Migrating from RF Coaxial to Full FTTH: A Practical Guide for Cable TV Operators

The 1550nm RF Overlay Advantage

Operators can deliver digital CATV channels using a 1550 nm optical transmitter coupled with GPON (1490/1310 nm) via a WDM (Wavelength Division Multiplexer). At the customer home, an FTTH optical receiver outputs standard RF coaxial cable to existing set-top boxes.

This allows operators to preserve their existing set-top box investments while eliminating costly RF line extenders and power supply amplifiers from street poles.

Phase-by-Phase Plant Conversion with CoreMap

CoreMap enables operators to map hybrid networks where active coaxial segments and new FTTH fiber clusters coexist. As each neighborhood migrates to fiber, the platform tracks the changeover seamlessly.
