Optical Network Tester 40/43 Gb/s Test Solution
Key Features
Optical transport networking
New 40/43 Gb/s networks will allow operators to further enhance transport capacity in the
optical network, extend distances between systems, and improve its flexibility and responsiveness in setting up new high-bandwidth services as well as lowering operating costs for
these services.

Market drivers
High-end core routers with 40 Gb/s short reach interfaces are becoming an important
market driver, reducing the number of interconnecting fibers within the central office. Big
benefits are the lower cost, space and power consumption. In long-haul networks, a key
to 40 Gb/s migration is the ability to utilize the existing line system. In metro-regional networks, e.g. city-hoppers applications, 40 Gb/s can also be used very cost effectively.
Challenges
New, high bit rate networks create enormous challenges for equipment vendors not only
because they push the boundaries of physics, but also because every network component
must be perfectly designed, installed and tuned. The point at which networks are installed,
turned up and commissioned will prove critical. A new generation of test equipment
capable of meeting the demands of 40/43 Gb/s systems will be required at each stage of
network design, system verification and validation, network installation, maintenance, and
troubleshooting.
Optical transport test solution
The JDSU ONT-506/512 enables evaluation and characterization of 40/43 Gb/s electrical/
optical devices. The ONT supports unframed BER testing, and framed SDH/SONET/OTN
functional testing including jitter/ wander generation and analysis. The modular concept
starts with 3 slots for 40 Gb/s optical framed and unframed. Further modules can be added
to enable electrical interfaces and jitter/ wander applications. In addition, the programmable hardware architecture allows to add a payload module for the combined OTN with SDH/
SONET client testing and to assure the future-proof for further applications.

Interfaces, storage, data transfer
The ONT-5xx use a Pentium PC as internal controller allowing to run
Linux applications as well.
Interfaces Ethernet (RJ45), 4 x USB,
External keyboard, mouse, VGA, DVI
CD R/W/DVD-ROM drive for data transfer and software update.
PC Pentium M, 1.8 GHz, 1 GB RAM
Hard drive for data/setup storage ≥ 40 GB
Remote control for test automation
The ONT-503 is controlled remotely via SCPI commands sent by the
customer’s program using an Ethernet TCP/IP or a GPIB connection.
The GPIB connection is possible via USB-GPIB cable, provided by
National Instruments.
Modules are addressed independently and in parallel and may be
shared among multiple users. In case of GPIB only one module can
be addressed.
Universal driver libraries facilitate automation with specific support
for individual applications.
Scripting support via Tcl/Tk and C libraries and LabWindows drivers.
The interactive GUI also works in parallel to remote control, so that
it is very easy to develop automated scripts.
