1480/1550 nm Polarization-

Insensitive Fiber Isolators

JDS Uniphase 1480/1550 nm Polarization-

Insensitive Fiber Isolators are specifically designed

for erbium doped fiber amplifier (EDFA)

applications. They provide stable, reverse isolation

at both 1480 and 1550 nm simultaneously. They

are insensitive to input light polarization and

epoxy-free in the optical path.

Key Features

Dual window coverage (1480 and 1550 nm)

High isolation

Low insertion loss

Epoxy-free optical path

Very low insertion loss and isolation stability

over temperature and wavelength ranges

High power handling capability

Applications

Optical fiber amplifiers

WDM network systems

Compliance

Telcordia 1221
