Product description

1. FWT-1550DT series of optical transmitter product is a new type of high-performance 1550nm CATV Optical Transmitter.

2. Transmitter is the 1U height, and can be easily installed in 19 "rack. The main devices adopt DFB low-noise, continuous-wave lasers with thermoelectric cooling device,such as AOI,XT, JDSU.

3. SMNP network control technology, the machine's technical performance indicators fully measure up the standard of similar imported equipment , It can provide high-quality images, digital or compressed digital signal long-distance transmission for cable television and telephone communications.

Features

1.  High quality: original system optimization control technology and RF pre-distortion technology ensure that the system can acquire the maximum CTB, CSO, and SBS targets in the case of excellent performance CNR . 2.  Flexibility: RF with AGC and MGC circuits to choose from, whether it is AGC or MGC , the output level can be adjusted within the effective range, only when the AGC state, when the input level is within the framework of the automatic control, the output will not change with the input. 3.  Reliability: The 19 "1U standard rack, built-in high-performance dual switching power supply,it can work in the backup at 85 ~ 265Vac City Network Voltage, MS-level automatic switching; chassis cooling automatic temperature control. 4.  Intuitive: The laser is the most expensive machine components, machine equipped with microprocessor monitors the working state of the laser, the panel LCD window displays the operating parameters. 5.  Network type: Select All-piece status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standard, it enable network management monitoring capabilities.
