Product Description

FWT-1550DT Series 1550 nm Advanced Type Directly Modulated Optical Transmitters

Product Description
FWT-1550DT series of advanced 1550nm directly modulated optical transmitter, is mainly used in overlay insert systems to implement high-value and multi-functional local designed value-added services such as self-run programs. Low chirp, the output is the ITU standard wavelength, the RF driver adopts a self-developed RF predistortion circuit and a built-in perfect microcomputer automatic monitoring system to ensure the excellent performance index of the device.

FWT-1550DT series of advanced 1550nm directly modulated optical transmitter, suitable for 10 ~ 20 kilometers long distance transmission.

Product feature
1. Top quality: The low chirp, high linearity DFB laser, and RF pre-correction circuit are used to keep the C / CTB, C / CSO, and C / N indexes in the best state.
2. Transmission range: 10 ~ 20 kilometers for short distance transmission.
3. Reliability: 19" 1U standard rack, built-in high-performance 1 + 1 hot backup power supply, which can work at 86 ~ 265Vac city network. MS automatic switching, and chassis temperature automatic control.
4. Excellent performance-price ratio: suitable for FTTH triple play CATV from headend to end user.
5. Intuitive: The laser is the most expensive component of the device. The built-in microprocessor software monitors the working status of the laser, and the working parameters are displayed on the panel LCD.
6. Network management type: SNMP network management, can realize the network management WEB monitoring function.
7. Can be customized 2 outputs, optical power 5 ~ 6dBm output.
