ADTRAN has applied its industry-leading carrier class
expertise to the OCU 45, creating a product that meets the
most stringent carrier class requirements.
The OCU 45 offers
transparent transport of T3/E3/STS-1 services over a fiber
transport, at distances up to 40km. The OCU 45 is available in
single-mode and multi-mode versions.
Measuring only one rack unit high, the OCU 45 can be used
standalone, wall mounted or mounted in 19-inch or 23-inch
racks using an optional mounting tray. This compact device
gives NSPs a convenient way to extend T3/E3/STS-1 services
from their point-of-presence to their customer and provides
enterprise users a powerful tool for extending T3/E3/STS-1
services over fiber in a campus environment.
Configuration of the OCU 45 is accomplished through two
switches on the front of the unit, which configure the
metallic inter-face to T3, E3 or STS-1 and sets metallic line
length to short or long. The OCU 45 has both normally-open and
normally-closed alarm relay contacts, with a front panel alarm
cutoff switch.
Diagnostics include metallic and optical Loopbacks
initiated via a front panel switch. Three LEDs monitor the
status of the metallic and optical interfaces.
The OCU 45 is DC powered from a -48 volt source. An
optional AC to -48 VDC converter is available to allow the OCU
45 to be AC powered.
