1.1 Scope of this Manual

This document describes the form, fit, and function of the OptiCaT 1500 Series
Erbium-Doped Fiber Amplifier (EDFA) and all acceptable standard options.

• Installing the unit

• Operating the unit

• Setting up the unit to suit individual needs

• Troubleshooting

• Theory of operation

• Repair Policy

1.2 General Description

The OptiCaT 1500 EDFA is an optical amplifier operating in the 1550 nm
wavelength region. These units are intended to function as either a booster or line
amplifier depending on the model.

980nm diode lasers are used to pump Erbium doped fiber to provide optical
amplification. Depending on model, optical isolators are used at both the input and
output of the amplifier. Tap couplers allow the measurement of the optical input
and output powers.

The unit can be powered from AC, DC, or conditioned external DC supplies,
configured as main or backup, depending on which powering option is ordered.

1.3 Physical Description

Figure 1-1 is an illustration of the OptiCaT 1500 EDFA, showing unit
measurements. The Optical Amplifier is a rack mounted 1U unit.

Height 1.75" (44 mm), 1U
Width 19" (483 mm)
Depth 20" chassis (508 mm), 21" (533 mm) with fans
Weight 20 lbs (9 kgs) max.
