Erbium-Doped Fiber Amplifier (S and V Series)
Optical Amplifier Platform, 1724-Type
Description
(continued)
The versatile 1724-Type EDFA operates over a wide
temperature range, exhibits extremely low power dissi-
pation, and offers a variety of alarms and monitors.
Optimum performance and system stability are sup-
ported 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. Sig-
nificant performance benefits are achieved with the
microcontroller, which stabilizes the temperature of the
pumps and maintains constant optical output power.

discuss electrical or optical connector options not listed
in the Ordering Information section.
Standard Features
The standard 1724-Type EDFA incorporates the optical
architecture illustrated in Figure 1. The standard fea-
tures include:
I
Exceptional performance benefits with the integral
microcontroller, which precisely controls the output
power and allows for changes to power settings as
necessary.
I
Single 5 V power supply eliminates the need for dual
voltage source circuits.
I
DB-25 electrical connector allows for easy electrical
connectivity.
I
Optical input tap enables input monitoring and con-
trol.
I
Optical output tap enables precise output monitoring
and control and, when used in conjunction with the
microcontroller, typically provides 0.2 dB of output
power stability over temperature and wavelength.
I
SC/PC optical connector
I
Low power dissipation
I
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)
I
Advanced microprocessor design requires minimal
engineering for a shelf-level product.
I
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 1724-Type
EDFA include:
I
Alternative optical connectors
I
Integral heat sink
