Integrated Polarization Maintaining Fiber-Optic WDM/Isolator (PMWDM-SPFI/SS)

 

Description:

 

The polarization maintaining (PM) fiber-optic WDM/isolator combines the functionality of a PM isolator (1550nm) with a PM-WDM in one compact inline package thus providing significant advantages performance, size, and cost. This integrated hybrid product features high isolation, low insertion loss, high extinction ratio, high return loss, and high thermal stability in a compact design. A range of WDM multiplexing is available.

 

 

 

Applications:

 

·         EDFA (PM)

·         External modulator transmitters

·         Fiber lasers

·         Fiber sensors

 

 

Key Features:

 

·         High isolation

·         Low loss

·         High thermal stability

·         High extinction

·         High return loss

·         Compact inline package, 5.5mm OD
