Suspected white Lenovo ZUK edge exposure screen accounted for amazing

September 23, 2021

[IT168 information] recently frequent frequent high-profile dispensers Lenovo ZUK Edge exposure, although the new machine is called edge but not curved screen, but the proportion of high-screen design, before the release of the black rendering it seems that screen share Really high, the front of the fuselage is very narrow, now there are users released a white version of the Lenovo ZUK Edge spy photos, screen share is equally astonishing, but it is surprising that the white version of the screen is not so high.


From the spy photos exposed by users, the white Lenovo ZUK Edge also has a narrow border, but the chin part does not seem to be as narrow as the black version looks, similar to the Lenovo ZUK Z2 Pro, Home key is still rounded rectangle, should still be retained U-Touch interactive operation and fingerprint recognition function. The back of the fuselage is basically consistent with the Lenovo ZUK Z2 Pro, using arc design, from top to bottom are the camera, flash and laser focus module.

In terms of configuration, according to the previous news, Lenovo ZUK Edge uses a 5.5-inch 1080p screen, equipped with 2.35GHz Snapdragon 821 processor, 6 GB memory +64GB body storage, 13 million pixels rear and 8 million pixels front Camera, pre-installed Android 7.0.

FWDM - Filter Wavelength Division Multiplexer

Since the "optical telephone" device designed by Bell in 1880 was proved that light waves can transmit information, the era that truly brought optical communications came after the 1980s. A complete optical communication system should meet three conditions: light source, optical fiber, and photoelectric detection. In 1966, the United States borrowed from the Chinese Dr. Gao Kun to publish a thesis, pointing out that "quartz glass fiber is used to transmit optical signals for communication." In 1970, Corning Corporation of the United States successfully developed optical fiber, which provided an ideal transmission medium for optical communications. During this period, semiconductor lasers were also successfully developed, and light sources with wavelengths suitable for optical fiber low-loss transmission played a decisive role in optical fiber communications, all of which made the development of optical fiber communications extremely rapid.

Filter Wavelength Division Multiplexer (FWDM) is based on mature thin film filter technology. It has the characteristics of wide channel bandwidth, low insertion loss, high channel isolation, high environmental stability and reliability, and is widely used in single-mode optical fiber communications. System and DFA.

A key advantage of DWDM is that its protocol and transmission speed are irrelevant. The DWDM-based network can use IP, ATM, SONET/SDH, and Ethernet protocols to transmit data, and the processed data flow is between 100Mb/s and 2.5Gb/s. In this way, DWDM-based networks can transmit different types of data traffic at different speeds on a laser channel. From the point of view of QoS (Quality of Service), DWDM-based networks quickly respond to customer bandwidth requirements and protocol changes in a low-cost manner.
