Description
The W1724-T ype 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 ■ Automatic gain lock The versatile W1724-T ype 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.

22 Agere Systems Inc. Data Sheet, Rev. 1 Optical Amplifier Platform, 1724-Type September 2001 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: ■ 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 (TC > 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. 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-T ype EDFA include: ■ Alternative optical connectors ■ Integral heat sink

- 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
the amplifier is turned on without the presence of an optical signal.
- Normal = TTL low, alarm = TTL high if input power is less than 2 dB below minimum P
- Amplifier enable (all pumps are on) = TTL low, amplifier disable (all pumps are off) = TTL high.
