 CHP Max5000 —The CHP Max5000 Advanced 1GHz QAM Transmitters are ideally suited to transport digitally encoded video (16/64/256-QAM) and QPSK data from the headend to a hub or node. These forward path transmitters can accept narrowcast QAM signals, telephony, etc. from 550 to 1002MHz and convert the RF input to an optical output at DWDM wavelengths available at odd ITU channels 21 through 61. The optical output power of 10dBm provides a transmitter reach of up to 150km when used in conjunction with an EDFA. CHP Max5000 1GHz transmitters are dual-input, 10dBm output, hot-swappable transmitters with integrated management through the local Craft GUI and remote management via SNMP HMS-compliant interface for external connection to an element manager.
The 1GHz transmitter's dual-input capability provides isolation that is much superior to alternative offerings, enabling the possibility to use "broadcast" QAM channels on one input, while using "narrowcast" QAM channels on the other input without cross-talk impairments. The high isolation eliminates having to add external devices to achieve similar performances, thereby lowering CapEx even further and reducing system complexity.
