TELESTE CXE880 optical receiver

0
Manufacturer:
Type:
Options receiver/node:
AGC

 

Description:

The CXE880 node for deep penetration of optics. It is designed for the cases where quality performance and economic efficiency. is required. Provided all requirements of the modern coaxial networks are provided: forward channel up to 1000 MHz and backward channel up to 85/100 MHz. Optical connectors are located outside, which makes it easy to install. 

Advantages:

  • Forward channel up to 1000 MHz;
  • Backward channel up to 85/100 MHz;
  • Simpleadjustmentwithout interrupting thesignal;
  • AGC on the basis of optical input power(OLC);
  • Opticalremote monitoring of the key parameters;
  • Wide backward channel;
  • Low noise level;
  • GaAs output amplifier;
  • OMItest point;
  • There are no additionalinserts in theconfigurationwith a single output;
  • Optical power level indicator;
  • Excellent Power supply.
