Sxg402 4 Ports Output CATV Trunk Amplifier with Return Path and AGC
Our company strictly follows the quality management system, so that the quality of all our 220V Ftth Catv Optical Receiver, 4 Port Onu Wifi Catv, Dual Mode XPON ONT can be effectively controlled and ensured in the first process. We are based on a high starting point, large investment, high-level operations, adhere to high standards, zero defects, and refinement, seize every development link, and strive to build a 'rest assured' brand. Our company firmly believes that the trust of customers is the greatest affirmation of the company. Only by making customers grow, can the company thrive.
SA1200 outdoor bidirectional AGC trunk amplifier is a new high gain amplifier. It adopts mature and optimized circuit design, scientific and rational internal process, high quality materials, and built-in high performance AGC control circuit, which ensures the stable gain and low distortion. This CATV trunk amplifier with return path is the first choice equipment for large and medium-sized CATV bidirectional transmission network.
Performance Characteristics
■It is more convenient to debug because of the plug-in duplex filter, fixed equalizer and attenuator, plug-in output tap, and the scientific and reasonable on-line detection ports.
■Built-in optimal designed high performance AGC control circuit, make the control more precise and the signal operation more stable.
■CATV trunk amplifier with return path 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.
