United Optronics optical circulators are non-reciprocal devices that redirect light from port-to-port sequentially in only one direction. In advanced optical communication systems they are used for bi-directional transmission, WDM networks, fiber amplifier systems and optical time domain reflectometer (OTDR) measurements.
UOI circulators feature a small package, high channel isolation over a wide operational wavelength range, low insertion loss, low polarization dependent loss, low polarization mode dispersion and excellent stability.
- Low insertion loss

- Wide operating wavelength range
- Low PDL and PMD
- Long haul metropolitan and access networks
- Optical add/drop module
- Power equalization and
- Digital CATV
