PCT International Debuts New Drop Amplifiers with MoCA Filters

By Nathesh, TMCnet Contributor

PCT International, a manufacturer of last mile and access network solutions for broadband communications networks, has released a new set of subscriber amplifiers that can optimize in-home networking built over the Multimedia-over-Coax (MoCA) standard.

According to a company press release, the drop amplifiers with MoCA filters can isolate home networking frequencies above 1 GHz and use low pass filters to confine the 1125-1525 MHz MoCA signals to the home network -- and to ensure the low port-to-port isolation that minimizes loss of MoCA networking signals. The loss of cable signal quality in the drop is also accounted for using forward path equalization technology integrated into the amplifiers.

The company will unveil these amplifiers at the SCTE Cable-Tec Expo. There it will demonstrate how its drop amplifiers with MoCA filters effectively isolate home networking frequencies above 1 GHz from legacy cable telecommunications frequencies, minimizing signal loss and simultaneously maximizing voice, video and data service quality and home networking performance.

PCT has stated that the rise in installations of new subscriber services has changed the signal levels within the broadband network which in turn has increased the demand for high quality drop amplifiers. The company’s amplifiers offer a cost-effective way with advanced performance in distortions and pass band response. Their drop amplifiers have improved performance and ultra-low noise amplification of broadband signals for subscriber drop installations.

In the release, Jon Wang, vice president of RF engineering for PCT International (News - Alert), said MoCA allows MSOs to provide advanced services such as multi-room DVRs and faster connectivity to take advantage of higher bandwidth with DOCSIS 3.0. While the MoCA standards themselves have become pivotal in most discussions related to home networking, the role of the drop network architecture is crucial to the end result. The company has worked closely with major cable system operators to carve a new technological approach that simplifies installation and ensures the best possible in-home experience.

The amplifiers are available with or without integrated modem ports and in the integrated modem port versions, a MoCA bypass connection enables in-home networking between the eMTA, set-top boxes and networked devices. The bypass version also has a passive RF link to the eMTA to ensure connectivity in the event of power or amplifier failures.

PCT International recently unveiled its Fiber Mini-Node and added new optical network passive components to EQ Link.
