1. Product Summary
1310nm AM direct modulated optical transmitter is the most important
equipment to construct the CATV HFC network. It mainly used for the long
distance optical fiber transmission of TV image signal, digital television signal,
telephone voice signal and data (or compressed data) signal. This product does
use the high-performance DFB laser as the optical source. The RF drive part
adopts RF power digital automatic processing technology and advanced RF
pre-distortion circuit, and built-in microcomputer automatic monitoring
system, to ensure the excellent performance indicators.
2. Performance characteristics
Adopt high-performance coaxial/butterfly DFB laser, narrow spectral lines,
good linearity and high output power.
■
The RF drive part adopts the RF power digital automatic processing
technology. Automatic processing the drive level power according to the RF
input signal level and the number of channels (15-84 channels), make the CSO,
CTB and C/N index always at the optimal value to ensure the overall
performance.
■
Advanced multi-frequency RF pre-distortion technology, combined with the
GaAs device, effectively improve the CATV system most important CTB and
CSO index, C/N index also gets the maximum upgrade.
■
Adopt advanced 32 bit processor; coordinate with perfect automatic
monitoring system circuit. It can timely and accurately monitor working status
of the laser to ensure a stable optical output power and effectively extend the
working life of the laser.
■
Built-in blue screen 160×32 dot matrix LCD monitor on the front panel,
accurately showing all working status parameters.
