Optical transmitters can modulate radio frequency signals into 1310nm/1550nm optical signals for transmission. They are widely used in medium - and long - distance digital and analog signal communication, and are suitable for medium - sized television signal transmission and FTTH network deployment. Equipped with a stable temperature control and heat dissipation system, they feature low power consumption and are an ideal choice for CATV secondary network transmission.
Equipped with predistortion correction technology and RF power automatic processing technology, it can automatically optimize the drive level in real time to ensure that the core broadcasting transmission indicators such as C/CTB (Carrier-to-Composite Triple Beat Ratio) and C/CSO (Carrier-to-Composite Second Order Ratio) always remain at the optimal values, achieving low-distortion and high-fidelity signal output.
Comprehensive support for the mixed signal transmission of digital and analog televisions: The externally - tuned models are suitable for ultra - long - distance transmission (with a maximum digital signal transmission distance of 150 km and a maximum analog signal transmission distance of 100 km), while the directly - tuned models are suitable for medium - and short - distance transmission (with a maximum digital signal transmission distance of 35 km and a maximum analog signal transmission distance of 25 km).
It supports multiple power supply modes such as AC, DC, and UPS. Optional dual - power supply can achieve 0 - second switching, and it features intelligent voltage regulation, thoroughly resolving issues related to power outages and unstable power supply.
