Product Description

1. Product Summary
    HJ series outdoor optical node are two-way optical joint equipment that based on several years research experience of CATV HFC fiber transmitting equipment, specifically developed for the HFC structure two-way metropolitan area broadband network. When designed the product, we have fully considered the FTTC (Fiber to the Customer) network topology, the engineering technical problems of CATV bidirectional return path noise, and the high reliability network security transmission requirement of modern CATV business; optimize the internal circuit structure, and built a perfect states monitoring circuit. Reserved the network management interface which compatible with the SNMP standard, achieve remote network management monitor by the network management transponder. It is the first choice equipment to construct the high-quality bidirectional HFC metropolitan area broadband network.
2. Performance Characteristics
  • Full CPU control the machine work, LCD displays the parameters, such as the input/output level. Variable control operation is convenient and intuitive, and performance is stable. Reduced a large number of optional accessories.
  • Adopt advanced optical AGC technology, optical AGC control range: +2dBm ~ -9/-8/-7dBm adjustable.
  • Two-channel optical signal receiver backup each other, can set automatic switching condition arbitrarily, also can be set to manual switching.
  • Optimizing circuit design, SMT production process, optimizing the whole signal path, made the photoelectronic signal transmit more stable, RF linear index higher.
  • Professional RF electrical adjustable attenuation chip, RF electrical adjustable equilibrium circuit, good linearity, high precision.
  • GaAs amplifier device, power doubler output, high gain and low distortion.
  • The return path adopts professional RF electrical adjustable attenuation chip instead of the three-state switch.
  • Reserved the data communication interface, can connect the Ethernet transponder, access to the network management system, the variables can be remote controlled by the NMS.
  • Reserved the C-CMTS (forward/return path) RF interface, perfectly support DOCSIS EOC networking scheme.
