Optical Amplifier Platform, 1724-Type

Erbium-Doped Fiber Amplifier (S and V Series)

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.

Standard Features

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 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).

The standard 1724-Type EDFA incorporates the optical

architecture illustrated in Figure 1. The standard fea-

tures include:

■ 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 con-

trol.

■ 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 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:

■ Alternative optical connectors

■ Integral heat sink
