Fluke DSP-FTA440 Gigabit Multimode
Adapter
Networks running Gigabit Ethernet over multimode fiber
commonly use a new type of light source called a Vertical Cavity Surface
Emitting Laser (VCSEL). VCSELs are more cost-effective than conventional lasers
and it provide greater bandwidth than LED light sources.
The proper way to accurately test a fiber network using a
VCSEL is with a tester that uses a VCSEL. Meet the DSP-FTA440 the world's
first VCSEL-based Fiber Test Adapter.
Combining the DSP-FTA440S with
a DSP-4000 DSP-4100 or DSP-4300 provides automatic, dual-fiber loss
testing and certification by using a VCSEL laser at
850 nm and a Fabry-Perot (FP) laser at 1310 nm wavelengths. It also measures the
length of fiber links and certifies the results against the Gigabit Ethernet
standard.
In addition, the DSP-FTA440S allows bi-directional
testing on both fibers under test and saves results for both directions in the
same record. Utilizing Fluke Networks' comprehensive CableManager Software
you can easily save all fiber link data electronically for results management
and report generation.
Why do I need the DSP-FTA440S Gigabit Multimode
Fiber Test Adapter if I already have an LED multimode
tester?
- Networks running Gigabit Ethernet over multimode
fiber, use a light source called a Vertical Cavity Surface Emitting Laser
(VCSEL) for data transmission at 850 nm. More cost-effective than the
traditional laser, a VCSEL provides greater bandwidth than possible with LED
light sources.
With a VCSEL source, the light energy is concentrated in
the center of the fiber, whereas an LED source fills the entire fiber with light
energy. The farther the light energy is away from the center of the fiber, the
more likely it is to escape the fiber and show up as power
loss.
Therefore, when LED testers are used to test gigabit
multimode fibers, they tend to show more power loss than is actually present in
a network using a VCSEL transmission source.
With the very tight loss budgets for Gigabit Ethernet,
you could actually get a FAIL reading with an LED test, when the link is really
working. This could result in time wasted trying to fix a problem that doesn't
exist.
When you test with the VCSEL-based DSP-FTA440S, you can
be sure that you will see the actual loss that is present in the
network.
Can I test either 62.5 m m or 50.0 m m fiber with the
Gigabit Multimode Fiber Test Adapter?
- Yes. The DSP-FTA440S Fiber Test adapter contains a
50.0 m m internal launch fiber, so it is perfect for testing 50.0 m m fiber.
And it works just as well for 62.5 m m fiber because the light is being
launched from a smaller fiber (50.0 m m) into a larger fiber (62.5 m m),
capturing all of the light energy. This is true for both 850 nm and 1300 nm
wavelengths.
Does it matter what core size or type of patch
cord I use?
- Yes. The patch cord should always match the
core size and type of the fiber under test. A mismatched patch cord may cause
inaccurate loss measurements at the mismatched fiber-to-fiber
interface.
