1U Series 1550nm Directly Modulated Optical Transmitter
Compact 1U rack mount 1550nm directly modulated optical transmitter for CATV HFC FTTH networks, low distortion, high stability, wide input power range, carrier-grade transmission equipment for residential and community fiber optic systems.
Product Features
Premium Quality: Adopts low-chirp, high-linearity DFB laser and advanced RF pre-distortion technology. It maintains excellent CNR performance while optimizing CTB, CSO and SBS indicators, delivering outstanding overall transmission quality for optical network systems.
High Flexibility: Features field-switchable AGC/MGC working modes and on-site adjustable OMI optimization. It can be flexibly adapted to various network transmission conditions to match different project application scenarios.
Superior Reliability: Equipped with built-in dual power supply, supporting both cold and hot backup operation within the 86~265Vac wide mains voltage range. The chassis adopts automatic temperature control heat dissipation design for stable long-term operation. All technical performance indicators are superior to industry standard requirements.
