WS-50LTxxx series external-type optical transmitter is based on 1550nm direct-type optical transmitter developed, with high performance, high reliability and excellent cost performance, widely used in large and medium-sized CATV and distribution network, and WDM System and CFG dispersion compensation system. It’s to build large and medium-sized CATV optical fiber transmission network of important equipment.
Depending on the modulator, the transmission distance is slightly different. WS-50LTxxA series focus on product costs, is the economy outside the modulation transmitter. Using JDSU single-fiber modulator to meet the user point-to-point transmission, SBS value can be controlled at 16dBm, (analog signal transmission> 50km, digital signal> 75km) requirements, can be a long distance after zoom, is the branch of the secondary service area 1550nm optical transmitter ideal.

1.Adopt 32-bit high-performance ARM processor, with the perfect automatic monitoring system circuit. Real-time accurate monitoring of optical output power and laser various working conditions. Ensure stable optical output power. To ensure that the laser is in the best working environment.
2.Using a new generation of "wind swing" mode of work modulator phase system, the control process more accurate and fast, the modulator for a wider temperature range.
3.Using the CPU programming control of the microwave source, frequency, signal amplitude dynamic adjustable. Can produce arbitrary frequency and amplitude of the microwave signal, less harmonics. SBS threshold range 13-16dBm.
4.The working bandwidth 47 ~ 1000MHz.
5.19-inch 1U standard rack, the front panel embedded blue and white 144 * 32 dot matrix LCD display, can accurately display the equipment of the working parameters and fault information, and with the national standard Class II transponder, through the network to achieve network management monitor.
6.Plug-in dual power, 48V/220V optional
7.RF signal NC predistortion system, according to the number of signal channels and modulation amplitude accurately match the pre-distortion content, to ensure signal quality.
8.Narrow line width (1MHz), low noise, DFB continuous wave laser. LiNBo3 external modulator for signal modulation. To ensure that the system COS performance of excellent circumstances to improve the fiber into the optical power, increase the transmission distance.
9.RF gain optional AGC / MGC mode, OMI ± 7dB adjustable range.
