Description
Overview
GAOTek fiber optical transmitter is a 1550 nm direct modulation optical transmitter with a high index and AGC function. It adopts high linearity and low chirp DFB laser, built-in pre-distortion compensation, and AGC, APC, and ATC closed loop control, which improves the system index. If working with the EDFA, there will be serious CSO deterioration. It can be used in towns where the fund is short, and the distance is less than 6.21 mi as a transition solution.
Features
- Low chirp, high linearity DFB laser, chirp compensation
- Full-automatic OMI control, AGC & MGC
- Dual module RF driver
- highly efficient laser pre-distortion adjustment
- Intuitionistic modulation select display
- Built-in dual backup power supply, switch automatically
- Casing temperature auto-control, ensures the long life of the laser
