Product Capabilities and
Value
Telecommunication systems using EDFA require optical isolators to
prevent unwanted feedback in the amplifier and to protect the laser
diodes. This component allows the light signal to pass through it
unattenuated in one direction (forward) while blocking it in the
reverse direction. WaveSplitter's polarization insensitive isolators
have low insertion loss, high isolation, low PMD, small package size,
and are Telcordia qualified. Small and large quantities are now
available for 1310, 1480, or 1550 nm wavelength operation.
