiwan will be exported to the global market in advance.
Antenk DVI Series Digital Video Interface connectors are the standard digital interface for flat panels, video graphics cards, monitors and HDTV units. This series includes DVI-D (Digital), DVI-A (Analog) and DVI-I (Integrated Digital/Audio). Their unique crossing ground blades provide high speed performance at low cost. They are available in Straight or Right Angle PCB mount receptacles and mating male cable connectors. They support a data transfer rate of 4.95Gbps with a dielectric withstanding voltage of 500VAC. Each version features our specially designed contacts which improve signal performance and a zinc alloy shield that reduces electromagnetic interference (EMI).
Digital Visual Interface Cable Connectors
DVI ConnectorWith the advent of technologies such as DVD players, high-definition televisions, and even digital cable, the need for more advanced cables and connectors has increased. Digital Visual Interface (DVI) is one response to the growing need for interconnected systems, enabling digital systems to be connected to an array of displays. Yet DVI cables and connectors can also be complicated, and may lead to confusion between High Definition Multimedia Interface (HDMI) and DVI. Although the two systems have much in common, they service different niches of digital technology.
Digital Visual Interface
Older systems aren`t necessarily outdated systems. Although DVI preceded HDMI, it`s still widely used in both business and domestic settings. DVI connectors are designed to handle digital data transmission, incorporating three transmission channels in every connector link. The maximum bandwidth for data transfer is 165 megahertz, which is enough to relay up to 165 million pixels per second. Data is encoded for effective transfer, but a single link can handle around 4.95 gigabits per second of information. Double links can handle twice that amount.
Because a DVI cable carries information over a 165 megahertz bandwidth, complete digital resolution can be obtained. Using double link connectors increases the speed of transmission, but requires another cable. However, not many devices depend solely on a double link DVI, so this technolgy can be used on an as-desired basis.
Types of DVI Connectors
There are three general categories of DVI cable connectors: DVI-Digital (DVI-D), DVI-Integrated (DVI-I), and DVI-Analog (DVI-A). However, most connectors fall into one of the first two groups.
A standard DVI Connector is 37 mm wide and has 24 pins, 12 of which are used for a single link connection. When analog is involved, four additional pins are needed to support the additional lines of an analog signal. It is not possible to cross from a digital source to an analog display or vice versa. In those instances, an integrated connector is probably the best option. There are five common types of DVI connectors.
DVI-I Single Link
This kind of connector has three rows, each with six pins. There are two contacts. Because the connector is integrated, it can be used with both analog and digital applications.
DVI-I Dual Link
A DVI-I dual link connector can also be used with both digital and analog applications, but is configured with more pins to accommodate a dual connection. There are three rows with eight pins each, as well as two contacts.
DVI-D Single Link
Specifically designed for digital applications, a DVI-D single link connector has three rows of six pins, and looks much like a DVI-I single link connector. However, a DVI-D connector has no contacts.
DVI-D Dual Link
Also made specifically for digital applications, a DVI-D dual link features more pins (three rows of eight) for dual connections. Like a DVI-D single link, a DVI-D dual link connector has no contacts.
DVI-A
This particular type of connector can only be used for analog applications, and has three rows of pins. One row has five pins, one has four pins, and the last row has three pins. Like single link connectors, a DVI-A link connector has two contacts.
