Pulse's New Multimedia over Coax Diplexers Enable Triple Play

MoCA diplexers provide video transmission over existing coax cable.

October 26, 2006 - Pulse®, a Technitrol Company (NYSE: TNL), a worldwide leader in electronic component and subassembly design and manufacturing, announced a new series of diplexers that meet Multimedia over Coax Alliance (MoCA®) standards to enable radio frequency (RF) distribution of enhanced triple play (voice, data, and video) services. The diplexers are used in products such as set-top boxes, gateways, network interface devices (NIDs), for video over the telephone network (Telco TV), Internet protocol TV (IPTV), and cable TV applications.
Today's homes commonly have two different types of communications wiring: coaxial cable primarily for television and twisted pair wire primarily for telephone/data use. Normally, video cannot be carried reliably over standard twisted-pair wire, and rewiring with high-performance twisted pair is expensive. Instead, MoCA technology enables Telco TV by utilizing RF frequencies over the existing coaxial cable, which is used to transmit all three triple play services within the home.
The first three members of Pulse's rapidly expanding MoCA diplexer family are models C6039, C6058, and CX6077. These diplexers are designed to be built into residential triple play distribution products - including optical network terminations (ONT), set-top boxes and gateway devices - and to work with integrated circuits that meet MoCA standards.
Diplexers contain both low- and high-pass filters, to selectively transmit low- and high-frequency signals, respectively. Cable TV signals are typically in the low-pass band, while data and IPTV signals are high-pass. Frequency ranges for each filter are as follows:


Low pass (MHz)

High pass (MHz)

Impedance (ohms)


5 - 860











Pulse diplexers are highly resistant to electromagnetic interference and are fully shielded and grounded.
Parts in the MoCA family come in a variety of configurations with through-hole and surface mount applications. Parts include integrated F-connectors and extended temperature applications. The Pulse MoCA family is being expanded to include single filter designs, triplexers, switched filters, external devices, and weatherproof enclosures. In addition to catalog components, Pulse designs and manufactures custom parts that meet customers' specific requirements.

"Pulse has been working with the MoCA Alliance and its member companies since its inception, and has been developing the diplexer product family with many leading-edge triple play product suppliers for the past two years," explained Fred Roden, senior product manager for Pulse Telecom Division. "These products are natural extensions of our Pulse RF, LAN, and telecommunications product lines. With technical resources and cost-effective, high-volume manufacturing, Pulse is very well positioned to meet the needs of this dynamic market."
