ARRIS VTN‐ITU‐CH*

The ARRIS VTN‐ITU‐CH* transmitters feature cooled, 8 dBm Distributed Feedback (DFBT) lasers based on the International Telecommunications Union (ITU) wavelength grid. Without amplification, the typical link budget is 14 dB.When needed, the VTNITU‐CH* DWDM signals can be amplified by Erbium Doped Fiber Amplifiers (EDFA) to overcome large link budgets similar to digital return links. The VTN‐ITU‐CH* is supported by the VTN‐DOCSIS status monitor transponder. Parameters for control and monitoring include optical output power, laser bias current, and supply current.
