Analog DWDM Narrowcast Transmitter Selectable RF Gain, Channel 27; Fiber Optic DWDM Transmitter; 1GHz, 80Qam channel High RF Gain Transmitter module at ITU, for CH3000 Chassis.  10dB Output Power in single width module.  This particular model goes with backplate models BP-35M4K-1-00-AS(ch.23-27), 4 channel model, or BP-A4, single channel model.  Each of these backplate models are sold separately. Class 1M Laser Product, Quality Control;  This item is silver in color with gray on the faceplate.  It measures 1x5x13.

Class 1M Laser Product- Laser products considered Class 1M are, much like Class 1 lasers, safe and incapable of producing hazardous exposure. However, when viewed with collecting optics, such as a telescope, Class 1M lasers can potentially be hazardous. Otherwise, they are exempt from control measures.

Quality control (QC) is a process through which a business seeks to ensure that product quality is maintained or improved with either reduced or zero errors. Quality control involves testing of units and determining if they are within the specifications for the final product.

The AT3535G series high performance Analog Narrowcast Transmitters are a key element of Aurora Network’s Passive HFC architecture and are designed for Dense Wave Division Multiplexing (DWDM) applications for forward path transmission of narrowcast digital services. Each transmitter’s wavelength is specified at one of 40 wavelengths on the 100 GHz DWDM ITU grid (ITU-T G.694.1). AT3535G transmitters incorporate advanced predistortion circuitry to enable transmission of up to 80 QAM modulated channels per wavelength. Transmitter output power is 10 dBm for maximum network performance and application flexibility. 

These transmitters incorporate a user-selective (enable/disable) RF input gain stage to permit its use with lower RF input levels. As network segmentation increases, each source QAM signal must feed a larger number of QAM transmitters, with resulting RF losses due to the required splitting. Moreover, as each transmitter is able to handle greater numbers of QAM channels (up to 80), the required combining of the (previously split) individual source QAM signals will also result in higher RF losses. The user-selectable RF input gain stage provides compensation for these losses. 

The unique mid-plane packaging of the AT3535G features both a compact one-module-width design and an integrated “back plate” multiplexer which eliminates the need for a separate platform or shelf for a typically packaged multiplexer. This 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. 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.
