Product Description
The 1550nm external modulated optical transmitter is the highest-class product. Adopt Narrow line width（Typ.=0.3MHz） and Low-noise imported DFB laser as the source; Adopt high linear LiNbO3 external modulator as RF signal modulator, with special CTB, CSO, dual high-frequency SBS threshold control, etc. core technologies; designed for long-distance transmission networks.
The 1550 series external modulation optical transmitter is the first choice product for networking broadband transmission systems and large-capacity CATV optical transmission systems. It is applied to optical modulation, optical insertion, WDM, and related network upgrades and expansion of a large 1550nm optical transmission system. It is the core equipment for the RFTV radio network system to realize Triple-play, FTTH, and 1550nm systems.
Feature
1. Multi-configuration for customization: The finely differentiated specifications can meet the requirements of different networks, with single output and double outputs, and output optical power can be chosen from 3dBm to 10dBm.
2. High-performance laser: The DFB laser with narrow line width and low noise as the light source and the LiNbO3 external modulator is the external signal modulator.
3. Pre-distortion circuit: Superior pre-distortion circuit, with perfect CTB and CSO performance when CNR is high.
4. SBS suppression circuit: Superior SBS suppression circuit, SBS continuously adjustable, can be suitable for different transmission distance network demands.
5. AGC control: Automatic gain control(AGC) to maintain stable signal output when different RF inputs.
6. Dual power supply guarantee: Built-in dual power backup, support hot*plug, automatic switch.
7. Full automatic temperature control: Auto chassis temperature control; intelligent fans when the case's temperature up to 30 ℃ begins to run.
8. Display and alarm: LCD display, with laser monitoring, digital display, fault warning, network management, and other functions; Once the working parameters of the laser deviate from the allowable range set by the software, the alarm will be prompted.
9. Overall network management function: The standard RJ45 interface, supports SNMP, remote network management for the computer, and adjustment of AGC, SBS, OMI, etc., can also change the model and serial number displayed on the front panel, the local network management, and monitoring.
