Transporting multi-channel analog and digital TV, voice, and data across our hybrid fiber-coaxial (HFC) network requires an optical transmitter that maintains high carrier-to-noise performance over long distances. The FF-DT1310NM 1310nm Optical Transmitter converts incoming 47–862MHz RF amplitude signals into a clean 1310nm optical signal for single-mode fiber distribution. Its DFB laser incorporates Automatic Temperature Control (ATC) and Automatic Power Control (APC) circuitry to preserve laser lifespan and output stability. The selectable AGC/MGC operating modes and digital automatic RF drive processing keep C/N, CTB, and CSO parameters tuned to optimal levels. At a $599 price point, it offers an incredible balance of performance and value for HFC headend deployments.

Upgrading regional CATV distribution nodes requires headend hardware with comprehensive protection features and seamless remote management. This 1U stainless steel rackmount transmitter features an integrated microcomputer monitoring circuit and dual power supplies for uninterrupted operation. Advanced multi-frequency RF pre-distortion technology using GaAs devices and complete SMT construction significantly improves signal quality across the entire bandwidth. Crucially, the built-in RF power detector and RF relay shutdown function automatically guard the DFB laser against overload damage if input levels spike. Real-time parameter monitoring via the front-panel LCD and rear RJ45 network interface gives our network operations center total control.
