Description (continued)
The versatile 1724-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 singlemode 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 optical output power. Contact your Agere Systems Inc. Account Manager to discuss electrical or optical connector options not listed in the Ordering Information section.
TTL-Compatible Alarm Outputs
Loss of Input Power Alarm
If the input power is more than 2 dBm below the minimum PIN, 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).
Standard Features
The standard 1724-Type EDFA incorporates the optical architecture illustrated in Figure 1. The standard features include:
s
Pumps Temperature Alarm
If the laser temperature for the pump(s) exceeds 35 C, the pump temperature alarm (pin 10) will activate (TTLlogic 1).
Exceptional performance benefits with the integral microcontroller, which precisely controls the output power and allows for changes to power settings as necessary. 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 control. 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. 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 (TL > 35 C) -- EDFA temperature alarm (TC > 60 C) Advanced microprocessor design requires minimal engineering for a shelf-level product. Standard mechanical outline includes metric screws
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).

Do not connect to reserved pins. Normal = TTL low, alarm = TTL high if the output power falls 2 dB below the minimum value. Normal = TTL low, alarm = TTL high if pump bias exceeds 95% of its end-of-life value. Normal = TTL low, alarm = TTL high if pump temperature exceeds 35 C. 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.
