The Agilent N3900A Modular Network Tester is a portable,
lightweight, rugged test platform for the installation, commissioning and
maintenance of optical networks. Developed from customer feedback from
installation and maintenance (I&M) technicians worldwide, its modular design
delivers the measurements you need, when you need them. Snap-on measurement
modules meet your test requirements for today’s communications networks; the
modular platform protects your investment, and lets you grow into your future
measurement needs.
The Modular Network Tester can hold up to three modules to perform OTDR
measurements, chromatic dispsersion, polarization mode dispersion or optical
spectrum analysis, or a 1x12 Optical Switch module. A video microscope camera
can be connected to ensure clean, fast and safe connector inspection as the
connector surface picture can be analyzed on the 10.4” display. From the
carrying case to the handles and tilt-stand, from the pop-up connector to your
choice of interface, attention to detail and to your feedback provide the
perfect fit for the way you work.
The Modular Network Tester is powered by a 64Bit RISC® processor architecture
with a real-time operating system, VXWorks®, for mission critical operations.
Each test engine has its own RISC processing power for ultra fast data
acquisition and high accuracy post processing. The Modular Network Tester boots
in one minute and all the modules can be hot-swapped – so it’s always ready to
work when you are.
Ergonomic design The Modular Network Tester feels like an extension to your
arm. It has a hand strap, an ergo grip, and a shoulder strap to work with you
and keep your hands free. Attaching a fiber optic connector to a test engine has
never been so safe and fast. The pop-up connector can be raised for connection
and cleaning purposes and sits securely in the down position, protected by a
dust cover while in transit.
The video microscope protects your eyes and speeds up your fiber optic
connector cleaning procedures. Flash-card data storage is rugged and secure –
there is no internal hard drive to crash. The Toolkit companion software,
Toolkit III, prepares acceptance reports the way your customers want them and
handles post-processing jobs to free you up for the next task.

The Agilent OTDR Module N3914AL works together with the
Agilent Modular Network Tester, and are easy to snap on. The OTDR application is
uploaded in seconds due to the dynamic software architecture, and allows plug
and play operation. Each OTDR test engine has built-in RISC processing power for
fast and accurate trace acquisition and data processing. These test engines work
in parallel processing mode with other connected test engines, for example, the
1x12 Switch module. All OTDR modules can be shared between multiple users,
without the need for any software changes.
- All Done. All Right. After the measurements have been taken the Pass/Fail
Test will automatically check for attenuation and insertion and return loss.
The new Bending Test will locate both macro and micro bends.
- Easy Connector access and protection. The pop-up connector solves many
common problems. For easy access to the optical fiber connection, the pop-up
connector is released to the up position, where a fiber can be attached
without any obstacles, or the connector cleaned. This also minimizes the risk
of scratches to the connector. In the down position with the dust cover
closed, the connector stays protected and clean during transit.
- Attach the right connector. Agilent's universal connector interface allows
a large range of standard fiber optic connectors, such as FC/PC, SC, and LC,
to be connected to the OTDR port. The connector interfaces are easy to attach,
even when working on site, and once removed, the fiber ferrule is easily
accessible for cleaning.
- Acceptance Test Done. The companion software, Toolkit III, prepares
acceptance reports the way your customers want them, and handles
post-processing jobs to free you up for the next task
