Description

The 1738U-Type Uncooled Small Form-Factor

Erbium-Doped Fiber Amplifier (SFF EDFA) is

designed for single-channel amplification in C-band

applications. The device is manufactured in an eco-

nomical SFF package and exhibits extremely low

power dissipation over a wide operating temperature

range.

Optimum performance and system stability are sup-

ported through the use of optical isolation at the input

and output. Optical input and output functions are

achieved through single-mode fiber pigtails termi-

nated with optical connectors. The EDFA incorpo-

rates an optical input tap and monitor photodiode.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-

lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess

of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended

periods can adversely affect device reliability.
