Connecting the Fiber Optic Interface

This module includes Class 1 lasers. For your safety:

• Do not look directly into the optical connectors while the module is operating.

Remember that the module starts operating as soon as it is inserted in an

operating DXC system.

• Do not attempt to adjust the laser drive current.

The use of optical instruments with this product will increase eye hazard. Laser

power up to 1 mW at 1300 nm and 1550 nm could be collected by an optical

instrument. The laser beam may be invisible.

Use of controls or adjustment or performing procedures other than those

specified herein may result in hazardous radiation exposure.

The fiber optic interface terminates in ST, FC or SC connectors, designated TX and

RX.

 To connect the fiber optic interface:

1. Remove the protective caps from the connectors and store them in a safe

place for later use.

2. Connect the transmit fiber to the connector marked TX and the receive fiber

to the connector marked RX.

3. At the remote unit connect the transmit fiber to the connector marked RX

and the receive fiber to the connector marked TX.

Connecting the Power

The units have no power switch. Operation starts when the power is applied to

the rear panel POWER connector.

Before switching on this unit and connecting any other cable, the protective

earth terminals of this unit must be connected to the protective ground

conductor of the mains power cord. If you are using an extension cord (power

cable) make sure it is grounded as well.

Any interruption of the protective (grounding) conductor (inside or outside the

instrument) or disconnecting of the protective earth terminal can make this unit

dangerous. Intentional interruption is prohibited.

For the AC version, make sure that only fuses of the required rating, as marked

on the rear panel, are used for replacement. Do not use repaired fuses or short-

circuit the fuse holder. Always disconnect the mains cable before removing or

replacing the fuse. Whenever it is likely that the fuse protection has been

damaged, make the unit inoperative and secure it against unintended operation.
