CATV TRUNK EXTENDER User Manual

(Broadband network amplifier)

 

 

ModelYTG7134-EA/B      YTG8134-EA/B  

Yatai-series field-type bidirectional Trunk amplifier is specifically designed for last “1km” of CATV transmission network. It has good property, low power consumption, high reliability, and excellent value for money, suitable for medium and small-scale bidirectional transmission network and multi-level transmission of trunk line or distribution networks with high requirements. It adopts MOTOROLAPHILIPSNEC imported module, with stable performance, low noise figure, high output level. It has two equalizers in the front end and in the back end with two outputs ports. Its branch and distribution can make change according to your needs. Its one input port and two output ports have over-current protection function (with over-current inserts shear inside). It is more convenient to debug because of the plug-in duplex filter, plug-in fixed(or adjustable) equalizer and attenuator, and the scientific and reasonable on-line detection ports.

The equipment can work steadily for a long time under bad outdoor environmental condition because of the aluminum waterproof housing, high reliability switching power supply and strict lightning protection system.

二、Precautions:

  • If number of channels is two much or continuous transmission series of amplifier is too much, to ensure the image quality, the output level should be appropriately reduced.                                                
  • In order to achieve better flatness and better low frequency band signal-to-noise ratio, you had better use the two equalizers simultaneously. If intermediate line band signal level is too high (about 80MHz-200MHz), you had better use equalizer shown in chart (no. 3).
  • Maximum gain means when attenuator, equalizer is zero, the gain of the branch outputs.
  • After installation, please check over current condition. If the circuit does not need over-current function, you must pull out over-current inserts, and use Multimeter to check if there is short circuit condition(using minimum resistance profile of Multimeter).
  • Maintenance matters: maintenance, installation is handled by professional person, and our company has commissioned local dealers for that matters. For technical advice, please contact local dealer or our technical department.
