The Aurora AT3550 series high performance 1550 nm externally modulated analog transmitters are available in several optional configurations to meet various network requirements and feature minimum output power of 9.5 dBm with 14 to 18 dBm SBS suppression. The compact design minimizes rack space requirements and permits plugging the three-slot-wide, full-depth transmitter module in either the front or rear of the CH3000 3RU chassis to optimize equipment installation and operating conditions.

Several wavelength options are available, to include broadcast center wavelengths at 1545.3 nm or 1563.0 nm, or channel selection on the DWDM ITU-grid (ITU-T G.694.1).

The characteristics of the transmitter's source laser allow high carrier-to-noise ratio (CNR) while the proprietary predistortion circuit that drives the optical modulator provides excellent CSO and CTB performance, with 450 MHz of digital channel loading 6 dB below the analog channels. AT3550 series transmitters are digital ready, and can be fully loaded with 100% digital 256-QAM signals. This family of transmitters is part of the full complement of products developed by Aurora Networks to support and enhance the deployment of traditional HFC, passive HFC and fiber-to-the-home (FTTH) networks.
