One of the primary time savers in permanent installation and remote setups is AV composite cable and among its extensive cable line, Canare offers a variety of AV composite cable types for OB vans, ENG/EFP applications, and AV combo snakes. A2V1 provides two 25 AWG balanced audio lines in twisted pair with a foil shield and drain wire along with a single 75Ω video coax channel. Also available is the A2V2-L with two audio, two video, and four lines for intercom or tally triggering. In addition there are cables with various multiples of audio and video lines. Also from Canare is the LF series hybrid fiber/copper camera cable combining fiber with separate conductors for power and control.
Crestron’s CBL-HD-certified HDMI interface cable is a Category 2 HDMI cable with 24k gold-plated Type A connectors to support 1080p60 HDTV with 16-bit color depth. Capable of handling resolutions up to WQXGA, the cable is sheathed in a High-flex CL3-rated jacket and is available in popular lengths up to 30ft. The MP-WP125 wall plate is typical of Crestron’s Media Presentation wall plates and provides eight gold-plated RCA connectors color-coded for component and composite video along with stereo sound. No stranger to the fiber realm, Crestron also offers the high-performance CresFiber 8G, a gradedindex multimode fiber cable tested to wavelengths up to 1550nm.
Designed to transport high-speed digital DVI and HDMI signals with bit rates up to 2.25Gbps over long distances, the Super High Resolution (SHR) cables from DVIGear maintain high signal integrity. The SHR cables form active cable assemblies when used with DVIGear’s Active Cable Extenders (ACE) for fully DVI and HDMI compliant transport up to 197ft. The DVI-2300-FO series series provides optical transport for DVI with resolutions up to 1080p and PC resolution up to 1920x1200 in a hybrid copper/fiber cable supporting bidirectional DDC communication. The DVI-2500-FO series series consists of four high-speed glass fibers and six copper wires and carries HDMI signals over 300ft.
Extron Electronics has introduced its new OM4 MM P laser-optimized multimode fiber cable for signal distances up to 2km with OM4 performance. Also new is the LockIt HDMI cable-lacing bracket. This is used to secure HDMI cables to a product’s connectors, reducing stress on the connector and reducing intermittent signal loss. Extron’s new Captive Screw Connectors for DC power, audio, and control connections have a strain-relief tab that provides a tie-down point for a securing a zip tie. They also feature an extended barrier between the two-wire openings to prevent shorts. In addition, DC power connectors feature a lock-out tab that prevents the connector from being inserted into a blue signal port on the back of an Extron product.
The HDMI Extreme cables from Gefen offer an integrated HDMI cable solution composed of fiber-optic cable and electro-optical components built into the HDMI connector at the endpoints. These cables come in several lengths and are HDCP-compliant. A single power supply is included for use on the display end of the cable in case the video source signal is too weak to power the entire extension distance. Also from Gefen is the DisplayPort fiber-optic extender cable, which runs USB 2.0 up to 1000ft. on single-mode cable. Offering plug-and-play connectivity between DisplayPort computers and Apple’s new 27in. LED Cinema Displays, the DisplayPort to Mini-DisplayPort adapter adapter is another recent addition.
