Optical Amplifier Platform, 1724-Type
Erbium-Doped Fiber Amplifier (W Series)
Standard Features
The standard W1724-Type EDFA incorporates the opti-
cal architecture illustrated in Figure 1. The standard
features include:
s
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).
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 for 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.
— Pump bias alarm (>95% of EOL value).
— Pump temperature alarm (T
L
> 35 °C).
— EDFA temperature alarm (T
C
> 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.
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).
