The forward path of the GS7000 Node can be deployed with a broadcast 1310/1550
nm optical receiver with common services distributed to either four output ports (all
high level) or six output ports (two high level and four lower level). The forward
path can also be segmented by using one optical receiver that feeds all output ports,
two independent optical receivers that each feed half of the node’s output ports
(left/right segmentation) or four independent optical receivers that feed four
independent forward paths. Forward optical path redundancy is supported via the
use of optional local control module. The type of forward segmentation and/or
redundancy is determined by the type of RF amplifier assembly and Forward
Configuration Module installed in the node.
The GS7000 Node’s reverse path is equally flexible. Reverse traffic can be segmented
or combined and routed to up to four FP or DFB reverse optical transmitters, or to
two advanced Baseband Digital Reverse optical transmitters as part of our bdr
nm optical receiver with common services distributed to either four output ports (all
high level) or six output ports (two high level and four lower level). The forward
path can also be segmented by using one optical receiver that feeds all output ports,

The GS7000 Node’s reverse path is equally flexible. Reverse traffic can be segmented
or combined and routed to up to four FP or DFB reverse optical transmitters, or to
two advanced Baseband Digital Reverse optical transmitters as part of our bdr
™
system. Redundant (back-up) transmitters may be utilized. In addition, an auxiliary
input path is provided for reverse signal injection (5 - 210 MHz). Reverse
segmentation and/or redundancy are determined by the type of Reverse
Configuration Module installed in the node.
The GS7000 Node accepts Optical Transmitter Modules based on the existing
694x/GainMaker optical transmitters. Reverse optical transmitters can be installed to
transmit data, video, or both. Reverse bandwidth is determined by the diplex filter
and the reverse amplifier assembly. Diplex filter choices are 40 MHz, 42 MHz, 55
MHz, 65 MHz or 85 MHz.
The GS7000 Node utilizes new transmitter and receiver module covers that have
been designed to allow fiber pigtails storage within them, providing improved fiber
management within the node.
Up to four optical receivers and up to four analog or two digital transmitters can be
installed in the GS7000 Node.
45 - 90 V AC input power is converted to +24.5, +8.5, -6.0, and +5.5 V DC by an
internal power supply to power the GS7000 Node.

Hub Node
The GS7000 Hub Node performs the same functions as the GS7000 Node with the
added benefit of also providing optical gain and optical switching capability. The
hub node allows you to push fiber deeper into your network while taking advantage
of the RF plant that is already in place.
The GS7000 Node can be upgraded to a GS7000 Hub Node in the field. This is
accomplished by the installation of optical amplification (EDFA) modules, optical
switching modules, and the Status Monitor/Local Control Module in the node lid.
The GS7000 Hub Node can then serve as a traditional node feeding the local HFC
plant and as an optical hub with the optical amplifiers. The node hub with the
amplifiers can service up to 32 nodes at a distance of 50 km with only three fibers.
EDFAs are available in 17 dBm, 20 dBm, and 22 dBm for broadcast constant output
power. A 17 dBm or 20 dBm narrowcast constant gain EDFA version is available to
fit any architecture for requirements like DWDM narrowcasting.
