AT3300G Series
Analog 1310nm Transmitters (1 GHz) |
The Aurora AT3300G series 1 GHz 1310nm Transmitters provide increased
bandwidth capacity for the expanding service demands of HDTV, VoIP, VOD and high speed
DOCSIS. These transmitters are ideal for broadcast and narrowcast applications for
optical transport and are offered in four series of models: (1) AT33xxG-N-1 transmitters
(''standard'' performance models with a single RF input), (2) AT33xxG-N-2 transmitters
(''standard'' performance models with dual RF inputs), (3) AT33xxG-A-2 transmitters
(''standard'' performance models with dual RF inputs and AGC circuitry), and (4)
AT33xxG-E-1 transmitters (''enhanced'' performance models with a single RF input).
The AT3300G series transmitters with ''standard'' performance are available,
as noted above, with either a single 46 to 1002 MHz RF input or a dual RF input version
for combining separate broadcast and narrowcast inputs within the transmitter, while
the dual input version is designed to provide 50 dB isolation between the narrowcast
and broadcast inputs to protect against NC crosstalk on adjacent transmitters via the
RF drive network. An AGC option, available for the dual input version, compensates for
variations in the RF input level to the transmitter to maintain constant transmitter
output RF drive level to the laser.
All AT3300G series transmitters with ''standard'' performance are offered
in different models with link losses ranging from 3 to 12 dB, while transmitters with
''enhanced'' performance are offered in different models with link losses ranging from
3 to 15 dB.
High density packaging enables network operators to install up to 14
transmitters per 3RU chassis, all of which can be monitored remotely or locally from
the power supply module. Additionally, the compact single-width module design can be
plugged in either the front or rear of the CH3000 3RU chassis to optimize equipment
installation and operating conditions.
The compact design minimizes rack space requirements in headends or hubs
and enhances deployment of traditional HFC, passive HFC and fiber to the home (FTTH)
networks.
