AT3550 Series
Analog 1550nm Broadcast Transmitters (1 GHz) |
The Aurora AT3550 series high performance 1550nm 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, including broadcast center
wavelengths at 1545.3nm or 1563.0nm, 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 256QAM 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.
