1. Introduction CYR 860x Optical Node is a high performance four output optoelectronic node. The model of CYR860x can be configured with a variety of forward optical receivers and reverse optical transmitters, providing flexibility for use in multiple applications. The module design is suitable for duplex HFC network development and scalable in broadcast & TV, telephone and data transmission at the edge of art. The CYR 860 station is widely used in the Metro area HFC Network system from medium to large scale city. Each station can support three forward optical receivers, two reverse return transmitters and two power supply mode. Redundant optical receiver and transmitter capability allows optical path redundancy, enabling network reliability. All of the modules are plug and play and can be connected or communicated within the station. 2. Main Features: A. Four high level forward individual outputs (108dBuv) B. 1GHz RF platform: Forward 52-750MHz or 87-870MHz ; Reverse:5-40MHZ or 5-65MHz. C. Three forward optical receiver/two hot-standby modules D. Two return optical transmitters (1310nm FP/DFB) E. Optional Status monitoring interface compatible with HMS F. The forward and reverse channel can be switched on or off by the embedded corresponder remotely. G. Multi network management protocol compatible and related with the local geography information system H. Local RF signal Mix in port and reverse signal Mix out Port I. Optical Receiving Range: +2dBm to -6dBm J. 15A Power Current passing K. AGC module L. Surge protection both inputs /outputs Ports
