Import Dvb-C Ip Qam Modulator — Buy in Bulk from Supplier in China

The JXDH-6503C DVB-C IP QAM Modulator is a compact 1RU device designed for digital cable transmission, featuring one 1000Mbps IP input and one SPF input. It supports RF output modulation from 16QAM up to 256QAM, enabling flexible bandwidth allocation for multi-channel broadcast environments. The unit operates with a single Ethernet management interface, allowing remote configuration without dedicated serial or GUI hardware.

The modulator uses standard DVB-C protocols and is built for continuous operation in headend or hub environments. It is typically deployed in systems requiring low-latency signal aggregation from IP streams, such as IPTV platforms or cable MSOs. The chassis is designed for rack mounting with passive cooling, and the component layout avoids unnecessary amplification stages to reduce noise floor. Common industry tolerances for output level are ±2 dBmV across the 47 - 862 MHz band, though exact output power is not specified by the supplier.

This modulator is purchased by regional cable operators, broadcast integrators, and satellite-to-cable conversion service providers in Asia and Eastern Europe. Buyers typically require units in quantities of 5 or more for network upgrades. Packaging is standard industrial carton with foam inserts. Lead time is not confirmed, and Incoterms must be negotiated directly with the supplier. No certifications are listed, so buyers should request CE or FCC compliance documentation prior to import.
