Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

As operators migrate to architectures with deeper fiber reach, there is an increased need for flexible design options and efficient fiber utilization in the optical network. The Model GS7000 Optical Hub addresses those needs by providing multiple options for optical amplification, filtering, splitting, and combining, all in a field-proven Model GS7000 station.

Figure 1.           

Model GS7000 Optical Hub

The Model GS7000 Optical Hub employs a modular approach, allowing full configuration flexibility combined with simple component installation and removal. The Model GS7000 active optical modules include a variety of low-noise EDFA optical amplifiers for both broadcast and narrowcast applications, as well as optical switches that enable redundancy.

The Model GS7000 passive optical modules include single-function modules such as CWDM and DWDM 1x8 mux/demux’s, two and four band mux/demux’s, and a variety of optical splitters. Multi-function passive modules are also available, including combiners with integrated multiplexers and demultiplexers for narrowcast/broadcast overlays. The passive optical modules with higher input/output fiber counts make use of a multi-fiber ribbon cable which simplifies internal fiber routing and connectivity.

A fully configured Model GS7000 Optical Hub can combine narrowcast/broadcast using up to 64 wavelengths, providing forward and reverse optical paths for a total of 32 nodes. The station utilizes the same field-proven housing and dual internal power supplies as the widely deployed Model GS7000 4-Port Node.

Features

     EDFA modules for optical amplification

     Optical switch modules for redundancy

     Flexible and scalable optical passive modules

     Fiber management tray and tracks provide easy fiber routing and access to fiber connections

     Status monitor/Local control module for remote monitoring and control (Transmission Network Control System [TNCS] or other compatible element management system required)

     Fiber entry ports on both ends of housing lid

     AC power entry ports on both ends of the housing base

     Primary and redundant power supplies with passive load sharing

     Dual/Split AC powering

Benefits

     Eliminates building costs and permitting issues for new “brick and mortar” hub locations.

     Reduces the need for new fiber installation.

     Fiber management and fiber coupling (mux/demux, etc.) are typically done at the headend or hub, or within strand-mounted splice enclosures. This can now be done with the Model GS7000 Optical Hub.

     All passive devices are enclosed within the housing. No need for external splice enclosures.

     Optical amplification is typically done at the headend or hub, or with strand-mounted optical amplifiers. This can now be done with the Model GS7000 Optical Hub.

     The ability to add redundancy, or enable network switching for survivability is typically done at the headend or hub. This can now be done with the Model GS7000 Optical Hub.

Notes:

2. Insertion loss of module with 0.25 dB loss per mated connector pair for a total connector loss of 0.5 dB. Actual connection loss may be less or more depending on mating connector compatibility.

Status Monitor Transponder/Local Control Modules

Overview

A Local Control Module must be installed to allow local monitoring and control of the active modules in the Model GS7000 Optical Hub. For remote monitoring and control, a Status Monitor Transponder must also be installed. The Status Monitor (SM) Transponder connects directly to the Local Control Module (LCM).

Local Control Module

The LCM provides local monitoring and control capability at the Model GS7000 Optical Hub station. The LCM is equipped with a USB port to enable connection to a local PC/laptop. The Model GS7000 ViewPort software must be installed on the PC/laptop to allow all parameters monitored by the LCM to be displayed and to allow local control of the optical switches and optical amplifiers.

Status Monitor Transponder

The SM Transponder is HMS compliant and provides remote monitoring and control capability at the cable plant's headend. The Model GS7000 Optical Hub must be connected to an active two-way RF network for status monitoring communications. Configuration parameters for the transponder module, such as IP address, can be changed using the PC-based ViewPort software.
