Kramer CP-HM/HM/ETH 45 ft Plenum HDMI Video Cable

Kramer Electronics, founded in Israel in 1981, has built its name on professional audiovisual signal infrastructure for corporate, educational, and broadcast environments. The company's video cable lineup spans the full range of contemporary signal types — HDMI 2.1 with HDR and 8K support, fiber-optic HDMI runs for long-distance installations, 12G-SDI and 6G-SDI BNC cables for broadcast workflows, and DisplayPort 1.4 cables for high-resolution computer-to-display applications. Active and optical HDMI cables under the Kramer C-HM/HM/A series and the Cable+Plus fiber optic line address the long-run installation challenges that traditional copper HDMI cannot meet, supporting runs up to 100 meters at 4K60 4:4:4.

Kramer's approach to cable manufacturing emphasizes installer-grade construction with reinforced strain relief, certified bandwidth testing, and Premium HDMI Cable Certification on applicable models. The company maintains tight integration between its passive cabling and its broader signal management ecosystem of switchers, extenders, and matrix routers, with cables specified to perform reliably alongside Kramer's own EDID handling, HDCP repeating, and signal regeneration hardware. Many product lines are bundled into Kramer Connect installation kits with matched plates, couplers, and color-coded jackets to support the standardized AV cabling practices common in commercial integration projects, where consistency across hundreds of rooms is the dominant design constraint.
