PRODUCT OVERVIEW
The ARRIS AT3552H C-band externally modulated analog transmitters support 1.218 GHz bandwidth operation for DOCSIS
®
3.1
applications. These models provide high SBS suppression optimum for high launch powers into optical fiber for enhanced HFC, RFoG,
PON, and FTTH applications.

Dual RF input ports allow combining of separate broadcast and narrowcast inputs within the transmitter to simplify deployment in
the head end. AGC circuitry compensates for variations in the RF input level to the transmitter to maintain
a
constant RF drive
level to the laser.
The characteristics of the transmitter’s
optical
source allow high carrier-to-noise ratio (CNR) while the proprietary pre-distortion
circuit provides excellent CSO,
CTB, BER, and MER
performance. AT3552H series transmitters are digital ready and can be fully
loaded with 100%
QAM/OFDM
signals.
The compact design minimizes rack space requirements and permits plugging the one-slot-wide, full-depth transmitter module in
either the front or rear of a CH3000 3-rack unit size chassis to optimize equipment installation and operating conditions. This
family of transmitters is part of the full complement of products developed by ARRIS to support and enhance the deployment of
HFC, RFoG, and fiber-to-the-home (FTTH) networks.
Several wavelength options are available on the DWDM ITU grid (ITU-T G.694.1).
