• Supports OTDR and OTU 9500 Optical switch
The OTU-8000 Optical Test Unit lies at the core of the JDSU optical network management system (ONMS). Combining
optical time-domain reflectometry (OTDR) and optical switch technology, a single OTU-8000 unit can test hundreds of fiber
links within a 40,000 km2 area. When a fiber fault occurs, ONMS reports the location relative to the nearest landmark.
By deploying OTU-8000s in the central office, the telecom operator:
• Reduces operational cost by eliminating erroneous dispatches
• Reduces MTTR
• Anticipates service disruption by detecting fiber degradation before service is affected
• Protects the fiber investment by monitoring the long term performance of installed fibers
The modularity of the OTU-8000 enables it to fit all requirements for monitoring light or dark fiber optic networks.
Integrating the latest technology, it can monitor long haul as well as FTTx networks.
For organizations concerned with network security issues, the OTU-8000 can detect and locate fiber tapping inserting a loss
of a few tenths of a dB.

Overview
Reach new levels of reliability with the OTU-8000
The OTU-8000 is a rugged device designed to fit into the most stringent central
office. It uses no moving parts such as a magnetic hard disk to ensure the best
reliability. Its small size and low power consumption allows utilization where
space and energy are high value resources.
The dual power feeds provide an alternate power input in the event of one power
source failure. Additionally, all parts are field exchangeable without disconnecting
the fibers in an extreme case where it would be necessary to replace a part of the
OTU-8000.
Easy installation
Installing the OTU-8000 is a simple process. All connectors are located conveniently
on the front panel, and the unit is quickly mounted in either 19,” 21” (ETSI), or
23” equipment racks while occupying only two rack units of space.
Provisioning the OTU-8000 is accomplished easily using any Web browser, either
on site or remotely via LAN/WAN. The entire configuration is saved on the
OTU-8000 where it remains secure on a solid state disk.

Guaranteed alarm transmission
Thanks to its internal PSTN or GSM modem (optional) or the relay contacts
(option), the OTU-8000 can send alarms even if the LAN is not available. If the
server does not respond either by LAN or by modem, the OTU-8000 can also send
direct e-mail and SMS (with the GSM modem option) alarm notifications to
users. From any Web browser, users can access the OTU-8000 to view the local
alarm history and to carry out additional measurements.

Advanced fault location
The OTU-8000 combines fast scanning with accurate fault location. Fast
acquisition time is used to detect abnormal events. When detected the OTU-8000
switches acquisition parameters enabling high accuracy. The high resolution trace
is then processed to locate the fault. The fault location algorithum has been
improved for more than 15 years of JDSU’s experience in RFTS.

Compatibility
The OTU-8000 can be used to extend a deployment of OTU-9500, JDSU’s former
RTU. The same ONMS software will manage both. In addition, the OTU-8000 is
compatible with the OTU-9500 OTDR and optical switch. Thus, all the new
features are available simply by replacing the base unit. The OTDR modules
available for the MTS-8000 and MTS-6000 can be used with the OTU-8000. This
ensures coverage for a wide range of applications from FTTx to ultra long haul
network testing.

The OTU-8000 can house two field interchangeable OTDR
modules. A wide range of OTDRs are available, ensuring optimum monitoring of all types of fiber optic network from short
range multimode to long haul single mode.The OTU-8000
monitors active fibers using the 1625nm OTDR module which
is designed to take into account factors such as the Raman
effect of the optical amplifier.
The OTU-8000 can house a field interchangeable optical switch
module with up to 24 ports. If higher ports count is required,
24 ports can be extended to 48 or 72 ports by adding 1 chassis.
An OTU-8000 with no OTDR modules fitted forms the base of
the Remote Optical Switch controlled by TCP/IP.
The Remote Optical Switch base can be upgraded by adding an
OTDR module to become a complete OTU-8000 at any time.
