Harmonic is well known in the cable industry as a key supplier of DOCSIS equipment. However, as the cable and telecom industry continues to expand its fiber reach, Harmonic has been taking a more active role in developing fiber-based broadband products.

With many of its cable operator customers being in a transition phase, Harmonic is offering products that enable a DOCSIS-to-PON migration. One example of this move is the SeaStar Optical Node, which allows broadband connectivity for lower-density multi-dwelling units (MDUs). The node converts existing in-building coax cabling into a high-speed broadband conduit. 

We recently caught up with Hy Huynh, Vice President of Fiber Products at Harmonic, to discuss the evolving landscape of fiber broadband.
