Description

The W1724-Type Erbium-Doped Fiber Amplifier

(EDFA) has been designed for use in D WDM applica-

tions and offers the following performance features:

■Flat gain profile over a wide temperature range

■Low noise figure

■High output power

■Automatic gain lock

The versatile W1724-Type EDFA operates over a

wide temperature range, exhibits extremely low

power dissipation, and offers a variety of alarms and

monitors. Optimum performance and system stability

are supported through the use of optical isolation at

the input and output. Op tic al input and outp ut are

through single-mode fiber pigtails terminated with

optical connectors.

The EDFA incorporates optical input and output taps

that are monitored via an integral microcontroller.

Significant performance benefits are achieved with

the microcontroller, which stabilizes the temperature

of the pumps and maintains constant gain of the

amplifier.

Standard Features

The standard W1724-Type EDFA incorporates the opti-

cal architecture illustrated in Figure 1. The standard

features include:

■Exceptional performance benefits with the integral

microcontroller, which precisely controls the gain to

maintain a flat spectral response over various input

powers.

■Single 5 V power supply eliminates the need f or dual

voltage source circuits.

■DB-25 electrical connector allows for easy electrical

connectivity.

■Optical input tap enables input monitoring and con-

trol.

■SC/PC optical connector.

■Low power dissipation.

■Alarms:

— Loss of input power alarm.

— Loss of output power alarm.

— P ump bias alarm (> 95% of EOL value).

— Pump temperature alarm (TL > 35 °C).

— EDFA temperature ala rm (TC > 60 °C).

■Advanced microprocessor design requires minimal

engineering for a shelf-level product.

■Standard mechanical outline includes metric screws

and fiber outputs (using SC/PC optical connectors)

at 180 degrees relative to a DB25 electrical connec-

tor. The standard product does not include a heat

sink.

TTL-Compatible Alarm Outputs

Loss of Input Power Alarm

If the input power is more than 2 dBm below the mini-

mum PIN, the loss of input power alarm (pin 19) will

activate (TTL-logic 1).

Loss of Output Powe r Alarm

If the output power decreases by more than 2 dB from

its beginning-of-life value, the loss of output power

alarm (pin 8) will activate (TTL-logic 1).

Pumps Temperature Alarm

If the laser temperature f or the pump(s) e xceeds 35 °C,

the pump temperature alarm (pin 10) will activate (TTL-

logic 1).

Pumps Bias Alarm

If the bias current for the pump(s) exceeds 95% of its

EOL value, the pump bias alarm (pin 9) will activate

(TTL-logic 1).

EDFA Temperature Alarm

If the case temperature exceeds 60 °C, then the

EDFA temperature alarm (pin 7) will activate (TTL-

logic 1).

Optional Features

Other f eature and package options f or the W1724-Type

EDFA include:

■Alternativ e optical connectors

■Integral heat sink

Pin Information

1.Do not connect to reserved pins.

2.Normal = TTL low, alarm = TTL high if the output power falls 2 dB below the minimum value.

3.Norm al = TTL low, alarm = TTL high if pump bias exceeds 95% of its end-of-life value.

4.Norm al = TTL low, alar m = TTL high if pump temperature exceeds 35 °C.

5.The EDFA is equipped with an optical transient suppression feature when this pin is tied to GND. The EDFA will turn all pumps off, if the

input power is too low. Tying this pin to 5 V will disable this feature; however, damage to the optical connectors and components may occur if

the amplifier is turned on without the presence of an optical signal.

6. Normal = TTL low, alar m = TTL high if input power is less than 2 dB below minimum PIN.

7. Amplifier enable (all pumps are on) = TTL low, amplifier disable (all pumps are off) = TTL high.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-

lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess

of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended

periods can adversely affect device reliability.
