UGREEN HD178 HDMI 4K Fiber Optic Male Cable 25M

The UGREEN HD178 25M Fiber Optic HDMI Cable is designed for installations that require HDMI transmission over a much longer distance than a standard HDMI cable.

At 25 metres, maintaining a stable high-resolution signal can become challenging with conventional passive copper HDMI cables. The HD178 addresses this by using optical fiber to carry high-speed signals over the long cable run. This makes it particularly suitable for professional installations where the source equipment is located far from the display.

4K Ultra HD Support

The UGREEN HD178 supports 4K Ultra HD video, providing detailed images when connected to compatible HDMI source and display devices. It is suitable for applications including business presentations, CCTV monitoring, movies, digital signage, classroom projection and large screen displays.

The actual resolution and refresh rate available will depend on the connected equipment and the specific HD178 hardware specification.

25 Metre Long Distance HDMI

With its 25-metre length, this cable provides plenty of flexibility for larger rooms and installations. For example: NVR → UGREEN HD178 25M → CCTV Monitor or Laptop/PC → UGREEN HD178 25M → Projector. This allows equipment to remain in a server rack, control room or presentation area while the display sits elsewhere.

Fiber Optic Transmission

The HD178 uses optical fiber technology to transmit high-speed HDMI signals over its long cable run. Fiber technology provides several advantages for long-distance installations. It helps maintain signal stability while also reducing susceptibility to electromagnetic interference (EMI). This makes the cable useful in offices, server rooms, conference halls and other environments containing electrical and networking equipment.

HDMI Male to Male

The cable features an HDMI male connector at both ends, allowing direct connection between compatible HDMI equipment. Typical installation: HDMI Source → HD178 → HDMI Display

Compatible equipment may include PCs, laptops, NVRs, DVRs, media players and other HDMI source devices connected to TVs, monitors, projectors or commercial displays.

Aluminum Shell Connectors

The HDMI connectors feature aluminum shells, providing a durable exterior around the connector assembly. This design is suitable for both home and professional installations where a reliable long-distance connection is required.

Directional HDMI Cable

An important consideration with fiber-optic HDMI cables is that they are normally directional. The cable has a source side and display side: SOURCE → DISPLAY. The SOURCE end connects to the transmitting device, such as an NVR, PC or media player. The DISPLAY end connects to the TV, monitor or projector. Always check these markings before routing the 25m cable through a wall, ceiling or conduit.

Technical Specifications

Ideal for CCTV Installations

The 25M HD178 is particularly useful when an NVR or DVR is installed inside a secure server room or rack, while the monitoring screen is located elsewhere. A typical connection would be: NVR HDMI Output → HD178 25M → Monitoring TV.  This allows the recorder to remain secure while still providing a direct HDMI display at another location.

Ideal for Projectors

The cable is also suitable for ceiling-mounted projectors in classrooms, boardrooms and conference halls. You can run the 25m fiber HDMI cable from the presentation area to the projector without relying on a wireless connection.

Installation Advice

Because the HD178 contains optical fibers, avoid sharp bends, crushing, excessive pulling or twisting during installation. More importantly, test the cable before installing it permanently. Confirm the SOURCE and DISPLAY ends before pulling it through conduit or closing ceilings.
