Product Introduction

Our company has strong technical force, complete detection means and our Dual Mode WiFi XPON ONU, 4GE+Dual-frequency WIFI ONU, Outdoor Modular Optical Node quality is well-known in the same industry. We build a platform for the common development of enterprises and employees to make their lives happier. We take innovating value for customers as the mission of our enterprise and judge our work by whether we can innovate value for customers We understand that acting with integrity is essential to building and maintaining mutual trust and good relationships.

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.

15503

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
