On receiving your new EDFA, you should carefully unpack and examine the contents for loss or damage that may

have occurred during shipping. Refer to warranty registration if loss or damage has occurred. The EDFA pack will

consist of the following:

Qty

Description

EDFA, Erbium Doped Fiber Amplifier

Product user manual (includes individual test sheet) (.pdf available)

Key for switching laser ON / OFF

Power supply cord

Keep all packing boxes and packaging of the EDFA for future transport.

Use only the original packaging of the EDFA when transporting. This packaging has been specifically designed to

protect the equipment.

The EDFA requires an input of 90 to 264 Vac or 30 to 72 VDC. The mains input socket on the unit is IEC

configuration which needs to be properly grounded. Over-load and over-voltage protection is included in the unit,

which may cause it to shutdown in extreme circumstances. If this occurs, remove the fault condition and the

system will recover automatically.

The unit should be located in an environment not exceeding a temperature range from 0 to 50 ºC. The internal

temperature should never reach 70 ºC. If the temperature exceeds the above limits, the unit should be relocated

in the equipment rack where the ambient temperature will be less than 50 ºC.

Horizontal, fan-forced airflow permits the mounting of multiple laser transmitters without the need for a 2 RU rack

space clearance between other devices. However to maximize the useful life of high power multiport EDFA, it is

highly recommended to keep space of 4.5cm in between chassis for optimized cooling. Ensure adequate space

behind the unit for ventilation as air flow is through the back of the unit.

The unit should have good grounding, grounding resistance<4Ω. According to the international standard, 220V

plug in adopts tri-wire rule, the middle wire is the grounding wire. Before connecting circuit, please use proper

electric wire (#20AWG or bigger) to connect the grounding screw on the bottom and the grounding frame. When

use DC input power supply, the equipment chassis must be grounded. The DC power supply of the equipment

must be the SELV supply stipulated as CAN/CSA C22.2 No.950-95 standard.

The following steps explain how the EDFA is to be installed. Please read them carefully:

Unpack the optical amplifier and inspect the unit as stated in Section 3.1.

Locate the optical amplifier in a 19” cabinet, ensuring adequate ventilation and space for

accessing the rear ports and front-panel keypad.

Prior to connecting any fiber patch leads to optical transmission equipment, always ensure

that the ends of the fiber optic connectors are clean and free of contaminants.

WARNING!

Do not view exposed fiber or connector ends when handling optical equipment. Exposure

to invisible laser radiation may cause permanent eye damage.

Connect the optical output ports to the system.

Always place protective dust caps on all optical ports when not in use.

Connect the optical input signal to the input port of the EDFA.

Ensure the input optical power is within the range of -10 to +10dBm with the typical value

at +3dBm.

Before connecting AC/DC power to the unit, make sure that the LASER ON/OFF key is

switched OFF (front panel).

Use the supplied power cord to apply mains power to the transmitter.

Switch the power ON (switch located on the front panel).

Switch on the laser using the key switch.

Front panel shows “KEY ON…”. Laser status lamp turns green from red, and the machine

enters self-checking. After checking, it enters working status and display “Descriptor”.

If the laser is not on, you will have to activate the laser and check that the output power is as

specified in the EDFA Certificate of Performance (COP). To activate the laser, see Section 5.3.

See Section 5 for instructions on how to view the status information about the EDFA.
