Node Platfor m Overview
STARLINE ® OPTICAL NODE
FEATURING 3X TDM DIGITAL RETURN TECHNOLOGY
Featuring 3X TDM Digital Return Technology
The Motorola Starline SG2000 is an 870 MHz enhanced Gallium
Arsenide (E-GaAs) optical node that delivers high performance and
rugged reliability. It provides four RF outputs and accommodates up to
three optical receivers and:
• Two analog return transmitters, or
• One 3X DWDM digital return transmitter, or
The SG2000 Optical Node sets the
industry standard for performance,
reliability, and value.
• One CWDM digital return transmitter
This full-featured optical node is available with optional ingress
control switches and a status monitoring transponder. The SG2000
supports redundant 60/90 volt powering and dual powering is also
available, enabling to accept two independent AC sources for
maxiumum reliability.
Currently rated to pass 15 amperes, the SG2000’s electronics chassis
implements ergonomic hot-swappable plug-ins for rapid replacement
in the field. Fully configured to meet specific system requirements, the
SG2000 is the answer in an expanding global market, as it fulfills the
latest demands of one-way and two-way broadband network
applications, including broadcast video, telephony, and data.
Forward Path
The SG2000 platform addresses split-band or redundancy
applications. A standard split-band configuration has analog signals in
the 52 to 550 MHz band feeding one receiver, while digital
transmissions or narrowcast signals are carried between 550 MHz and
860 MHz on another fiber and processed by the second receiver. If the
narrowcast receiver loses optical signal input, the optional third
receiver can serve as a backup, with an automatic path switchover
handled through status monitoring or manual control modules.
The SG2 receiver's integrated optical hybrid photo-detector improves
RF performance over the entire 52 to 870 MHz pass band. The
receiver is enabled and disabled in response to a signal from the
status monitoring transponder, providing excellent isolation,
reliability, and power consumption in redundant applications.
The optical power monitor circuit continually monitors the status of
the fiber link. An integrated optical bulkhead connector provides
superior fiber management and module link status indicators reduce
troubleshooting time. The module is fully compatible with the status
monitor transponder, allowing remote monitoring of module
and link performance.
Return Path
The node's dual return path analog optical transmitters offer
split-band or redundant functionality. In split-band applications, the
RF inputs from ports one and three are combined on one transmitter
and the RF inputs from ports two and four are combined onto a
second optical transmitter. When configured for redundancy, both
return lasers are active full-time, transmitting the combined RF
return signals. In the event of path failure, return path redundancy is
accomplished at the headend or receive site by switching to the
alternate fiber.

A full series of analog 1310 nm optical transmitters are available for
the SG2000 platform. This product series, packaged to include
connectors plus return path amplifiers, offer several advanced features. The SG2-IFPT/* transmitter uses an isolated Fabry-Perot laser
operating at 400 uW. The SG2-EIFPT/* transmitter uses an isolated
Fabry-Perot laser operating at 1 mW. The SG2-DFBT/* and DFBT3/*
use state-of-the-art uncooled, isolated, distributed feedback (DFB)
lasers operating at 1 mW and 2.0 mW respectively for improved link
performance. A new 1550 nm DFBT6/SC 4.0 mW uncooled, isolated
distributed feedback (DFB) laser is also available.
Redundant Powering Capability
Equipped with optional dual power supplies, the SG2000 offers complete system redundancy. The dual module DC power supplies are
located in the lid. Each DC power supply can deliver the total power
required by a fully configured node: 4.3 Amperes at +24 Volts and
0.69 Amperes at +5 volts.
All transmitters carry a full 35 MHz of digital data or up to two video
channels. The transmitters include thermal compensation circuitry to
reduce the changes in received optical and RF signal levels as the
node temperature varies. The transmitters are enabled and disabled
in response to a signal from the status monitoring transponder for
economical power consumption and enhanced reliability.
Motorola's high speed digital return transmitter, the SG2-DRT-3X is
an excellent solution for node segmentation and wavelength
aggregation issues. The SG2-DRT-3X Time Domain Multiplexing
(TDM) system allows optimum use of the available bandwidth per
subscriber by efficiently handling unbalanced distribution between
ports.
The multiple receiver functionality of the platform accommodates split band and/or redundancy applications.

When configured for redundancy, the dual power supplies are
connected through a load-sharing circuit, if either supply fails the
other will absorb the total load without system interruption. The
new platform meets the 90 volt requirements of advanced network systems by supporting 60/90 volt powering, which enables
the user to switch voltage supply.
Network Monitoring
Employing state-of-the-art network management, the status
monitoring transponder handles optical link, receiver, transmitter,
and RF electronics performance measurement control and alarm
generation. The status monitoring transponder is also an
effective tool to ensure system reliability. The status monitoring
circuitry oversees optical power, laser bias current, receiver
current, AC and DC voltages, temperature, lid tamper, forward
and reverse RF current, RF level, auto drive voltage, and RF
ingress switching control. The SG2000 is compatible with multiple status monitoring software vendors.
