ATX-Innotrans HFC optical solutions

InnoTrans offers unique, multi-wavelength transmission solutions, offering a cost-effective alternative to replacing remote headends, optical node segmentation, and FTTH CATV overlay.

InnoTrans, with its unique and patented procedures, eliminates the "chirp" and laser clipping effects in case of direct modulated optical lasers. Due to these techniques and high linearity, a significantly higher optical modulation index and thus lower optical launch power levels can be achieved. The InnoTrans solution provides the same quality parameters as the external modulated 1550nm optical transmitters at a much better price.

With their offered solution, it is possible to transmit up to 40 full-band forward and 80 return channels on an optical fiber.

Chromadigm - Full band, multi-wavelength optical TX
TranScend Iso Front 1.jpg

Chromadigm's 1550nm multi-wavelength optical transmitter, featuring InnoTrans's unique patented techniques, delivers the same quality parameters as external modulated optical transmitters at a much more affordable price. In case of the conventional direct modulated optical lasers the so-called "chirp" distortion and linearity issues are the main problems. InnoTrans eliminates these limitations. Up to 40 different wavelength full-band forward signals can be transmitted on an optical fiber (In case of more than 4 wavelengths configurations, 16 wavelengths can be inserted into the 2RU modular ChromaFlex frame).

Product Features:

  • ​The 1RU Compact Product Version may contain the maximum of 4 optical transmitters, an integrated EDFA unit and optical passives

  • Up to 4 different wavelengths in one unit

  • CIR product version optimized for FTTH applications with 1 wavelength and optional optical amplifier

  • Up to + 18dBm output optical power

  • Any combination of analog and digital channels

  • Outstanding CNR, CSO and CTB

  • Error-free QAM signal transmission due to high OMI

  • Distance independent transmission parameters

  • Optional integrated Express port for additional wavelength reception

  • 4-40 wavelength transmission on an optical fiber, depending on distance and channel allocation
