Пре неколико дана, Силицон Лине и ГРЛ објавили су да је први светски активни кабл оптичких влакана који је прошао Ултра Хигх Спеед ХДМИ & рег; Сертификација (УХС програм) је завршила тестирање сертификата у лабораторији ГРЛ Таипеи. Овог пута, кабл је важан са оптичким модулима Силицон Лине ХДМИ 2.1 и активним каблом од оптичких влакана модел 300047; ова сертификација је од епохалног значаја; Силицон Лине ГмбХ технологија преноса оптичких влакана ултра мале снаге је светски лидер у потрошачким и комерцијалним апликацијама; и Граните Ривер Лабс (ГРЛ) су тест брзих сигнала и лидер решења је ГРЛХДМИ Forum authorized certification testing laboratory; this strong alliance is bound to set off an upsurge of ХДМИ2.1 AOC certification; the ХДМИ2.1 AOC era officially opens; Silicon Line and GRL announce the first certification that active ultra-high-speed ХДМИ® cable supports ХДМИ 2.1 function for long-distance transmission.
ТхеХДМИ 2.1 specification defines an ultra-high-speed ХДМИ cable (UHS Cable), which can support a bandwidth transmission speed of up to 48 Gigabits per second, and is designed to ensure the support of ХДМИ2.1 functions, including uncompressed 8K@60Hz and 4K@120Hz, If you want to achieve ХДМИ 2.1, you need to add power supply to drive signal transmission once it exceeds 3 meters. Pure copper wire is difficult to meet the demand after 5 meters. It needs to use active optical cable (AOC); it has equalization function when used inside the cable assembly The active circuit components are transmitted by optical fiber instead of copper wire. Therefore, AOC can overcome the limitations of traditional copper wire transmission, making the cable longer, thinner, and lighter, meeting the wiring needs of the living room, and achieving high-speed signal transmission and low electromagnetic interference makes high-speed ХДМИ signal transmission more stable. AOC meets the market's increasing demand for bandwidth, especially in the new generation of game consoles that require higher resolution and faster update rates.
Silicon Line CEO Ruud van der Linden said: "We are very pleased to have the first ХДМИ adopter’s AOC cable to obtain the Ultra High Speed ХДМИ Cable Certification. The AOC is an ХДМИ 2.1 module using Silicon Line. Silicon Line’s unique ultra-low power consumption module architecture, with internal chipset specially designed for ХДМИ UHS AOC and our innovative optical component (OSA) technology, using low power consumption without external power supply, and enabling cable suppliers to provide consumers affordable and certified ХДМИ UHS AOC; Rob Tobias, CEO of ХДМИ Licensing Administrator, Inc. mentioned: "The UHS program can bring a good user experience for ХДМИ adopters and consumers. We hope that active cables will be used in ХДМИ It will play an important role in the ecosystem and it will be an important part of the development of the UHS project.”
At the same time, Quintin Anderson, co-founder and chief operating officer of Granite River Labs, said: "Active ultra-high-speed ХДМИ® cables bring broad prospects to consumers, but they also bring unique design and test challenges. GRL is very happy to be here. Supporting Silicon Line for important achievements, we can be proud of ensuring the interoperability and downward compatibility of ХДМИ 2.1 products, as well as our role as the ХДМИФорум АТЦ.
At present, AOC cables generally use a 4-fiber core + 7 copper wire structure. 4 cores are used to transmit data. The 7 copper wires are used for power supply, one for CEC, and two for sound return (ARC). Root, a set of DDC signals (two core wires foamed and a ground wire shielded with aluminum foil) are used for the communication protocol. It is precisely because there is no standard to follow before, the wire materials on the market are very different, and the performance of the extracted wires is very different. Large, the fiber cores are OM1.5, OM2, OM2+, OM3, OM4, and the fiber cores are protected by PVC and Teflon, and the fillers are Kevlar, nylon, PP yarn, cotton, etc. The materials and outer covers are made of PVC, CL2PVC, TPE, CMP and other outer covers. The combination of different material options makes the cost of AOC wire very different, and the unit price span is also very different. With the association's definition of the specification and with the authorization of certification, optical ХДМИ will also enter the rapid development zone, and most consumer optical communications follow the development of optical communications in data centers. It is believed that pure optical ХДМИ will have a broader prospect than hybrid ХДМИубудуће.
