WaveSmart Fiber Circulators

Provides fiber relief for applications that currently utilize a unidirectional dual fiber transmit/ receive configuration, using either 1310nm or 1550nm wide band optics or Sonet/Ethernet optics (discrete, SFP, XFP). Note: SFP or XFP systems may be better served using a WDM solution.

Product Details

The WaveSmart Circulator allows the user to reroute the traffic that traditionally required two fibers (one for each direction of travel) onto a single fiber with bidirectional traffic. This in turn allows the user to reduce the number of required fibers from two to one (four to two for working/protect systems).

Packaging Options

Clearview Cassette

The Clearview Cassette provides four optical devices in a single high Clearview Cassette or up to 36 input/output ports of any optical component device(s) of your choosing in a three high cassette. The Clearview Cassette then populates any FieldSmart product across the network, including inside plant panels, outside plant cabinets, and access network products, such as pedestals and wall mount panels.

Clearview xPAK

A compact and convenient means by which to land up to seven input/output ports of any optical component device. It can be deployed as a stand-alone device or integrated into a Clearfield designed enclosure or many industry-leading enclosures from the provider of your choosing.


For those service provides who have standardized on the LGX style, Clearfield provides the standard circulator devices in the LGX footprint which can be integrated within a Clearfield supplied LGX chassis or a LGX chassis of your choice.


Provides an unpackaged solution to integrate wave division technology into the fiber optic enclosure of your choice. Units are available pre-terminated or un-terminated with 250um, 900um, or 2mm “legs”.
