(Dark Fiber), and real-time test. Moreover, The FIS2000 executes multiple test analyses,
offers GIS to do fiber test and alarm location. The functions of cable management and analysis
assist the administrator to fully understand cable status. Referring to scalability and stability,
the FIS2000 adopts modular design, which facilitates future expansion. Also, all its modules
and components feature high stability. Its very easy to install, operate, and maintain the
FIS2000.

4 Test on the Fibers
The FIS2000 offers two testing structures, off-line testing and on-line testing. The off-line
testing uses the dark fiber for testing, while the on-line testing uses the active fiber for testing.FIS2000 has real-time alarm function in order to test fiber and report the result to related
personnel immediately when fiber-break or aging. System can store the information of alarm
time , alarm date, alarm status and so on to save the maintenance time and manpower.
4.1 Testing Structure
1. Off-line Real-time Testing
The OTDR is testing on the dark fiber. However, through the PMU and LSU
configuration, still the operator can receive the alarming message within very short
period when the fiber got cut. This is the most cost effective way for the real-time
testing.
2. On-line Real-time Testing
The OTDR is testing on the active fiber. And together with the PMU and LSU, the
operator can receives the alarming message. The On-line mode provides more
accuracy and shorter responsive time than the Off-line testing mode.
4.2 Testing Type
System offers 4 types of test functions, regular test, daily test, on-demand test and
real-time test.
1. Regular Test
Regular testing function is automatically performed by RTU. RTU will test fiber
regularly according to the users period setting.
Regular test has the following features:
Auto-testing dark fiber or active fiber without affecting transmission.
Setting up test core ID, core number, test schedule, and record time.
Comparing test result and original trace reference.
Querying the conditions of every core and the system, offering hardcopy.
Auto-triggering alarm and offering hardcopy.

2. Daily Test
RTU will do daily test according to the users date setting, and will record test result
and trace. System will save the test trace accordingly for the users analysis and
comparison.
2. On-demand Test
System offers the function of on-demand test. While necessary, TSC can command
RTUs or WS through TSC to measure the optical performance of specified fiber,
RTUs shall offer the measurement result. This function can allow the user to test any
particular fiber they want, meanwhile the system will temporaily stop the regular test
and perform the on-demand test immediately(real-time). After finishing the test,
RTUs shall offer the measurement result immediately. Meanwhile, the regular test
status can be recovered immediately. This function wont affect transmission quality.
Besides, the user can compare test result and reference data.
3. Real-Time Alarm Test
When the TSC receives real time alarm from RTUs, it shall command RTUs to
measure optical performance of monitored channel to find out the factor and location
of failure.
After RTUs start up, they shall automatically run real time testing procedure.
1) Reading: receives commands from the TSC and gets the optical powers of
monitored channels.
2) Confirmation: Sets up confirmation interval (0~300 seconds). To avoid false
alarm, after the confirmation interval, RTUs will automatically test channels
again. If the alarm is confirmed, RTUs shall send the alarm to the TSC.
