| Description
(1) OPT-1550E-IF Optical Transmitter adopts high-linearity butterfly DFB laser which is externally modulated to transmit 47~862MHz and 960~2600MHz signal in a single fiber.
(2) Optical transmitter can be specified with ITU standard wavelength for DWDM system to extend and update the networks. It can be amplified by EDFA and EYDFA for huge FTTH system. It can be Compatible with any FTTx PON technology to realize the combination of CATV, DVB-S, Internet and FTTH.
(3) Optical Transmitter adopts 19” standard rack, the parameters of the machine is controlled by micro-processor, the status and fault alarm are displayed by the LCD in the front panel. Standard Ethernet port supports SNMP management. The built-in laser APC, ATC control circuit assures the long life of the laser and reliable work. SAT-IF adopts high-linearity IF driving circuit with AGC to ensure the high quality transmission of Analog TV, Digital TV (DBS-C, DBS-T) and Satellite TV in a single fiber
Features
(1) Both the external modulator and laser are imported from the United States or Japan.
(2) Perfect pre-distortion circuit ensures the best CTB and CSO when the CNR is in high standard.
(3) Perfect SBS suppress circuit and adjustable SBS, suitable for different types of CATV net.
(4) AGC control.
(5) Internal double power supply which can be switched automatically.
(6) Automatically shell temperature control.
(7) Internal microprocessor software has the function of laser monitoring, parameter display, fault, warning, and network management and so on. Once the working parameter of the laser goes out of the fixed value of the software, the machine will warn.
(8) The transmitter provides ETHERNT and CONSOLE standard interface for the connecting the computer.
(9) CATV and SAT-IF signal can be transmitted in a single fiber
(10) It can be amplified by EDFA and EYDFA, compatible with any FTTX PON technology
