SG4-DRT-2X

The SG4-DRT-2X uses 10-bit A/D technology to double the return bandwidth

capacity and allows system operators to segment Starline

SG4000

node locations. The 2X Time Domain Multiplexing (TDM) system

enables you to split the node return path traffic in half, treating each

half as a separate return path stream. Both streams are combined on a

single transmitter for optimum utilization of fiber. You can also install

an additional transmitter to provide equipment and path redundancy.

The SG4-DRT-2X transmitter module uses a state-of-the-art isolated,

cooled, Distributed Feedback (DFB) laser for improved link performance.

These transmitters use lasers based on the International

Telecommunications Union (ITU) frequency grid plan spaced at 100 GHz.

The system is completely scalable and can be expanded from a single

transmitter/receiver to groups of 4, 8, 16, or 32 wavelengths over a

single fiber with the use of muxing and demuxing equipment. The system

is compatible with Motorola low noise optical amplifiers (EDFAs),

allowing network designs that cover large geographical areas. Without

amplification, the Motorola 2X DWDM digital return system is capable

of achieving a link loss budget of 26 dB.

Each module accepts two unique 5-65 MHz return signals at its input.

Each input is digitized with a high-speed A/D converter and then

converted into a 3.1Gbps TDM data stream that drives the laser. The

optical detector, together with the demultiplexer, decoder, and amplifier

are contained in the Omnistar

GX2-DRR-2X digital return receiver.

With the implementation of time division

multiplexing, Motorola’s 2X digital return

simplifies node segmentation in the

Starline

SG4000.

BENEFITS INCLUDE:

• 5-65 MHz Return Path Operation

• High optical output power +8 dBm

• Excellent noise power ratio (NPR) 40/11

• Easy upgrade path for node segmentation

• 40 DWDM wavelengths available

• Downloadable firmware

• Plug-n-Play installation and operation

The SG2-DRT-2X features an enable/fault LED to report local status

information. An integrated optical bulkhead connector provides simple,

quick-connect module installation and facilitates easy connector

cleaning. All necessary cables required to install the SG4-DRT-2X in

SG4000 nodes are included with every transmitter.

To facilitate easy upgrades, the SG4-DRT-2X has the same set-up

levels as the analog return transmitters. The double-wide module

occupies the same locations as two analog transmitters in the node

lid.
