Signals and data (or compressed data) signal long-distance optical fiber transmission. This product is used by international brand low-noise 1550nmDFB lasers, high-performance LiNbO3 external modulator, RF-driven part is
My company developed digital automatic processing of the RF power technology and advanced RF pre-distortion circuit, and built-in microcomputer automatically improve the monitoring system to ensure the excellent performance of the machine. This product
The performance products and advanced technology imported models with considerable; and good looks, excellent targets, cost-effective for large and medium-sized CATV fiber optic networks.
Features:
Used by international brands of high-performance DFB lasers and LiNbO3 external modulator, line narrow, linear, high output power; and increased advanced adjustable SBS control circuit, ensuring excellent light
Link targets.
RF-driven part of the company independently developed by the RF power digital automatic processing technology, according to the input level of the RF signal level, channel number (15 ~ 84 channels), automatic processing of radio
Frequency drive power, the CSO, CTB and C / N value is always in the best indicators to ensure that the overall performance, and to optical receiver output level constant.
Advanced multi-frequency RF pre-distortion technology, combined with GaAs devices, effectively improve the CATV system, the most important indicators of CTB and CSO, the C / N Index also the largest increase.
Built-in microcomputer automatic control circuit complete, accurate real-time monitoring laser output power and a variety of working conditions, ensure a stable optical output power, and effectively extend the working life of the laser.
Embedded in the front panel blue VFD display, accurate display of the work of state parameters and fault information, intuitive and clear.
19 "1U rack height, with a standard RS-485 and RS-232 network interface, can easily implement network monitoring.
