Test new services

Quickly identify and fix faults

Foresee fiber degradation

In addition to this proposal, ShinewayTech will be presenting further details of our solution and explore how we can be of assistance in SHINEWAYTECH.

 

1.2  Solution Summary

1.2.1       Advantages of the FiberWatcher Solution

To summarize, the proposed solution from ShinewayTech offers the following advantages:

Expand the system to accommodate in-service monitoring system.

Modular and hot-swap hardware design to reduce the maintenance cost.

Up to 128 optical ports on the RTU, and up to 384 optical ports with an external OTAU.

Easy web interface access.

 

        FiberWatcher Remote Fiber Test System is an intelligent system developed to meet the requirements of maintaining and managing a optical fiber network. It is powerful in function, convenient to operate, strong in expandability and easy to install and maintain.

        Besides performing 24-hour monitoring over the optical fiber network to get detail optical fiber information and locate faults, FiberWatcher provides varieties of testing modes for active or dark fiber and on-demand or scheduled test.

        In addition to the varieties of testing and analyzing functions, Geographic Information System (GIS) interface, and optical fiber testing and alarm locating, FiberWatcher is also able to provide management and statistical analysis of resources in the optical fiber network by combining the powerful functions of Oracle database. Therefore, it can help senior managers comprehensively master the status of the optical fiber network and intelligently make relevant decisions.

        With the design of embedded operation system and compact module, FiberWatcher is highly stable and convenient to expand and maintain. FiberWatcher offer a complete, stable, and powerful fiber testing system to shorten the optical fiber’s fault time and improve the QoS.

 

1.2.2       Test System Controller (TSC) 

     TSC is the data collection and analysis center of FiberWatcher, and is also the management center of the whole monitoring system. The TSC central monitoring station can manage and test all Remote Test Units (RTU). In order to facilitate the operations of maintenance, TSC also provides remote access and onsite monitoring platforms. Each TSC can monitor the optical fiber status and is also able to designate testing and statistics. The operator can adjust the system settings according to specific requirements.

 

1.2.3       Remote Test Unit (RTU)

 

Remote Test Unit is a monitoring device integrating with hot-swap controller, optional redundant power module, OTDR, optical switch, WDM/filter, optical power meter, and powerful system software.

RTU can be flexibly configured with different hardware modules to meet various monitoring purposes. RTU can conduct 24-hour monitoring of optical fibers and record data for comparison of reference parameters. When a fault occurs, RTU will automatically analyze and feed back to TSC. Meanwhile staff can perform relevant testing and maintenance for the RTU through TSC.

The optical switch ports are connected to individual fibers for measurement. The OPM can measure the periodical optical power attenuation and foresee the degradation.

 

High stability – embedded operation system

Complete system functionalities – modular hardware for various test purpose

Monitor module status, version, serial number, and production date from TSC

1.2.4       Optical Test Access Unit (OTAU)

The OTAU is second tier of RTU, and thru OTAR the user can switch the test fiber link remotely. OTAU integrates the master control unit, power module, optical switch, WDM/filter, and optical power meter.

 

1.2.5       Communication Network

     FiberWatcher uses TCP/IP as its main communication protocol.

      Remote Test Unit (RTU) has a RS-232 interface and the TELNET network interface of CIT (Craft Interface Terminal) control solution, facilitating the project staff check of the complete device status; RTU can connect with network management center via IP network; when data communication using TCP / IP protocol, to ensure the network devices’ communication. It supports concurrent TCP connections and supports multiple simultaneous alarms.
