1738U-Type Small Form-Factor
Erbium-Doped Fiber Amplifier with Uncooled Pump
Applications
■ Single-channel links in:
— Metro systems
— Long-haul transport
— Switch matrix
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.
Compact size and extremely low power consumption make
the 1738U-Type EDFA an ideal solution for single-channel,
preamplification applications in C-band.
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.
