  • Leverage evolving FPGA technology improvements for your next product

We offer custom hardware design and on-site manufacturing services for Remote PHY modules, suitable for integration into existing or in-development fiber node products.

Calian, Advanced Technologies offers Headend technology products and solutions for broadband operators, content providers, and equipment vendors developing solutions for Cable Headends.

Cable Modulator Solutions
We excel at developing innovative Cable Modulator solutions to address not only challenging technical requirements but also streamlined cost-effective solutions.  Calian, Advanced Technologies can customize cable modulators for your product and design requirements including digital video QAM or DOCSIS 3.1 OFDM modulator requirements for HFC networks or MDU applications.

HydraQAM – Offering 128 QAM Channels from a Single Card
our HydraQAM card delivers next-generation QAM modulation technology as a commercially available, off the shelf card.  It offers 128 channel, high-density PCIe QAM modulator card offering compelling value on a per QAM basis while providing a path to full CCAP densities and DOCSIS 3.1.

HydraQAM is ideal for CMTS, CCAP, and video EdgeQAM products.

  • FPGA firmware based design provides flexibility for future upgrades & improvements
  • Each QAM channel can turn off individual channels or set to unique power level/frequency
  • Channel frequency agility, scalable to meet increased or reduced channel densities
  • Easily integrate into legacy networks to accommodate existing traffic
