CATV 1625nm Insensitive Optical Circulator Three Port Polarization
The 3 port optical circulator is a compact high performance light wave component that transmits the incoming signal from port 1 to port 2, while transmitting another incoming signal from port 2 to port 3. The component provides high isolation, low insertion loss, high extinction ratio, and excellent environment stability.
Features:
Low insertion loss
Wide band high isolation
Low PDL
Compact in-line package
High stability and reliability
Epoxy free optical path
Applications:
CATV system
Telecommunication network system
Metro/Access networks
Optical amplifier
Wavelength add / drop
Dispersion compensation
Bi-Direction communication
