RGB Spectrum DPM2 – 15 m 4K 60Hz DisplayPort Fiber Cable

Product Overview

The DPM2 is a 15 m DisplayPort 1.2a fiber optic cable rated by RGB Spectrum for 4K 60Hz. It solves the same problem as its HDMI counterpart on the DisplayPort side of a system: getting a full-rate 4K signal from a rack-mounted processor or workstation to a display that copper DisplayPort cannot reach. DisplayPort is particularly length-sensitive at 4K 60Hz, so a fiber DisplayPort cable is often the only practical way to make a room-scale run without inserting an extender pair. The cable is directional and fixed in length, which makes path measurement the first design step.

Product Description

Copper DisplayPort at 4K 60Hz is typically limited to a few metres before link training becomes unreliable, and the symptom is rarely a clean failure — it is an intermittent black screen or a link that comes up at a reduced rate after a source reboot. A fiber DisplayPort cable removes that risk by carrying the lanes optically for the whole 15 m, with no active box, no CATx patching and no additional power in the middle of the path. It also isolates the two ends electrically, which matters when the run crosses between racks, floors or rooms with separate power feeds.

In an RGB Spectrum system the DPM2 typically feeds a display from a DisplayPort output, or feeds a processor from a DisplayPort source. It suits the DisplayPort 1.2 input on the QPX DIN QuadPlex processor and the DisplayPort outputs on the Zio MD-4D-4 and Zio AD-4D-6 output cards. Where the far end of the run has to terminate in HDMI instead, the 520 12408 DisplayPort to HDMI adapter is the matching part, and for an HDMI source over the same distance the HDMB2 fiber cable is the equivalent cable.

Before ordering, confirm the measured route including service loops, and confirm the DisplayPort version and rate each end has to negotiate — a 1.2a cable is specified for 4K 60Hz, not for higher-rate DisplayPort 2.x timings. Confirm which end is the source, since a directional cable fitted backwards will not link. Also confirm connector clearance at both devices and any plate or grommet on the route, and whether the sink requires a locking DisplayPort connector, because fiber assemblies vary in latch design.

Key Features

• 15 m DisplayPort run at 4K 60Hz — The published length and rate cover room-scale runs far beyond what copper DisplayPort will reliably link at 4K 60Hz.
• Single passive cable path — There is no transmitter, receiver or structured cable segment to install, commission or troubleshoot later.
• Electrically isolated ends — An optical path avoids ground-loop and interference problems on runs that cross between racks, floors or power domains.
• DisplayPort 1.2a signal support — The vendor specifies the cable for DisplayPort 1.2a, matching the DisplayPort interfaces on RGB Spectrum processors and output cards.
• Easier to route than heavy copper — The thin fiber assembly pulls through conduit and cable tray more easily than a 15 m copper DisplayPort cable would.
• Vendor-supplied for RGB Spectrum systems — Ordering the RGB Spectrum part keeps the long DisplayPort run inside the same support path as the processor it serves.

Typical Applications

• Control room — Carries a 4K 60Hz DisplayPort feed from a rack-mounted processor or workstation to operator positions across the room.
• Command center — Supports permanent video wall runs where a DisplayPort link has to hold full rate continuously and cannot depend on an active extender.
• Operations center — Suits round-the-clock rooms where sources sit in a secure rack well away from the displays they drive.
• Broadcast studio — Feeds monitoring displays on a studio floor from a rack room with no electrical path between the two positions.
• Boardroom — Connects a closet or credenza rack to a front-of-room display at 4K 60Hz without a visible extender behind the screen.
• Government space — Fits fixed installations where a single documented passive cable is preferred over an active device pair for inspection and maintenance.
• Auditorium — Reaches a rear or ceiling projector position from the source rack at full rate over a single run.

Frequently Asked Questions

Which DisplayPort rates does this cable support?
It is specified as a DisplayPort 1.2a fiber cable rated for 4K 60Hz. Higher-rate DisplayPort 2.x timings are not part of that description, so if your design needs 8K or high-refresh output, have the requirement confirmed with Creation Networks before ordering.

Can it be used on the input side of a processor?
Yes. A common use is feeding a DisplayPort 1.2 processor input, such as the input on a QPX DIN, from a source that sits some distance away. The cable is transparent to the processor once the link is established.

Is the cable directional?
Fiber DisplayPort assemblies are normally directional, with a marked source end and a marked display end. Confirm the marking on the delivered cable and plan the pull accordingly, because a reversed installation will not link.

Does it need external power?
The vendor description does not state a power requirement. Fiber DisplayPort assemblies commonly draw their operating current from the connector, so confirm that behaviour against your source device if no local power is available at either end.

How does it compare with a DisplayPort extender pair?
It replaces the transmitter, receiver, two power supplies and structured cable link with one passive cable, which reduces both rack space and failure points. The trade-off is a fixed 15 m length that cannot be shortened or re-terminated in the field.

What should be checked during installation?
Measure the routed path with service loops, verify bend radius through conduit, and check that both connector bodies clear the sockets and any wall plate or grommet on the route. Fiber ends should never be forced through a tight opening.

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