InnoTrans Communications will demonstrate its Flexible Optical Network offerings at the upcoming CableLabs Summer Conference to be held in Keystone, Colo. August 15-17. InnoTrans, founded by the technical team behind Synchronous, will demonstrate how its Chromadigm 1550 DWDM solutions can be initially deployed for node splitting and fiber reclamation, and then converting to a fiber deep or RFoG solution without taking down the existing network even momentarily.

Fiber deep infrastructure solutions deploy fiber deeper into the access network, enabling cable operators to easily segment nodes and cost effectively add additional capacity to more effectively compete with carriers and satellite service providers. RFoG solutions, or RF over glass, was developed by the SCTE in order to help cable operators run fiber closer to homes without swapping out customer premises equipment (CPE) or making any changes to headends and provisioning systems.

The Chromadigm solution has the following features:

  • Provides distance independent performance, crucial for RFoG and fiber deep projects, which may have receivers at varying distances from the transmitter.
  • Operates in the C-Band on ITU wavelengths, which can be amplified in the field or in the hub to overcome network losses, unlike O-Band solutions, which have limited reach.
  • Has SBS suppression built in so that high powers can be launched into the fiber, unlike current direct modulation transmitters.
  • Has highest OMI, essential for RFoG products since a low modulation depth produces very poor carrier to noise ratios.
  • Ability to scale to 16 wavelengths in the future, providing a future proof building clock to keep HFC networks at the forefront of bandwidth delivery in the access market.
  • Has Integrated Optical Muxes and EDFA’s, minimizing the need for numerous optical jumpers in the headend.

“The Chromadigm forward path DWDM solution is being widely adopted by the MSO community in US and Canada,” said Mani Ramachandran, InnoTrans CEO, in a statement. “The solution provides operators the ability to do full four way node segmentation in both forward and reverse directions on one fiber, for distances up to 50 km.”
