DFB Laser 1550nm Optical Transmitter For Telephone Communications
Summary
HS15205-19 Series External Modulation Optical Transmitter is the New High Performance 1550nm CATV External Modulation Optical Transmitter Model.19" 1U height All Aluminum Box Structure, easy to install on the 19" Standard Rack.
Model 15205-19 specification is 1550 Wavelength 2-Way 5dBm Optical Outputs, unit is dBm, -19means max value of SBS. the output signal spectral line is narrow, and it is more advantageous in the Long Distance Transmission. The main parts supplied by JDSU, Fujitsu, Bookham’s DFB Low Noise, Narrow Linewidth, CW Laser with Thermoelectric Cooler and JDUS, AVANEX CATV High Linearity External Modulator and Matched Pre-Distortion Plate.The Key Components adopt International Brands and our Company System Optimization Control Technology, SNMP Network Control Technology, so that the Whole Device Technical Performance Indicators fully reach the standards of Similar Imported Equipments.And for the cable television and telephone communications, to provide High-Quality Images, Digital or Compressed Digital Signals over long distances.
Features
High Quality: Original System Optimization Control Technology, RF Predistortion Technology maximizes System CTB, CSO, and SBS Specifications with Superior CNR Performance.
Flexibility: The Phase Modulation Technique of External Modulator maximizes the Input Fiber Power for Long Distance Transmission with Excellent System CSO Performance and field-adjustable SBS thresholds 16 For different network transmission.
Reliability: Adopts 19 "1U standard rack, built-in High-Performance Dual Switching Power Supply, can be hot back working under the Urben Network Voltage 90~255Vac, MS-Level Automatic Switching; Cabinet Cooling can be Automatic Temperature Control.
Intuitive: External Modulator and Laser are the most expensive components of the whole machine. The machine is equipped with Microprocessor External Modulator and Laser Working State Monitor, the Operating Parameters displayed by the Panel LCD Window.
Network Management: Option Status Monitoring Transponder to ensure that meet the National Standard and compatible with SCTE HMS and WEB standards, Network Monitoring Function can be achieved.
