C-Band Optical Circulators

Selected Features

• Low insertion loss across the C-band
• High isolation and low PDL, PMD
• Broad wavelength range resulting from patented design
• Tested to Bellcore standards
• Epoxy-free optical path for high-power handling

We are offering optical circulators for use in WDM networks. Based upon the Faraday effect, these non-reciprocal devices direct light from port-to-port in only one direction. These circulators have low insertion loss, and high isolation over a wide wavelength range. Moreover, by using a proprietary optical design and packaging technique, we keep the optical path epoxy-free, resulting in increased reliability. Each circulator offers minimal polarization dependent loss (PDL) and polarization mode dispersion (PMD).

Selected Applications

• Bi-directional EDFAs
• C-band and dual C+L-band EDFAs
• Add/drop multiplexing
