Optical Amplifier Platform, 1724-Type
Erbium-Doped Fiber Amplifier (W Series)
Applications
■ Designed specifically for DWDM applications
■ Booster/power amplifier
■ Line amplifier
Description
The W1724-Type Erbium-Doped Fiber Amplifier
(EDFA) has been designed for use in DWDM applica-
tions and offers the following performance features:
■ Flat gain profile over a wide temperature range
■ Low noise figure
■ High output power
Designed for use in DWDM applications, the standard
W1724-Type EDFA incorporates a DB-25 connector and a
microcontroller with TTL compatible alarm monitoring.
■ 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. Optical input and output are
through single-mode fiber pigtails terminated with
optical connectors.
Features
■ Gain-flattened spectral response
■ High saturation output power, > 22 dBm
■ Low power consumption, < 12 W @ 45 °C
■ Low noise
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.
■ Single 5 V operation
■ Wide input signal bandwidth
■ Wide operating temperature range, 0 °C to 65 °C
■ Optical input and output taps
Contact your Account Manager at Agere Systems
Inc. to discuss electrical or optical connector options
not listed in the Ordering Information section.
■ Isolated input and output
■ Programmable input and output monitors
■ Connectorized single-mode fiber pigtail
■ Standard serial communication channels

Optical Amplifier Platform, 1724-Type
Erbium-Doped Fiber Amplifier (W Series)
Standard Features
TTL-Compatible Alarm Outputs
The standard W1724-Type EDFA incorporates the opti-
cal architecture illustrated in Figure 1. The standard
features include:
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).
■ Exceptional performance benefits with the integral
microcontroller, which precisely controls the gain to
maintain a flat spectral response over various input
powers.
Loss of Output Power Alarm
■ Single 5 V power supply eliminates the need for dual
voltage source circuits.
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).
■ DB-25 electrical connector allows for easy electrical
connectivity.
■ Optical input tap enables input monitoring and con-
trol.
Pumps Temperature Alarm
If the laser temperature for the pump(s) exceeds 35 °C,
the pump temperature alarm (pin 10) will activate (TTL-
logic 1).
■ SC/PC optical connector.
■ Low power dissipation.
■ Alarms:
— Loss of input power alarm.
Pumps Bias Alarm
— Loss of output power alarm.
— Pump bias alarm (>95% of EOL value).
— Pump temperature alarm (TL > 35 °C).
— EDFA temperature alarm (TC > 60 °C).
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).
■ Advanced microprocessor design requires minimal
engineering for a shelf-level product.
EDFA Temperature Alarm
■ 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.
If the case temperature exceeds 60 °C, then the
EDFA temperature alarm (pin 7) will activate (TTL-
logic 1).
Optional Features
Other feature and package options for the W1724-Type
EDFA include:
■ Alternative optical connectors
■ Integral heat sink

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. Normal = TTL low, alarm = TTL high if pump bias exceeds 95% of its end-of-life value.
4. Normal = TTL low, alarm = 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, alarm = 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.
