UGREEN HD178 HDMI Fiber Optic Cable 25M carries 4K UHD video at 60Hz across 18Gbps of HDMI 2.0 bandwidth, and it sells for KSh 6,000 at Mascom International, Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. This is UGREEN SKU 45506, a brand new and sealed active optical cable that turns your video into light instead of pushing it down copper wire. The UGREEN HD178 uses gold-plated contacts inside aluminum alloy housings at both ends. It passes HDCP 2.2, HDR10, and 48-bit color depth intact. Every UGREEN HD178 unit in stock ships with our countrywide delivery.
Twenty-five metres is the distance where ordinary copper HDMI gives up. Church AV teams across Nairobi, lecture halls at Kenyatta University and JKUAT, conference rooms in Upper Hill, and hotel banquet spaces in Diani all hit the same wall: the projector hangs from the ceiling, the laptop sits on a podium, and the picture flickers or quietly drops to 1080p somewhere in between. The UGREEN HD178 fixes that by carrying the image as light through a hybrid glass and copper core. Signal strength at the far end matches signal strength at the source, so 4K arrives as 4K.
Unlike other electronics retailers in Kenya who stock unbranded 25-metre leads with no published specification, Mascom International sells the UGREEN HD178 with its numbers on record: 18Gbps, HDCP 2.2, 24-bit/192kHz audio, EMI and RFI resistance. Installers who fit boardrooms and worship venues consistently report that optical runs survive being pulled through conduit beside mains power cabling, where copper HDMI picks up noise. Walk into our Kimathi Street shop Monday to Saturday between 9:00 AM and 7:00 PM to see the UGREEN HD178 spool before you buy, or order it for pay-on-arrival delivery anywhere in Kenya.
Common Questions About the UGREEN HD178 HDMI Fiber Optic Cable 25M
Why does a 25-metre HDMI run need fiber instead of copper?
Copper HDMI starts shedding 4K signal strength past roughly 10 metres, which is why long copper leads flicker, sparkle, or fall back to 1080p. The UGREEN HD178 converts the picture into light at the source end and back into an electrical signal at the display end. Light does not weaken across 25 metres the way current does. The far end of the run shows the same 4K 60Hz image the laptop sent out.
Does the UGREEN HD178 really hold 4K at 60Hz across the full length?
Yes. The full 18Gbps of HDMI 2.0 bandwidth travels all 25 metres, which is exactly what 3840 x 2160 at 60 frames per second demands. You also keep HDCP 2.2, HDR10, and 4:4:4 color sampling, so spreadsheet text and slide headings stay readable rather than smearing. Your source device and your display both need to handle 4K 60Hz themselves. A 1080p projector still shows 1080p; the cable carries what it is given.
Which end goes into the laptop and which goes into the projector?
The connector printed Source plugs into the device sending the picture: laptop, PlayStation, decoder, or media player. The connector printed Display plugs into the projector, TV, monitor, or video wall. This cable runs one direction only, because the light conversion happens in one direction. Plug it in backwards and the screen stays blank, which people often mistake for a faulty cable. Check the printed labels before pulling anything through conduit.
Does the UGREEN HD178 need a power adapter or a signal booster?
No. It draws its small operating current straight from the HDMI ports, and that draw is low enough that laptops, decoders, and consoles supply it without complaint. There is no plug pack, no USB power lead, and no repeater box sitting mid-run. That matters in a boardroom ceiling or a church rafter, where a powered extender would need a socket nearby and would become one more component that can fail.
Will it work with a PS5, Xbox Series X, or Apple TV?
Yes, all three connect and output up to 4K at 60Hz through this cable. The ceiling is HDMI 2.0, so PlayStation 5 and Xbox Series X will not reach their 4K 120Hz modes here; that needs HDMI 2.1 at 48Gbps. For big-screen viewing, church projection, presentations, and 4K 60Hz gaming across a long room, the UGREEN HD178 covers it. Gamers chasing 120Hz should ask us about UGREEN's 8K HD183 range instead.
Does it carry Dolby Atmos and DTS:X to my AV receiver?
Yes. The cable passes Dolby Atmos, DTS:X, Dolby TrueHD, DTS-HD Master Audio, AC-3, and standard LPCM at up to 24-bit/192kHz. Audio and video stay locked together across all 25 metres, so speech matches lips on a stage screen. Connect the Source end to your Blu-ray player or media box and the Display end to the receiver. Your receiver decides which of those formats it can actually decode.
Can the cable be pulled through conduit or a ceiling void?
Yes, and it is easier than copper because it is thinner and far lighter. Two cautions apply. Pull by the aluminum connector housing rather than the cable body, and never kink it tightly, because glass fiber cracks where copper simply bends. Leave a gentle loop at each end. Installers in Nairobi routinely run it beside mains cabling, since the optical core ignores interference that copper HDMI picks up.
Does the UGREEN HD178 support ARC or eARC?
No. Audio Return Channel needs sound travelling backwards from the TV to an amplifier, and this is a one-direction optical cable by design. Sound moves from source to display only. If you want TV audio going back to a soundbar, run a separate short HDMI lead between the TV's ARC port and the soundbar. Ask our Kimathi Street team and we will match the right cable to your room.
How much does it cost in Kenya and how quickly can I get it?
The UGREEN HD178 25M sells for KSh 6,000 at Mascom International on Kimathi Street. Nairobi and its environs receive same-day delivery. All other major towns get it within 1 business day. You pay when the cable reaches you, not before. Call or WhatsApp +254 708 852 521 to confirm stock, and tell us your actual run length so we can check whether 25 metres is the right size.
Technical Specifications
Signal Transmission and Bandwidth Capacity
- HDMI 2.0 standard carries up to 18Gbps, enough headroom for 4K 60Hz video with full color data
- Active optical construction converts the electrical HDMI signal into light, then converts it back at the display end
- Optical core resists electromagnetic and radio-frequency interference, so mains cabling running alongside does not corrupt the picture
- Signal strength at metre 25 matches metre one, removing the gradual fade copper leads show past 10 metres
- No repeater, booster, or extender box sits in the middle of the run, so nothing extra can fail
- HDCP 2.2 copy protection passes through intact, which matters for Netflix, Showmax, DStv, and Blu-ray sources
Video Resolution and Color Handling
- Supports 4K UHD at 3840 x 2160 pixels and 60 frames per second, the ceiling of HDMI 2.0
- Color depth options run 24-bit, 30-bit, 36-bit, and 48-bit, giving smoother gradients on large projected images
- Pixel formats cover RGB, YCbCr 4:4:4, 4:2:2, and 4:2:0, so spreadsheet text stays sharp at distance
- HDR10 passes through for wider separation between bright and dark areas on compatible displays and projectors
- 3D video signals are carried, useful for older 3D projectors still in service at training centres
- Lower resolutions including 1440p, 1080p, and 720p run without conversion, so older laptops connect without fuss
Audio Format Support and Sampling
- Audio sampling reaches 24-bit at 192kHz, the top of the HDMI 2.0 audio specification
- Carries Dolby TrueHD and DTS-HD Master Audio, the lossless soundtracks found on Blu-ray discs
- Object-based formats Dolby Atmos and DTS:X pass through to a compatible AV receiver or soundbar
- Standard LPCM, AC-3, and DTS streams are handled for everyday broadcast and streaming content
- Audio and video sync holds across the full run, so speech matches lips on stage screens
- Up to 32 audio channels are supported under the HDMI 2.0 specification this cable follows
Device Compatibility and Directional Setup
- One connector is marked Source and plugs into the laptop, console, decoder, or media player
- The opposite connector is marked Display and plugs into the projector, monitor, TV, or video wall
- Reversing the two ends produces a blank screen, so check the printed labels before pulling cable
- Works with PlayStation 5, Xbox Series X, Apple TV, DStv decoders, Blu-ray players, and Windows or Mac laptops
- Directional design means ARC and eARC audio return are not available on this particular run
- Both ends use full-size HDMI Type A male plugs, the standard 19-pin connector found on TVs
Cable Construction and Connector Build
- Aluminum alloy connector housings protect the internal conversion chips from knocks during installation and cable pulls
- Gold-plated contacts resist the corrosion that humid coastal air in Mombasa and Diani causes over years
- Hybrid build combines glass optical fiber with copper conductors inside a single slim outer jacket
- Slim profile bends more readily than thick copper HDMI, which matters when routing through ceiling voids
- Cable weight sits far below copper of the same length, reducing strain on HDMI ports over time
- Supplied at 25 metres, one of several lengths UGREEN produces in the HD178 optical range
Installation Requirements and Power Draw
- No external power supply is needed; the cable takes its operating current from the HDMI ports
- Power draw stays under 250mW, low enough that source devices supply it without a separate socket
- Hold the connector housing, not the cable body, when plugging and unplugging to protect the fiber
- Avoid bending the cable into tight kinks, since glass fiber cracks where copper only flexes
- Do not fit HDMI switches, splitters, or converters mid-run, as these break the optical signal path
- Plug-and-play operation needs no drivers, no configuration, and no software installation on Windows or macOS
Package Contents
- UGREEN HD178 HDMI Fiber Optic Cable 25M, factory-coiled with connector caps fitted
