RGB Spectrum HDMB2 – 15 m 4K 60Hz HDMI 2.0 Fiber Cable

Product Overview

The HDMB2 is a 15 m HDMI 2.0 fiber optic cable rated by RGB Spectrum for 4K 60Hz. It is specified where a 4K source or processor output has to reach a display further away than copper HDMI can reliably carry it — a rack-mounted head-end feeding a video wall across a control room, a projector at the back of an auditorium, or a display on the far wall of a large commercial meeting space. Using a fiber HDMI cable for that run removes the need for a separate extender pair, its power supplies and its rack space. The cable is directional, so the source and display ends are not interchangeable.

Product Description

Copper HDMI at 4K 60Hz becomes unreliable well before 15 m, which is why long 4K runs are normally solved either with an extender over structured cable or with a fiber HDMI cable like this one. The fiber approach keeps the link as a single HDMI-to-HDMI cable: there is no transmitter, no receiver, no CATx patching and no additional power at either end, and there is nothing in the middle of the path to fail or to be misconfigured. It also makes the run immune to the ground-loop and interference problems that appear when a long copper run crosses between racks, floors or buildings.

In an RGB Spectrum system the HDMB2 usually sits between a processor output and a display. It suits the four HDMI outputs on a QPX HIN or QPX DIN QuadPlex processor and the HDMI outputs on the Zio MD-4H-4 output card. Where a long run needs to feed two sinks, the 820 12214 1x2 HDMI 2.0 splitter is the matching distribution part, and where the display's timing or EDID behaviour is the problem rather than the distance, the SC-HD-2B scaler and frame rate converter and the EDID-EW-H EDID minder are the usual remedies. For a DisplayPort source over the same distance, the DPM2 fiber cable is the equivalent part.

Before ordering, confirm the measured cable path rather than the straight-line distance, including service loops at both ends and any conduit bend radius the cable has to follow. Confirm which end goes to the source, because a directional fiber cable installed backwards will not pass a signal. Confirm the HDCP version the sink requires, and confirm that both connector ends will physically fit the sockets and any pass-through plate or grommet on the route, since fiber HDMI connectors do not tolerate being pulled through a tight opening.

Key Features

• 15 m 4K 60Hz run in a single cable — The published length and rate cover long rack-to-display runs that copper HDMI cannot support at 4K 60Hz.
• No extender pair required — The link is HDMI in and HDMI out, so there is no transmitter, receiver, patching or extra power supply to install and maintain.
• Immune to electrical interference — A fiber signal path avoids the ground-loop and EMI problems that affect long copper HDMI and CATx runs between racks or floors.
• HDMI 2.0 signal support — The cable is specified by the vendor for HDMI 2.0, which is the interface RGB Spectrum processors and current commercial displays use.
• Thin, light and easy to route — A fiber HDMI cable pulls more easily through conduit and tray than a heavy 4K copper HDMI cable of the same length.
• Vendor-supplied for RGB Spectrum systems — Ordering the RGB Spectrum part keeps the long run inside the same support path as the processor it feeds.

Typical Applications

• Control room — Carries 4K 60Hz from a rack-mounted processor to operator and wall displays across a room where the copper distance limit would otherwise force an extender.
• Command center — Serves long, permanent runs to a video wall where a cable failure mid-shift is unacceptable and a passive single-cable path reduces the number of things that can fail.
• Operations center — Suits 24/7 rooms where displays are far from the head-end and the run has to cross power-dense cable tray.
• Auditorium — Reaches a rear-mounted or ceiling-mounted projector from a stage-side or rack-room source at full 4K 60Hz.
• Boardroom — Connects a credenza or closet rack to a large front-of-room display without a visible extender box behind the screen.
• Broadcast studio — Feeds monitoring and confidence displays over distances that cross a studio floor, with no electrical path between rack and stage position.
• Government space — Fits fixed-infrastructure installs where a single passive cable is easier to document, inspect and maintain than an active extender pair.

Frequently Asked Questions

Will this cable work with any HDMI 2.0 source and display?
It is specified as an HDMI 2.0 fiber cable rated for 4K 60Hz, so it is intended for HDMI 2.0 signal paths. Because RGB Spectrum publishes no datasheet for this part number, confirm the HDCP version and the exact timing your sink requires with Creation Networks before ordering for a critical path.

Does the cable need power at either end?
The vendor description does not state a power requirement, and the part is sold as a cable rather than as an extender pair. Many fiber HDMI cables draw their small operating current from the HDMI connector itself, so confirm this behaviour for your source device before you design a run with no local power available.

Is the cable directional?
Fiber HDMI cables are normally directional, with a marked source end and a marked display end. Plan the pull so the labelled source end finishes at the processor or player, and confirm the marking convention on the delivered cable before it is dressed into tray.

Can it replace a CATx extender pair on a long 4K run?
In most cases yes, and that is the usual reason to choose it: one passive cable instead of a transmitter, a receiver, two power supplies and a structured cable link. The trade-off is that the run length is fixed at 15 m and the cable cannot be re-terminated in the field.

What should I check before specifying the 15 m length?
Measure the actual routed path, not the straight-line distance, and add service loops at both ends. Also check every opening the connector has to pass through, because fiber HDMI ends are less tolerant of being forced through tight grommets and plates than copper connectors are.

How does it integrate with an RGB Spectrum processor system?
It is used as the display run from a processor output, for example from the HDMI outputs of a QuadPlex processor or a Zio output card. No configuration is involved on the processor side; the cable is transparent to the system once the link is established.

What warranty and support apply?
The RGB Spectrum manufacturer warranty applies to this part. Creation Networks supports specification and procurement, including confirming length, direction and connector fit against your drawings before the order is placed.
