UNIT OVERVIEW
The ADTRAN OCU 45 offers transport of T3/E3/STS-1 services over a
fiber transport up to distances of 40 km in the single-mode version and 2 km
in the multi-mode version. Measuring only one rack unit high, the OCU 45
can be used stand-alone, wall mounted, or mounted in 19 or 23-inch shelves
using an optional mounting tray. This compact device gives NSPs a conve-
nient 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 interface to T3, E3 or STS-1
and set the metallic line length to short or long. The OCU 45 has both nor-
mally-open and normally-closed alarm relay contacts with a front panel
Alarm Cutoff Switch (ACO).
Diagnostics include metallic and optical loopbacks, initiated via a front
panel switch. Three LEDs are located on the front panel to monitor the sta-
tus of both the metallic and optical interfaces.
The OCU 45 is powered from a -48V source. An optional AC to -48Vdc
converter is available to allow the unit to be AC powered.

FRONT PANEL FEATURES
The OCU 45 front panel provides switches and LEDs to offer easy configu-
ration and troubleshooting (see Figure 1-1). The three switches set the con-
figuration for the electrical interface, electrical line length, and loopback test
options. The LEDs indicate the status of the power supply, the electrical
interface type and line length, loopback diagnostics, and electrical and opti-
cal interface status. A brief description of the LEDs is as follows:
•ThePOWER LED shows that the unit is receiving power.
•TheINTERFACE LED indicates the current electrical interface configura-
tion.
•TheLINE LENGTH LED indicates the current electrical line length con-
figuration.
•TheTEST LED indicates that there is an active loopback at the electrical
or optical interface, or that the unit is in normal operation.
•TheELECTRIC LED indicates the current status of the electrical inter-
face.
•TheOPTICAL LED indicates the current status of the optical interface.

REAR PANEL FEATURES
The OCU 45 rear panel provides electrical and optical interface connections,
normally-open and normally-closed alarm relay contacts, and a 48V power
connection (see Figure 1-2).
The electrical interface connector is provided using dual 75 Ohm BNC female
connectors (one for transmit and one for receive). The optical interface of the
OCU 45 consists of a standard SC or ST receptacle using two fibers, one for
each direction of transmission.
External alarm contacts for critical and non-critical alarms are provided on the
rear panel of the OCU 45 using a standard 4-pin terminal block containing
NORMALLY OPEN, NORMALLY CLOSED, COMMON, and GROUND
connections. The DC power supply connector is a standard 3-pin terminal
block containing -48V, RETURN, and GROUND. For more information on
the above connections, please refer to Installation on page 2-21.
