\n
OPTAV OV11HH-1FO-SA Lossless 4K HDMI 2.0 over Fiber Extender delivers zero-compression 4K UHD video over single LC single-mode fiber. Meanwhile, this black metal transceiver adopts six-wavelength CWDM DFB laser architecture to integrate video, analog audio and serial control onto one fiber strand. In turn, it runs full 18Gbps bandwidth with zero frame delay, native HDR and Dolby Vision for professional visual workflows. Besides, stable 700-meter single-mode transmission supports cross-building and large venue long-distance AV wiring. Therefore, this Lossless 4K HDMI 2.0 over Fiber Extender fits post-production studios, broadcast control rooms and museum digital walls perfectly. Furthermore, combined analog audio and bidirectional RS232 pass-through eliminates extra auxiliary cabling for integrated system deployment.<\/div>\n<\/div>\n
\n

Core Advantages of Lossless 4K HDMI 2.0 over Fiber Extender<\/h2>\n<\/div>\n
\n

1. Six-Wavelength CWDM Single-Fiber DFB Laser Architecture<\/h3>\n<\/div>\n
\n
First of all, this Lossless 4K HDMI 2.0 over Fiber Extender embeds six independent DFB laser channels inside each TX\/RX unit. Specifically, four 6Gbps optical lanes (1270\/1290\/1310\/1330nm carry lossless HDMI TMDS video signals. Next, two 1.25Gbps auxiliary wavelengths (1490\/1550nm transmit bidirectional EDID, HDCP, RS232 and analog audio data. To be precise, only one simplex LC single-mode fiber handles all video, audio and control streams without extra fiber pairs. On top of that, wavelength division multiplexing completely avoids signal cross-talk between UHD video and auxiliary data. As a result, AV integrators drastically cut fiber quantity and tidy crowded equipment racks. Importantly, the all-in-one optical design removes fiber splitters and repeaters for medium-long distance layouts. For this reason, it reduces overall project cabling and labor costs significantly.<\/div>\n<\/div>\n
\n

2. Lossless 18Gbps 4K@60Hz 4:4:4 & Full HDR Compatibility<\/h3>\n<\/div>\n
\n
When it comes to lossless video performance, this extender fully complies with HDMI 2.0 and transparent HDCP 2.2\/1.4 pass-through. Correspondingly, it transmits uncompressed 18Gbps bandwidth without pixel reduction or color compression. Even better, it supports native 4096\u00d72160@60Hz YUV4:4:4 deep-color UHD video streams. Meanwhile, complete HDR and Dolby Vision metadata transfers intact across the full 700-meter fiber path. In effect, long single-mode fiber runs never create frame lag, screen flicker or color deviation on remote displays. In turn, colorists and venue audiences view identical pristine lossless 4K visuals far from source PCs and media players.<\/div>\n<\/div>\n
\n

3. 700M LC Single-Mode Fiber Stable Long-Distance Transmission<\/h3>\n<\/div>\n
\n
In terms of optical transmission capacity, this unit exclusively matches standard simplex LC single-mode fiber cables. Correspondingly, built-in CWDM DFB lasers maintain steady light power to achieve reliable 700-meter lossless extension. Even better, compact LC connectors fit global standard single-mode patch cords used in broadcast and commercial AV engineering. Meanwhile, fiber medium fully isolates EMI and RFI noise from industrial power and lighting circuits. In effect, cross-floor and cross-building venue layouts skip costly signal amplifiers and equalizers. In turn, teams build clean, scalable permanent fiber signal chains for large-scale exhibition and broadcast projects.<\/div>\n<\/div>\n
\n

4. Bidirectional RS232 + Independent Analog Audio Pass-Through<\/h3>\n<\/div>\n
\n
In terms of multi-signal integration, the auxiliary CWDM wavelengths carry dual types of auxiliary signals simultaneously. Correspondingly, transparent bidirectional RS232 enables remote equipment configuration and system debugging from the receiver side. Even better, one-channel analog audio transmits separately alongside digital HDMI audio for extra speaker or monitoring outputs. Meanwhile, all control and analog audio signals share the same single fiber without occupying video bandwidth. In effect, one fiber cable completes lossless 4K video, digital surround sound, analog audio and serial control transmission at once. Thereby, field technicians eliminate separate control and audio wiring during venue construction and renovation.<\/div>\n<\/div>\n
\n

5. Uniform Metal Housing & Wide Stable Operating Envelope<\/h3>\n<\/div>\n
\n
Last but not least, this Lossless 4K HDMI 2.0 over Fiber Extender features identical black metal TX\/RX enclosures sized 162\u00d785\u00d726mm. Moreover, each module consumes only 3W power via standard 12V\/2A DC adapters. For starters, solid metal construction boosts heat dissipation and electromagnetic shielding for 24\/7 continuous studio operation. Equally, it operates reliably between -10\u00b0C and 60\u00b0C and withstands storage temperatures ranging from -40\u00b0C to 85\u00b0C. Additionally, matching mounting brackets support secure rack or wall fixed installation. Consequently, operators skip extra cooling and surge protection accessories for long-term broadcast and exhibition equipment rooms.<\/div>\n
