1550nm External Modulated Optical Transmitter
Overview:
SPC-OT15 series 1550nm optical transmitter is designed for 750MHz or 862 MHz optical transport systems, especially for CATV system. The high performance, reliable optical transmitter help you meet the demands of today's advanced broadband networks.
Feature:
High quality, high linearity DFB laser
Advanced pre-distoration function
1U, 19 inch standard chassis,220V AC, 50Hz switching power supply or others.
750 or 862 MHz bandwidth, supporting most broadband transport application
Unique thermal design provides superior heat dissipation, increasing the reliablity of your system
Automatic gain control helps maintain constant RF drive level to laser of consistent performance
An interface LCD display allow you to monitor the transmitter's performance. In addtion, RS 232 helps you monitor your transmitter performance in a long-distance.
