The SG2000 Optical Node sets the

industry standard for performance,

reliability, and value.

HIGHLIGHTS:

• 870MHz E-GaAs performance

• Up to three optical receivers

• Up to two optical transmitters

• High speed digital return 3X technology

• HMS compliant status monitor transponder

• Hot-swap modules

• User-friendly fiber management

• Redundant powering capability

• 15A power passing

• Ingress control switches

• SC/APC and FC/APC connections

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.

SG2000 OPTICAL NODE

Node Platform Overview

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

• 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.
