FIS2000 Remote Fiber Test System System Description

1

1 Overview

The FIS2000 Remote Fiber Monitoring Systemis designed to meet the need of cable

maintenance and management. The internal design / manufacturing, and control of crucial

RFTS technology ensure to offer the best solution. We aim for highest quality, humanizedtechnology, and good service to provide the advanced product. FIS2000 consists of OTDR and

OCS to monitor, test, and record optical fibers 7-24-365 without interrupting transmission.

Besides network monitoring, rapidly offering detailed fiber information and alarm location,

FIS2000 also performs multiple test modes, such as on-line test (Active Fiber), off-line test

(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.

The FIS2000 complies with general standards and regulations, such as

1. Bellcore GR-1309-CORE, TSC/RTU Generic Requirements for Remote Optical Fiber

Testing and Related Access and Test Messages.

Item Descriptions

TSC

Test System Controller. The TSC is installed in the system controlling

center. It can through DCN or IP-VPN receives alarms from RTUs andcommand RTUs to manage data, test fibers and so on.

WS

Work Station. The WS is installed at maintenance unit which means

the FIS2000 supports multiple work station environments; it can query

data and test fibers through TSC.

RTU

Remote Test Unit. The RTU is a test unit installed in equipment rooms

to test fibers. The RTU can accommodate MCU module, PSU, OTDR,

OCS, LSU, PMU, WDM, filter, splitter, etc.

OTAU

Optical Test Access Unit. The OATU is equipped with MCU and OCS.

The OTAU receives TSCs command to switch the otpical route to the

fiber under test.

PSUPower Supply Unit. The PSU is centralized power supply. It could offer

2 independent powers, DC(-36~-72V)+AC(11020V/22020V).

MCU

Monitor & Control Unit. The MCU is main control module of RTU. It is

responsible for RTU auto-monitoring, controlling test schedule,

analyzing and storing data, etc. With the MCU, the RTU can connect

and communicate with TSC by LAN (10/100 Base-T Ethernet). The

PSTN is also provided for redundancy.

OTDR

Optical Time Domain Reflector. The OTDR is the main equipment

module to test optical fiber. It is controlled by the MCU module. It sends

the testing signal to tested fiber according to test schedule.

OCS

Optical Channel Selector. The OCS is the optical switch module of

RTU. It is controlled by the MCU module to switch the optical channel to

the specified channel according to test schedule. Without OCS, RTU

could not test many optical fibers.

LSU

Light Source Unit. The LSU is a module of RTU, and it is composed of

major light source, redundant light source, coupler, splitter, etc. The

LSU is controlled by the MCU module. The TSC can remotely switch

the LSU to the major or redundant light source to emit the light. The

LSU is used in the off-line real-time testing architecture to offer the light

source to PMU so that PMU could real-time monitor the optical power.

Item Descriptions

PMU

Power Monitor Unit. The PMU is a module of PMU. It receives optical

power of monitored channel anytime. The PMU is controlled by the test

procedure; it can accept test command and issue optical power alarm.

WDM

Wavelength Divided Multiplexer. The WDM is a module of RTU, and

it is a passive component to multiplex or de-multiplex OTDR testing

wavelength (1550nm or 1625nm optical window) and transmission

wavelength (1310nm or 1550nm optical window).

FilterThe Filter is a module of RTU, and it is a passive component to filter

unwanted wavelength.

SplitterThe Splitteris a module of RTU, and it diverts 5% of received power to

the PMU for power monitoring.

Power of Optical

Channel

exceeds the major alarm threshold, major alarm will be triggered.

Threshold could be set by customer.

Minor Alarm

Threshold

When the variation of tested optical power and original trace reference

exceeds the minor alarm threshold, minor alarm will be triggered so that

maintenance can be made before transmission quality is affected.

Threshold could be set by customer.

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.


8/20

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.
