Fiber Negative Dispersion Compensator for Long-Haul CATV Transmission
Negative dispersion compensation module (DCM) used for 1550nm CATV long-distance optical transmission, accurately compensates fiber chromatic dispersion, stable optical performance, low insertion loss for HFC trunk networks.
Product Features
Premium Quality: Adopts original imported compensation fiber with ultra-low temperature sensitivity and moderate insertion loss, ensuring stable and reliable optical performance for long-distance transmission systems.
High Flexibility: Features a wide compensation bandwidth ranging from 1525nm to 1565nm, supporting 80%~100% slope compensation across the entire C-band to meet diverse dispersion correction requirements.
Excellent Reliability: Designed as a wide-spectrum passive optical component, it delivers highly stable continuous operation in HFC and optical fiber transmission networks without additional power consumption.
