Original system optimization control technology, RF predistortion technology to ensure excellent performance in the case of CNR system to obtain the largest CTB, CSO and SBS indicators.
Phase modulation technology of the external regulator to maximize the performance of the system CSO, to maximize the fiber into the optical power to obtain long-distance transmission, and SBS threshold 13,16,18 field adjustable , Can be applied to different network transmission.
19 "1U standard rack, built-in high-performance dual switching power supply, can be 85 ∽2665ac city network voltage in the hot backup work, MS-level automatic switch; chassis cooling can be automatic temperature control.
External modulator and laser is the most expensive device, the machine set up a microprocessor outside the tune.
Option status monitoring transponder to ensure compliance with the national standard and compatible with the SCTE HMS standard, can achieve network management monitoring.
