FTTH Solution LED Display 1GHZ Optic Node
1. Product Summary
SR1004JL is our latest high-grade four-output CATV network optical receiver. The pre-amplifier adopts full-GaAs MMIC, the post-amplifier adopts the GaAs module. Optimized circuit design coupled with rich professional design experience, makes the equipment achieve good performance indexes. Microprocessor control, digital display the parameters, the engineering debug is especially easy. It is the main equipment to build the CATV network.
2. Performance Characteristics
* High response PIN photoelectric conversion tube.
*Optimized circuit design, SMT process production, optimized signal path, make the photoelectric signal transmission more smooth.
* Specialized RF attenuation chip, with good RF attenuation and equilibrium linear, high accuracy.
* GaAs amplifier device, power doubler output, with high gain and low distortion.
* Single-Chip Microcomputer (SCM) control equipment working, LCD display the parameters, convenience and intuitive operation, and stable performance.
* Excellent AGC performance, the AGC range is -9~+2dBm adjustable.
* Reserved EOC functional unit (optional).
* Return-path can select burst mode to sharply decrease the noise convergence and greatly improve the quality and reliability of the network operation.
*Reserved data communication interface, can connect withIIclass network management responder, access to the network management system.
