The IPRF-QAM line of modulator blades from Thor are high density edge modulators designed to take content delivered via an IP backbone or CDN system and modulate the programming onto digital QAM cable channels for distribution over coax. This product group includes a 1RU chassis supporting up to 3 modules and a 4RU chassis supporting up to 12 modules. Each module is a fully independent system, with its own dedicated management and is fully isolated from the other modules in the chassis. The H-IPRF-8QAM module supports an impressive density for its small form factor. Each module supports 8 full RF channels on adjacent frequencies. The 8 channels are individually mapped for input IP addresses, with each channel supporting up to 32 single program IP inputs or one multi program IP and port value. The IPTV programming input is standard headend format, meaning basic UDP unicast or IGMP multicast address and port format. This impressive density allows a single chassis to convert an IPTV Ethernet backbone feed to be converted to a full digital cable lineup with hundreds of channels.
