Description
The W1724-Type Erbium-Doped Fiber Amplifier
(EDFA) has been designed for use in DWDM applica-
tions and offers the following performance features:
s
Flat gain profile over a wide temperature range
s
Low noise figure
s
High output power
s
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.
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:
s
Exceptional performance benefits with the integral
microcontroller, which precisely controls the gain to
maintain a flat spectral response over various input
powers.
s
Single 5 V power supply eliminates the need for dual
voltage source circuits.
s
DB-25 electrical connector allows for easy electrical
connectivity.
s
Optical input tap enables input monitoring and con-
trol.
s
SC/PC optical connector.
s
Low power dissipation.
s
Alarms:
-- Loss of input power alarm.
-- Loss of output power alarm.
-- Pump bias alarm (>95% of EOL value).
-- Pump temperature alarm (T
L
> 35 C).
-- EDFA temperature alarm (T
C
> 60 C).
s
Advanced microprocessor design requires minimal
engineering for a shelf-level product.
s
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 P
IN
, the loss of input power alarm (pin 19) will
activate (TTL-logic 1).
Loss of Output Power 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 for the pump(s) exceeds 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 feature and package options for the W1724-Type
EDFA include:
s
Alternative optical connectors
s
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. 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 P
IN
.
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.
