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. |
