AT5226 DMOD Transmitter
ACT AT5226 1RU 2.6GHz 1550nm Direct-Modulated (DMOD) Laser Transmitter offers a flexible and scalable optical transmission for high quality CATV & SAT-IF video in short, medium distance FTTH 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. AT5226 DMOD series transmitters are capable of delivering analog and digital video transmission up to 15km, all Digital loading up to 45km, with intuitive front panel LCD display to make operator’s daily operation easier. The optical transmitter is packaged in a self-contained 19” sub-rack of 1 RU with universal mains power supply and SNMP management. The optical output power level can be ordered at either 6 dBm, 8dBm or 10dBm with single or dual power supply for redundancy. Combined with ACT AT5200 Multiport EDFA optical amplifier, AT5226 DMOD transmitter provides the most cost-effective solution for short, medium IPTV, VOD and traditional CATV & SAT-IF services in HFC & FTTX networks.
