Isolators & Circulators
Our 980/1550 nm WDM/Isolator Hybrid is a combination of a filter and a 1550 nm polarization insensitive optical isolator. It is a low-cost model with excellent performance, including low insertion loss, high isolation, high return loss, low polarization-dependent loss (PDL), and low polarization mode dispersion (PMD). This product offers an integrated solution to EDFA application by combining more functions into a very compact package. All our products are Telcordia qualification tested.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
980/1550nm WDM/Isolator Hybrid: Laser source protection depends on preserving the optical budget through the complete path. The 980/C Band, 980/L Band, T1550/R980 wavelength specification sets source and detector compatibility. The fiber/interface entry (HI1060/SMF28, Special) must match the connected components.
980/1550nm WDM/Isolator Hybrid: Bidirectional signal routing depends on preserving the optical budget through the complete path. The 980/C Band, 980/L Band, T1550/R980 wavelength specification sets source and detector compatibility. The fiber/interface entry (HI1060/SMF28, Special) must match the connected components.

Technical FAQ
Fiber: HI1060/SMF28, Special · Fiber cover: Bare fiber, 900um Loose tube, 250um, Special. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: 980/C Band, 980/L Band, T1550/R980. Check the Isolators & Circulators passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
