Look to CertiFiber to test more fibers in less time. With its one-button
Autotest, CertiFiber allows you to measure fiber length and optical loss on two
fibers at two wavelengths, compares the results to the selected industry
standard and provides an instant PASS or FAIL indication. CertiFiber connects
easily to all fiber networks with interchangeable connector adapters.
Interchangeable Connector Adapters
CertiFiber's interchangeable connector adapters permit simple network
connection and a straightforward reference power measurement. Interchangeable
connector adapters are available in the most popular connector styles: ST, SC,
FC and 1.25mm universal.
Utilizing the 8240-04 CertiFiber's dual-fiber measurement method, when
placed in bi-directional test mode, CertiFiber measures the fiber pair in one
direction. It then prompts you to swap connections at the patch panel or outlet
and proceeds to measure the fiber pair in the other direction. Unlike the
traditional power meter and light source combination, you do not need to swap
CertiFiber's main and remote test units, providing tremendous time-savings for
each fiber link tested.
Using loopback mode, CertiFiber's main unit can function independently from the
remote. Loopback mode is useful when measuring a single fiber on a reel or spool
since both fiber ends must be near one another.
CertiFiber takes the guesswork out of interpreting test results. The length
and loss test results are automatically compared against a standard you
selected. The 8240-04 CertiFiber instantly provides a clear PASS or FAIL
indication for each fiber. The margin (or headroom) between the test measurement
and standards limit is also presented.
You can certify your network to various industry standards. Select the
appropriate standard from CertiFiber's built-in library. The library contains
the most common standards including TIA-568, ISO 11801, 10BASE-X and
1000-BASE-SX and it allows you to create your own custom test standards.
Length and Loss Measurement
CertiFiber measures fiber length using the "time of flight" technique where
an optical pulse is launched into the fiber under test. The time that it takes
for that pulse to return to its launch point is measured. This round-trip travel
time is also called propagation delay.
Since we know the speed of light in a fiber, it is simple to convert this time
into a length measurement. The advantages of this length measurement technique
include simplicity (no launch cables, no cursors to set) and accuracy,
especially with short lengths (zero dead zone).
CertiFiber also measures optical power and loss at 850 nm and 1300 nm and
reference measurements are easy to perform. Simply connect the main and remote
units, press the Set Reference button, and the 8240-04 CertiFiber automatically
measures and records the reference power for both fibers at both wavelengths.
CertiFiber cuts your test time by 75% over manual power meter techniques
while certifying your fiber links in seconds with a touch of the Autotest
The transmitter ports of the main and remote CertiFiber units incorporate dual
wavelength LED sources. Test both fibers at the multimode fiber transmission
wavelengths of 850 nm and 1300 nm. Dual wavelength testing occurs automatically
- no need to slow down to physically change transmitter adapters or manually
toggle between wavelengths. CertiFiber auto-senses the transmitted wavelength,
making testing even easier.
Every CertiFiber kit includes a pair of main and remote units. Both units
incorporate transmitter and detector ports. This unique configuration enables
testing of two fibers in a single operation. This design is ideal for testing
typical fiber links - a pair of Tx/Rx fibers. CertiFiber is also suitable for
testing dual-fiber Small Form Factor connector systems.
