Which HDMI cable to choose?
Three situations, three solutions. Identify your need in 30 seconds.
Distance > 5 metres
Fibre optic HDMI cable
You need to connect a source (PC, console, Blu-ray player) to a screen or projector that is 10 to 100 metres away. The fibre optic HDMI cable is the cleanest solution: a single thin cable, no box, perfect signal.
- Living room home cinema → TV or video projector
- Photo/video studio → long-distance monitoring
- Conference room → presentation screen
- Fixed installation flush-mounted in walls
Long-range KVM extension
HDMI extender over network
You want to extend an HDMI and USB signal over an existing Ethernet or fibre network — ideal for training rooms, auditoriums or remote workstations where the computer stays in the server room.
- Workstation remote setup (PC in rack)
- Training room with remote teacher workstation
- Auditorium: source in control room → stage
- Remote control over IP network
Simple connection
Female-to-female HDMI adapter
You need to connect two HDMI cables together or change the orientation of a connector. The female-to-female HDMI 2.1 adapter maintains 8K/4K support and preserves the full bandwidth.
- Extend an existing HDMI cable
- Connection behind a TV unit
- HDMI patch panel in fixed installations
- Change cable direction
Quick decision matrix
- Gaming PC → 8K TV at 15m → Fibre optic HDMI cable
- PS5 → projector at 20m → Fibre optic HDMI cable
- Computer in rack → screen at 50m → KVM HDMI extender
- Two cables to connect → Female-to-female adapter
- Home cinema flush-mounted in walls → Fibre HDMI cable (flexible, thin)
- Conference room, existing RJ45 cable → HDMI extender over Ethernet

Why choose a fibre optic HDMI cable?
The limits of copper HDMI cable
- Degradation beyond 5–10 m: passive copper HDMI cables lose quality and can lose the signal entirely beyond 10 metres in 4K. In 8K, this limit drops to 3–5 metres.
- Rigid and heavy cable: high-performance copper cables are thick and difficult to thread through conduits or walls.
- Sensitive to electromagnetic interference: in environments with a lot of electrical equipment (studios, server rooms), copper cables pick up noise.
- Amplifiers required: long-distance copper solutions require amplifier boxes that add latency and points of failure.

The advantages of fibre optic HDMI
- Transmission up to 100 m without loss: OM3 fibre optic carries the light signal without attenuation over long distances — identical signal at 5 cm or 100 metres.
- 8K@60Hz and 4K@120Hz support: 48 Gbps bandwidth in accordance with the HDMI 2.1 specification — the future of video content is covered.
- Thin and flexible cable: the fibre cable is much thinner and lighter than amplified copper HDMI cables — easy to flush-mount in walls or run through 20 mm conduits.
- Immunity to interference: fibre optic is insensitive to electromagnetic fields — ideal in technical or industrial environments.
- VRR, ALLM, eARC, HDR: all advanced HDMI 2.1 functions are supported — variable refresh rate, low latency mode, audio return.
Recommended use cases
- High-end home cinema: 8K TV or 4K video projector more than 5 metres from the source
- Gaming PC: RTX 4090 / RX 7900 graphics card to 4K@120Hz monitor or TV
- Flush wall installation: cable run through walls during construction or renovation
- Conference room: laptop → screen or video projector at 15–30 metres
- Photo/video studio: editing computer → reference monitor on another workstation
- Auditorium / performance hall: technical control room → stage screens
- Digital signage: content player → wall or window display screens
- Simulations and training: PC in server room → remote operator stations

What you gain compared to copper cable
+90 m range
Up to 100 m without amplifier box, vs 5–10 m max in copper for 8K.
Cable 3× lighter
The OM3 fibre cable is thin (4.5 mm) and flexible — easily fits in mouldings and conduits.
Zero added latency
Unlike active extenders, the fibre HDMI cable adds no processing latency.
FAQ — Fibre optic HDMI cable
1What's the difference between a fibre optic HDMI cable and a copper HDMI cable?
A copper HDMI cable transmits the signal electrically — it is limited to 5–10 metres in 4K and 3–5 metres in 8K before degradation. A fibre optic HDMI cable converts the signal into light, transmits it through OM3 fibre, then reconverts it at the other end. Result: up to 100 metres without loss, without external amplifier, with the same signal as if the source were 50 cm from the screen.
2Does a fibre optic HDMI cable require external power?
No. The Elfcam HDMI 2.1 fibre optic cable is powered by the HDMI bus — the 5 V supplied by the HDMI port of your source (PC, console, player) is enough to power the opto-electronic converters built into the connectors. No mains adapter, no USB power cable required. Note: the cable is directional — the "Source" end must be plugged in on the source side.
3Does the fibre optic HDMI cable support VRR for gaming?
Yes. Our HDMI 2.1 fibre optic cable supports all the advanced gaming features of the HDMI 2.1 specification:
- VRR (Variable Refresh Rate) — adaptive synchronisation between GPU and screen
- ALLM (Auto Low Latency Mode) — automatic activation of game mode on the TV
- QFT (Quick Frame Transport) — display latency reduction
- 4K@120Hz with Dynamic HDR — for PS5 and Xbox Series X
4Is the cable compatible with my AV receiver (home cinema)?
Yes, provided your AV receiver has HDMI 2.1 ports. Recent AV receivers (Denon, Yamaha, Marantz, Onkyo) with HDMI 2.1 support eARC (Enhanced Audio Return Channel) — our cable supports it too. If your receiver is HDMI 2.0, the cable will work but will be limited to HDMI 2.0 capabilities (4K@60Hz max).
5Can this cable be run through a wall or conduit?
Yes. This is one of the major advantages of the fibre HDMI cable: it measures 4.5 mm in diameter versus 8–10 mm for an amplified long-distance copper HDMI cable. It is flexible and easily passes through 20 mm conduits, wall mouldings or flush-mounted cable runs. Note: the standard HDMI connectors at each end require a minimum opening of 15 mm wide to pass through — provide a pass-through tube or detachable connectors for flush-mounted installations.
6What length of fibre optic HDMI cable do I need?
Measure the actual distance by following the cable path (not the straight-line distance), adding bypasses around obstacles, then add 10 to 15% margin. Example: source 12 m from the screen with a bend around a wall → plan for 15 m. Our cables are available from 10 m to 100 m. When in doubt, choose the longer length — a slightly too long cable is always manageable, a too short cable forces you to start over.
7What's the difference between a fibre HDMI cable and an HDMI extender over Ethernet?
- Fibre optic HDMI cable: a single cable from point A to point B. No active box. No added latency. Ideal for fixed installations where both points are close to the cable.
- HDMI extender over Ethernet: a transmitter and receiver connected by Cat 6/7 cable or via an existing IP network. Allows you to use the network infrastructure already in place. May add 1–5 ms of processing latency. Ideal for workstation remote setups or installations where network cabling is already present.
