Deployed in the national telecommunication infrastructure network
WDM is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e. colors) of laser light. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity. Within this scope, following features can be taken into account:
The focus of this project contains twofold :
Anticipated steps to achieve the following strategic objectives:
The project provides a unique opportunity to acquire knowledge and hands-on experience (both hardware and software design) on the 2.5Gbps SDH technology. The accumulated experience can be utilized to devise systems that fulfill prospective customers' needs.
Optical networks play an increasingly important role in the transmission of information in modern telecommunication arena. Therefore to pursue this trend in Iran, ICT research Institute is initiating the development of three prototypes of STM-16 optical multiplexer systems for multiplexing four STM-4 level optical signal with the following features:
The proposed STM project comprises three phases which will begin following completion of the feasibility study:
• Multiplexing of four STM-4 optical input signals into one STM-16 optical signal & De-multiplexing on the reverse side
• Customizing our prototype design to comply with the (ITU-T) standards and to fulfill requirements for national optical-based transmission network , then passing the know-how and experience down to domestic manufacturers
• Building on the knowledge and expertise, moving to the next step of developing world class STM-16 products aimed for the overseas market
Construction of test interfaces for up to 100Gbps optical transmission systems
Preparation of testing procedures (manual) for up to 100G optical transmission equipment includes:
oEthernet interfaces & substrates MAC / IP & PCS parameters
oETH over TDM
o (All) optical parameters
o (the) timing section
oSDH section
ovalidated guidelines
Creation of testing documentation for the reference type approval laboratory
This project sets up a laboratory for testing high-capacity optical transmission network equipment and devices at up to 100Gbps rate. The facility will be responsible for checking performance as well as for verifying adherence of their specifications to the global ITU-T standard. The main features of this assignment are:
Within this scope, following features can be taken into account:
In the fifth national development plan, the necessity of setting up reference type approval Labs in the field of communications & information technology is stipulated. And, this is further emphasized by the fact that the access section of the National Information Network will be largely based on the GPON optical technology. Therefore, an important outcome of this assignment is to identify the highest quality systems and components for incorporation into the national fiber network.
Sharing our accumulated experiences with the relevant academic faculties, transferring the know-how to domestic optical equipment manufacturers on standard-adherent products and backbone operators as well as providing advisory services to the regulatory authorities.
The aim is to establish a type approval facility to carry out verification tests on all submitted sample optical access systems and products in order to verify compatibility with global ITU-T standards. The testing procedure involves equipment performance checks and design specification measurements as well as field checks of sample systems, network, etc. to establish compliance with the relevant ITU-T protocols.
The project also calls for the procurement of the highest quality instrumentation, including measurement tools, evaluation and calibration equipment, etc., as well as for provision of comprehensivedocumentation on set up & test procedure
Within this scope, following peculiarities can be taken into account:
NMS is an innovative software system for enterprise LAN management. It can find manageable nodes and all their subsets as well as perform effective management and monitoring of these nodes. This system periodically collects node status and information while displaying raw and analytical results.
Within this scope, following peculiarities can be taken into account:
Given the growing world trend towards IP-based multimedia communications and the desire for every country to introduce its own native and customized model, proper evaluation of IP- based equipment for final type-approval is a major issue for the regulatory bodies. NGSTAP's objective is to develop a central and reference platform to accommodate all types of (or a variety of) evaluation scenarios. Test operators affiliated to different entities including government organizations, industry, research institutes, etc. can be connected to the platform and create their desired test procedures. This versatile reference platform is beneficial to the next generation system developers, importers and operators to enable them to achieve the highest quality of service.
NGSTAP is a type approval system that can be employed for performance and functional testing. It is a service oriented platform which finds application in test and type approval projects to develop some tests independently and in parallel. This platform consists of various modules for definition, creation, running, monitoring and reporting of the different test scenarios and has been designed based on IMS model and with a look to the future.
NGSTAP architecture has been designed with a service oriented approach which offers services for test scenario design, test scenario creation, test scenario run and preparation of reports. Test scenarios are protocol independent and system runs them according to the selected protocol. The following are the main technical specifications can be mentioned in this regards:
