AT5100 DMOD Transmitter
ACT AT5100 1RU 1550nm Direct-Modulated (DMOD) Laser Transmitter offers a flexible and scalable optical transmission for high quality video in short, medium distance CATV networks. It was designed with high linearity and low chirp DFB laser, with built-in pre-distortion compensation and AGC close loop control for improved performance.
• Suitable for short, medium distance FTTH applications
• Suitable for long distance 1550 nm QAM Overlay applications, up to 70km
• Optimized models for analog and digital signal up to 15km
• High linearity and low chirp DFB laser
• Built-in pre-distortion compensation and AGC closed loop control,
• Dual redundant hot-swappable AC or DC power supplies
• Stimulated Brillouin Scattering (SBS) suppression for optimized CSO
• Front-panel LCD for local monitoring of transmitter status
• Local or remote monitoring and configuration
• SNMP/HTTP monitoring, management and control
