Our company carries on the innovation to the existing technology, thus expands the production scale unceasingly to obtain the bigger profit.
1550nm Outdoor Laser Optical Transmitters is applied in the multi-channel transmission, the laser’s chirp effect will react with the link dispersion of the fiber. There will be distortion on the receiver. If working with the EDFA, there will be serious CSO deterioration. The distortion and deterioration will increase with the longer distance and more channels.
1550nm internal modulation CATV optic transmitter, has the chirp and dispersion compensation inside, and improves the system index greatly. It can be used in the town where the fund is shortage and the distance is less than 10Km as a transition solution.
Features
Low chirp effect, high linearity DFB laser
Dual Module therefore drive, chirp compensation Laser OMI AGC/MGC
Intuitional modulation status display
Dual power supply inside backup. Full-automatically swicth Full-automatically control of casing temperature
