AV transmitter & receiver SCP 998-DO-EXT — wired AV extender, USB-powered, supports DTS and PCM, PVC housing

SCP 998-DO-EXT is a wired AV transmitter and receiver kit that converts HDMI Type A connections to a fiber MPO link using two detachable dongle adapters. The kit is USB-powered, housed in PVC enclosures, and is designed to extend high-bandwidth audiovisual signals over optical fiber for home or professional AV installations. It supports high-resolution video and common HDMI features while keeping the physical connection compact and flexible.

Advantages

The kit provides a thin, lightweight and flexible fiber link that reduces bulk compared with traditional copper cables. Its detachable dongle design simplifies installation and future upgrades, and USB power increases compatibility with a variety of power sources. The solution supports current HDMI features such as HDR, EDID management, CEC control and HDCP2.3 for content protection.

Suitable for

• Extending HDMI signals between source and display where long runs are required
• Home theatre and professional AV installations
• Setups that require support for 8K@60 (4:2:0) and multi-channel audio
• Environments where a thin, flexible cable route is preferred

When it may not be suitable

This kit requires an external EasyFiber patch cable (sold separately) with MPO connectors; it is not a complete end-to-end solution without that fiber cable. It also relies on USB power — in environments where USB power is unavailable or where integrated PoE or mains-powered extenders are preferred, this product may not meet requirements.

Key specifications

• Video bandwidth: up to 48 Gbps
• Maximum resolution support: up to 8K (7680 × 4320) at 60 Hz with 4:2:0 chroma subsampling
• HDMI features: Dynamic HDR, EDID pass-through, CEC control, e-ARC support, HDCP 2.3
• Audio formats: DTS and PCM support
• Connectors: HDMI Type A (male) to MPO (female) dongle adapters (two pieces: TX and RX)
• Power: USB-powered, typical consumption 0.7 W per unit
• Housing: PVC enclosure
• Design: Detachable dongle adapters; lightweight and flexible fiber link

How to use

Attach the HDMI Type A dongle to the source and the HDMI Type A dongle for the display to the sink device, connect the two MPO ports using a compatible EasyFiber MPO patch cable (sold separately), and supply USB power to each unit using the included USB power cables. The system is plug-and-play; once power and fiber are connected the extender transmits HDMI video and audio over the optical link. Follow display and source settings for resolution and audio format selection if necessary.

What to consider before purchase

• EasyFiber MPO patch cable is required but sold separately
• USB power must be available at both transmitter and receiver locations
• Supports 8K@60 only with 4:2:0 chroma — verify display and source compatibility
• Designed for wired optical connections; not suitable where no fiber routing is possible

Usage recommendations

For reliable operation, use a compatible MPO optical patch cable from the same product family, ensure firm USB power connections, and confirm source/display HDMI settings match the desired resolution and audio format. Keep fiber connectors clean and protected when installing or storing.
