Single Mode 1xN Polarization
Maintaining Fiberoptic
Coupler
Bandwidth ±50 nm
JDS Uniphase polarization maintaining fiberoptic
couplers rely on advanced micro-optics techniques
to split the optical signal into multiple paths while
retaining the original polarization orientation and
a high extinction ratio. The basic 1x2 coupler can
be cascaded in series to produce the 1xN products.
A wide variety of split ratios and port
configurations are available.
Key Features
High extinction ratio
Low excess loss
Broadband (±50 nm)
High power handling capability
Applications
Pump monitoring
Polarization maintaining optical system
