1550nm Polarization-Maintaining Dual-Stage Fiber Isolator

IdealPhotonics‘ optical isolator products maintain excellent back-reflection isolation performance under any polarization state. They feature low insertion loss, high isolation, high return loss, low polarization-dependent loss (PDL), low polarization mode dispersion (PMD), a wide operating wavelength and temperature range, and an epoxy-free optical path. These characteristics make them a cost-effective solution for communication networks. This series of products is suitable for erbium-doped amplifiers, wavelength division multiplexing (WDM) systems, fiber optic equipment, and lasers.

Product features：Wide operating wavelength range & wide operating temperature range、 Low insertion loss & high isolation、 Low polarization-dependent loss and polarization mode dispersion、 Epoxy-free optical path、 Extremely high reliability and stability

Application area：Fiber amplifiers、 WDM & DWDM systems、 Fiber optic equipment、 Fiber lasers
