The DTECH DT-HF8020K is a 20-meter HDMI 2.1 armored active optical cable for connecting compatible HDMI sources to TVs, monitors and projectors. Supporting 8K@60Hz, 4K@120Hz and up to 48Gbps bandwidth, it provides high-resolution video and digital audio transmission over an extended distance.
Its hybrid fiber optic construction, reinforced metal armor and advanced HDMI features make it suitable for home theaters, gaming systems, conference rooms and professional AV installations. Explore the DTECH DT-HF8020K price in Bangladesh at IT Source.
The DTECH DT-HF8020K is an armored HDMI 2.1 active optical cable designed to connect compatible HDMI source devices and displays across a 20-meter distance. It uses integrated photoelectric conversion technology to transmit high-bandwidth HDMI signals through a hybrid optical fiber and copper structure.
The cable supports 8K resolution at 60Hz, 4K at 120Hz and manufacturer-listed 4K at 144Hz, alongside Dynamic HDR, Dolby Vision, eARC and supported gaming functions. Its 48Gbps bandwidth accommodates compatible high-resolution video and multichannel digital audio formats.
Reinforced metal armor surrounds the cable structure to provide added protection against installation stress and electromagnetic interference. Durable zinc-alloy connector housings and gold-plated HDMI contacts complete its construction.
The DT-HF8020K supports video resolutions up to 7680×4320 at 60Hz and 3840×2160 at 120Hz. DTECH also lists 4K@144Hz operation, providing flexibility for compatible high-resolution monitors, televisions and gaming equipment.
Actual resolution and refresh rate depend on the connected source, display, graphics hardware and video format. The cable carries supported HDMI signals but cannot add higher-resolution capabilities to incompatible equipment.
The DT-HF8020K uses HDMI 2.1 active optical technology with a manufacturer-specified bandwidth of up to 48Gbps. Integrated photoelectric conversion enables high-bandwidth digital audio and video signals to travel through the 20-meter cable.
This design is practical for installations where source equipment is positioned away from a projector or display. The active optical structure also helps reduce interference associated with conventional electrical signal transmission over longer cable runs.
The cable uses a metal-armored hybrid structure containing four optical fibers and seven copper conductors. The reinforced armor improves protection against pressure, pulling and installation-related stress while helping shield the signal path from electromagnetic interference.
Zinc-alloy connector housings provide durable protection around the HDMI connections. Although the cable is armored, installers should still avoid excessive force, crushing and sharp bends that may damage its internal components.
The manufacturer lists Dynamic HDR, Dolby Vision, 3D video and HDCP 2.2/2.3 compatibility for the DT-HF8020K. These features support compatible high-resolution multimedia content and protected digital video transmission.
HDR presentation and content protection depend on the connected source, display and supported media. The cable passes compatible HDMI signals rather than independently processing or upgrading the picture quality.
The DT-HF8020K supports eARC and DTS:X for compatible home theater and audio systems. It also supports HDMI gaming features including Variable Refresh Rate, Auto Low Latency Mode, Quick Frame Transport and Quick Media Switching.
These functions are useful for supported gaming consoles, PCs, TVs and AV receivers. The connected devices must support the relevant HDMI features, and some functions may require configuration in the source or display settings.
The 20-meter cable length provides practical reach for projector installations, wall-mounted televisions, conference rooms and large multimedia spaces. Its HDMI male-to-male connectors allow direct connection between compatible source and display equipment.
As an active optical HDMI cable, the DT-HF8020K has a defined signal direction. Connect the source-marked end to the HDMI output device and the display-marked end to the receiving screen, checking both ends before permanent installation.
Home Theater Users: Connect media players and AV equipment to distant displays. Gamers: Use compatible high-refresh-rate HDMI monitors and TVs. AV Installers: Route HDMI connections across 20-meter installations. Conference Rooms: Connect presentation equipment to projectors. Digital Signage Operators: Install compatible high-resolution commercial displays.
