The CORALIGN™ Difference

The CORALIGN™ portfolio of fiber optic switches utilizes the moving fiber design concept to achieve direct fiber to fiber connections.

The following configurations are available:

These singlemode fiber switches achieve their high accuracy through the use of the patented precision deflection structure that is at the heart of each switch.

A CORALIGN™ switch physically moves optical fibers to axially align with different optical fibers. The ability to produce a fiber optic switch void of collimating lenses, mirrors and the need for alignment fixtures is key to delivering competitively priced, quality switches. Luminos Industries has developed the custom in-house production equipment that delivers these results.

It should also be noted that, due to their low cost, these switches should be considered as a viable alternative for those applications traditionally handled by more restrictive fiber optic couplers.

Low Losses

The simplicity of the direct fiber to fiber connection through an air or oil filled gap allow CORALIGN™ switches to achieve the lowest insertion losses in the industry.

The low loss version uses indexing matching oil in the gap to achieve a lower insertion loss. In certain circumstances such as high power applications, oil cannot be used in the gap and we recommend using the normal loss version with an air gap.

Wavelength Independent

The elimination of any lenses in the moving fiber design mean the CORALIGN™ switch is wavelength independent and can handle any wavelength compatible with the fiber used.

High Power Application

Another advantage of the CORALIGN™ moving fiber design is that there is no epoxy or lenses between fibers, making it suitable for high power applications.

The singlemode switches can be used with powers as high as 20 dBm and the multimode switches can handle up to 23 dBm.

Drive Modes

Almost all switches (the center off 1x2 is an exception) have 2 possible "Drive Mode" options: latching or non-latching. The drive mode is specified by the part # when ordering and cannot be changed.

Latching Drive Mode

A latching switch requires a short electrical pulse to change state and will maintain the new state without power.

Electrical Connectivity
Pin State 1 State 2
1 V+ V=0
2 N/C
3 V=0 V+

Non-Latching Drive Mode

A non-latching switch is in state 1 with the power off and changes to the state 2 with power on. When power is removed, the switch reverts to state 1.

Electrical Connectivity
Pin State 1 State 2
1 Gnd Gnd
2 V=0 V=0
3 V=0 V+
