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.
