SG2-DRT-3X
Installation Sheet 494828-001
This Installation Sheet describes the procedure for installing the SG2-DRT-3X in the SG2440 or
SG2000 node.
The Motorola
®
Digital Return Transmitter (SG2-DRT-3X) converts three independent 5 to
42 MHz analog RF return-path signals into one digital optical signal within the SG2000 and
SG2440 nodes. This digital optical signal, with 10-bit resolution and 3.1 Gbps rate, is suitable
for optical transmission to the GX2-DRR-3X Digital Return Receiver (DRR) where the original
analog return-path signals are recreated.
The transmitter is factory-configured with either a dense wave division multiplexing (DWDM)
laser on the International Telecommunications Union (ITU) grid or a coarse wave division
multiplexing (CWDM) laser that is applicable to the required link. Motorola provides standard
models that are identified in the subsection SG2-DRT-3X Models at the end of this document.
The specific wavelengths are stamped on the label of each transmitter.
An Automatic Power Control (APC) system regulates the optical output power from the laser.
The unit provides automatic gain control (AGC) and requires no adjustment. The SG2-DRT-3X
features alarm LEDs to report local status information.
To facilitate easy upgrades, the SG2-DRT-3X has the same set-up levels as the analog return
transmitters. The double-wide module occupies the same locations as the two analog
transmitters in the node lid. The SG2-DRT-3X generates its own 5 V power and works with a
single SG2-PS2 or SG2-PS power supply.

Before You Begin
Before you install the SG2-DRT-3X, verify that you have received the SG2-DRT-3X-CH*Kit,
part number 498284-TAB.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
