4K@30Hz HDMI Fiber Optic Extender - 20km Single-Mode SFP Transmission ( Model: HDES51)
This is an industrial-grade fiber optic extender with a pure hardware design, requiring no software or drivers. It complies with the SFP MSA and SFF-8472 standards, supports a resolution of 4K30Hz, and can extend distances up to 20KM. Suitable for professional settings including broadcast production, integrated conference systems, and HD surveillance applications.
Key Features & Business Benefits
20km Ultra-Long Distance Transmission: Utilizes standard SFP optical modules and single-mode fiber with bidirectional LC interface, achieving stable 4K@30Hz 4:4:4 signal extension up to 20km without degradation or repeaters.
Premium Video & HDR Support: Full support for HDMI 4K@30Hz with 4:4:4 chroma sampling and HDR (HDR10/HDR10+/Dolby Vision/HLG), ensuring broadcast-quality output for professional environments.
Independent Audio Extraction: Dedicated 3.5mm stereo output alongside embedded 7.1 channel audio pass-through (DTS-HD, Dolby TrueHD, ATMOS, etc.), providing flexible integration for conference systems and surveillance monitoring.
Cost-Efficient Infrastructure: Single-fiber bidirectional transmission significantly reduces cabling costs and complexity compared to dual-fiber or CATx solutions while maintaining superior EMI immunity.

Product Application Fields
4K@30Hz HDMI Fiber Optic Extender for Broadcast Production Studios
In live broadcast production and multi-camera studios, traditional copper cables suffer severe signal degradation beyond 100 meters, causing color banding, dropouts and costly re-shoots. Our industrial-grade 4K@30Hz HDMI Fiber Optic Extender delivers pure 4:4:4 HDR signals over single-mode fiber up to 20 km with zero latency and full EMI immunity-ideal for remote production trucks, outdoor OB vans and multi-building facilities. Procurement managers and system engineers can request small-batch sampling, custom SFP module pairing or OEM-labeled housings.
HDMI Fiber Optic Extender for Integrated Conference Systems Across Buildings
Large campuses and multi-site conference centers often struggle with long-distance HDMI distribution: copper solutions require expensive repeaters, introduce interference and limit audio flexibility. This pure-hardware extender transmits 4K@30Hz video plus independent 3.5 mm audio extraction and 7.1-channel pass-through over a single bidirectional LC fiber, simplifying cabling while maintaining broadcast-quality picture. Engineers benefit from one-on-one technical selection support and custom firmware-free configurations.
Industrial HDMI Fiber Optic Extender for HD Surveillance Monitoring Networks
City-wide or campus HD surveillance systems demand ultra-long, interference-free video backhaul that copper or wireless links cannot reliably provide. Our 20 km single-mode SFP extender maintains stable 4K@30Hz monitoring feeds even in high-EMI industrial environments, eliminating the need for intermediate amplifiers. Security integrators and procurement teams can order customized port configurations, private labeling or OEM assembly for volume projects.
FAQ
Q: What fiber type is required for 20km transmission?
A: Single-mode fiber with LC connectors. The unit uses standard SFP modules operating at 1310nm/1550nm wavelengths for reliable bidirectional communication.
Q: Does this extender support HDCP 2.2 or 4K@60Hz?
A: This model is optimized for stable 4K@30Hz with HDCP 1.4. For higher bandwidth requirements, please contact our team for alternative solutions in our 4K@60Hz series.
Q: Is the audio de-embedded output independent of the HDMI output?
A: Yes. The 3.5mm stereo output provides clean audio separation while the HDMI output continues to carry full embedded multi-channel audio.
Q: Are these units compatible with third-party SFP modules?
A: The design follows SFP MSA standards. While we recommend our matched modules for guaranteed performance, compatible MSA-compliant SFPs can be used.
