FIBER OPTIC CIRCULATORS

Polarization independent optical circulator is based on patent technology. It is marked with an
ultra compact package and high stability. It is an ideal candidate for FA, add/drop, dispersion
compensation and bi-direction transmission system.

Key Features:
• Low insertion loss and low cross talk
• Low polarization dependent loss
• Optical path epoxy-free
• Telcordia GR-1221-CORE compliance

Applications:
• DWDM and OADM networks
• Optical fiber amplifiers
• Fiber dispersion compensation and OTDRs
