HDMI (M) to HDMI (M) Plenum Cable with Ethernet - 45'

The Kramer CP-HM/HM/ETH-45 is a 45-foot plenum HDMI cable with Ethernet and male HDMI connectors at both ends. Its specifications identify a focused cable configuration for installations requiring an extended, fixed-length HDMI connection, Ethernet capability within the HDMI cable designation, and a plenum-designated cable.

Ideal Use Cases

This model is suited to projects where a 45-foot cable route is appropriate and both connected devices provide compatible HDMI receptacles. The length can accommodate endpoints positioned farther apart than would be practical with a short equipment or patch cable. Potential applications include connecting HDMI-equipped components across a room, between installed equipment locations, or through a planned cable pathway.

The plenum designation makes this model relevant when the installation plan specifically calls for a plenum HDMI cable. Its male-to-male connector arrangement is intended for a direct cable path between two compatible HDMI endpoints. Because the cable also carries an Ethernet designation, it is appropriate when HDMI with Ethernet is among the documented connection requirements.

Why Choose This Model

The primary reason to select the CP-HM/HM/ETH-45 is its exact combination of length, connector configuration, plenum designation, and Ethernet capability. The cable measures 45 feet and does not require interpretation of an approximate length range. Both ends use male HDMI connectors, making the endpoint requirements clear before installation begins.

The SKU and model number also correspond directly to the listed configuration. This helps distinguish the cable from shorter Kramer C-HM/HM products and from HDMI cables that do not carry the plenum or Ethernet designations stated for this model.

Installation and Integration

Before installation, map the complete cable route and confirm that 45 feet provides enough distance for the intended pathway. Route calculations should account for the actual positions of the two HDMI ports, changes in direction, and any additional length needed to place the connectors without excessive tension.

Both ends terminate in male HDMI connectors, so the planned endpoints should accept male HDMI plugs. If the system uses a different connector gender, wall plate, coupler, extender, or adapter arrangement, those components must be evaluated separately because no adapters or installation accessories are identified in the supplied product data.

The product is described as a plenum cable, but no additional certification details, jacket specifications, dimensions, or operating-temperature information are provided. Installation requirements should therefore be checked against the documentation and rules applicable to the project. No mounting hardware or in-box accessories are specified.

Performance Highlights

The confirmed performance-related feature is HDMI connectivity with Ethernet. The supplied data does not identify an HDMI version, supported resolution, refresh rate, HDCP version, ARC or eARC support, or quantified bandwidth for this specific model. Those capabilities should not be assumed from the connector type alone.

Compatibility decisions should be based on the confirmed 45-foot length, male-to-male HDMI configuration, Ethernet designation, and plenum designation. For projects with a required video format or protocol version, verify those requirements independently before specifying the cable.

What Makes It Different

This cable is defined by four concrete attributes in one model: a 45-foot fixed length, male HDMI connectors on both ends, an HDMI with Ethernet designation, and a plenum designation. Together, these details separate the CP-HM/HM/ETH-45 from cables with different lengths, connector arrangements, or installation classifications.

The model number and SKU provide a precise reference for purchasing and project documentation. This is particularly useful when the required cable must be identified by more than the general description of an HDMI cable.

Final Assessment

The Kramer CP-HM/HM/ETH-45 is a clearly specified option for a project requiring a 45-foot male-to-male plenum HDMI cable with Ethernet. Choose this model when its length, connector gender, and stated cable designations match the planned route and endpoints. Because detailed signal-format, construction, certification, and warranty information is not included in the available data, those factors should be confirmed separately whenever they are mandatory project requirements.
