2G6 Directly Modulated 1550nm Optical CATV SAT TV Transmitter

Product Overview

Description

Description

1.  OPT-2600DB-U series Optical Transmitter adopts high-linearity butterfly DFB laser which is directly modulated to transmit 47-862MHz and 960~2600MHz signal in a single fiber.

2.  OPT-2600DB-U 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 large-sized FTTH system. It can be compatible with FTTx PON technology to realize the combination of CATV, DVB-S, Internet and FTTH.

3.  It adopts 19” standard rack, the parameters of the machine are controlled by micro-processor, the status and fault alarm are displayed by the LCD in the front panel. Standard RJ 45 supports SNMP management. The built-in laser APC, ATC control circuit assures the long life of the laser and reliable operation.

4. 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)   Adopt low noise DFB laser.

(2)   Superior pre-distortion circuit design, in achieving high standards of CNR value, perfect CTB and CSO performance value.

(3)   Intelligent fan, it began to run when the chassis temperature reaches the set 32 ~ 35℃.

(4)   AGC control, so that different RF input level can still maintain a considerable output performance.

(5)   VFD or LED display, with laser monitoring, digital display, fault alarm, network management and other               functions; once the laser operating parameters deviate from the software set allowable range, will alert.

(6)   With standard RS232 interface for local network management and monitoring of computers.

(7)   With standard RJ45 interface support SNMP for remote monitoring.

(8)   High-quality switching power supply, can be 90V ~ 265V AC or -48V DC work.

(9)   Single input with frequency 47~2600MHz.

(10) CATV and SAT-IF signal can be transmitted in a single fiber

(11) It can be amplified by EDFA and EYDFA, compatible with any FTTX PON technology
