1550nm Internal Modulation Optical Transmitter

                        (Model: LT1507)

 

 

Brief Introduction

  

1550nm Direct Modulated  optical transmitter uses 1550nm DFB laser as its light source.

Mainly used in the 20-25KM transmission of television signal, digital TV signal,

cable telephone and data signal, it is the important equipment in building large and

middle-scale CATV optical fiber network.

 

 

Feature

  

 

- Low chirp, high linearity DFB laser.

- Dual module RF driver, high efficient laser pre-distortion adjustment.

- Perfect APC, ATC closed loop control.

- Intuitionistic modulation status display.

- Built-in dual back-up power supply, switch automatically.

- Casing temperature auto-control, ensure the long life of the laser.
