ANGA COM 2014. Booth P28. US, microwave, cable and satellite technology pioneer MACOM (or M/A Com to oldtimers) is presenting its active and passive components within the infrastructure and customer premise equipment, enabling deployment of DOCSIS 3.1 equipment by cable operators, to keep up ‘with the exponential growth in data demand while leveraging previously deployed fibre and copper’.
In what the vendor calls ‘a full refresh of the equipment toolkit’, it offers a range of new higher power, linearity and bandwidth amplifiers, improved rejection filters, and a full new suite of power dividers and couplers.
The line-up on show consists of DOCSIS 3.1 push-pull and power doubler GaAs solutions in plastic and hybrid formats. These GaAs infrastructure amplifiers offer multiple system operators higher linearity and output power with extended 1.2GHz bandwidth.
Diplex filters that deliver very high isolation and return loss while simultaneously maintaining the lowest possible insertion loss. As the higher power levels combined with extended frequency requirements of DOCSIS 3.1 place much greater demands on the passive components in the system amplifier. Passives need to exhibit multi-octave flat response and not contribute to system distortion.
High performance, surface mount triplex filters, which cover the 42/54, 65/88, 85/108 MHz, and 204/258 MHz bands, are MoCA 2.0 compliant and fully footprint compatible, allowing for simplified front-end designs and quicker design cycles. According to MACOM ‘extremely high performance filter technology is needed to simultaneously support next generation MoCA systems and new DOCSIS 3.1 interfaces to the core network’.
Reverse path single-ended, differential and variable gain amplifiers, with higher 300 MHz bandwidth to meet DOCSIS 3.1s extended frequency bands in both the forward and reverse paths.
And for fibre operators FTTx amplifiers that have been developed specifically to meet Radio Frequency over Glass (RFoG) and Passive Optical Network (PON) system requirements.
