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.
