Product Description

China manufacturers catv line bidirectional amplifier

 

Product Description

SA1100 outdoor trunk bidirectional amplifier is mainly used for bidirectional trunk transmission of CATV television image signal, digital TV signal, telephone voice signals and data (or compressed data) signal. Advanced and mature circuits, scientific and reasonable process structures and high quality materials, ensure the excellent performance. It is the first choice equipment to build large or middle-sized CATV bidirectional transmission network.
 

Performance Characteristics

 

• 1003MHz bandwidth design.
• Forward path: The pre-stage adopts GaAs MMIC, output stage adopts the newest imported high index power doubly module, achieve high output level, low distortion and high SNR.
• It is more convenient to debug because of the plug-in duplex filter, equalizer, attenuator, output tap and the scientific and reasonable on-line detection ports.
• The equipment can long time continuous work steadily under outdoor bad environmental condition. Because of the aluminum waterproof housing, high reliability switching power supply and strict lightning protection system.

Note: The parameters of this manual are measured when adopting imported NEC module. Use other module, the indexes will be a little different. Attention when use!
 Notes

1. Strictly control the output level when use. When there are too many channels or concatenations, the output level should be appropriately reduced to ensure the transmission quality. Generally speaking, a dozen programs can be controlled in about 93 ~ 105dBμV.
2. Please rational use EQ inserter to ensure the flatness of long-distance transmission and the low-frequency side SNR.
3. Strictly waterproof when use in outdoor. Please tighten the cover screws.
4. B type (AC60V power supply) equipment is strongly recommended to use power supply with overcurrent, over voltage and lightning protection device.
5. Please pull off the overcurrent fuse when no need overcurrent! Check if there is short circuit when need overcurrent.

   Repair items: The product installed or maintained by professionals.
