SOT-02 Optical Transmitters

SOT-02 Optical Transmitters are designed for operation in forward and return paths. The forward path transmitters are equipped with a DFB-laser of 1310 nm wavelength, what prevents high non-linear distortion in CATV networks. The return path transmitters can be implemented with one of the laser diodes (FP or DFB). The wavelength of the return path transmitter can be from 1470 to 1610 nm (for CWDM technology defined when ordered).

SOT-02 Return Path Optical Transmitter

SOT-02 Return Path Optical Transmitter

The Return Path Optical Transmitter is used for data transmission in the fiber-coaxial cable networks.
Key features:

  • Optical power check
  • Input level adjustment
  • Tap
  • Compact housing

It is recommended to use SOT-02 Return Path Optical Transmitter along with a forward path optical transmitter and a diplexer. The Optical Transmitter can be equipped with a DFB laser up to 3 mW.
