Professional Equipment For FTTx & Metro Optical network Systems

As fiber optics plays more and more important role in modern telecommunication and CATV networks, the requirements to the construction, test and maintenance of fiber optics links also become more prominent.

FF-990PRO-Q1 is a unique product mainly designed for construction and maintenance of telecommunication and CATV networks. The FF-990PRO-Q1 OTDR can be widely used in engineering construction, maintenance test and emergency repair of all fiber optics related systems. Comparing with a regular OTDR, the FF-990PRO-Q1 OTDR is more compact in size and easier for field use.

FF-990PRO-Q1 OTDR handheld design, compact and lightweight, easy to carry. Event information through TFT color display and data storage capabilities. Through the USB interface, the test data can be uploaded to the PC, to facilitate the post-processing, archiving and printing.

: What is the operating system for the OTDR?
The operating system for the OTDR is Windows CE

Q: What Modules can be added for the OTDR.
A: The OTDR supports power meter module, light source module, micro scope module, able to add touch screen feature.

Q: How do I know which range to select on my OTDR
A: As for the OTDR support Auto testing mode, so it is able to automatically scan the network and set the range setting. The selected range is at least bigger than the total length of the launch cable plus the cable length under test, plus the tail cord. For best result and trace display in the OTDR, the selected length is better about 150% of the total length (total length = launch cable length + cable under test length + tail cord length).

Q: What Pulse width should use when testing the fiber
A: The key is to always use the shortest pulse width possible that will satisfy the trace quality and allow the user to see the end of the fiber. Short pulse widths are used for short fibers. Long PW’s are used on long fibers. If the trace quality exhibits excessive noise that cannot be removed by additional averages, select the next higher pulse width.
For the OTDR, please refer to the table below:
OTDR pulse vs distance

Q: What Adapters included by OTDR
A: The standard fiber adapter for the OTDR is FC, SC and ST. LC is for options.

Q: How to test a bare fiber
A: It is recommended to use a pigtail and mechanical splicer to test the bare fiber. Connect a pigtail of the correct fiber type and connector to the OTDR or far end of a launch cable. Cleave the opposite end of the pigtail and insert it into a mechanical splice. Cleave the end of your fiber to be tested and insert it into the opposite side of the mechanical splice. By using the "Real Time" function available on most OTDRs you can adjust the position of the fibers in the mechanical splice to get the best throughput. The cable is now ready to be scanned.

The certificate shows that a component/subsystem can be used in a specific application according to a requirement class (RC) or a integrity level (SIL). The system integrator and end user must always be aware of how to use certified components/subsystems in safety-related function, respectively a safety instrumented system. Because of the many different possibilities and how to configure a safety system, the end user must get the related information from the manufacturer of the certified component/subsystem.



The CE marking is a mandatory European marking for certain product groups to indicate conformity with the essential health and safety requirements set out in European. To permit the use of a CE mark on a product, proof that the item meets the relevant requirements must be documented.
