Optical Transmission

Preliminary data from LTSP150375
Standard cut-back attenuation on 253m segment

Annular Specifications

Annular core specifications are not finalized at this time.

Preliminary data indicates a minimum clad thickness of 9µm.

Interfacing and Handling

Cleaves like standard capillary. Optical quality cleaving or polishing required for optimum light input and output.

Polymicro’s FVP300330370 optical fiber closely matches the tubing OD of the initial products. This fiber offers a close match between the tubing annular core and optical fiber core. Smaller optical fiber can be used if spacing is adjusted to optimize light launch into the tubing. High-OH fiber is recommended; ask for our FV-Series optical fiber.

Contact Polymicro directly for a quotation on custom light guiding capillary assemblies. Please include a drawing or sketch of your proposed assembly.

Simple “T” style fittings have been used to make connections.

Special Note

Depending on the substance(s) introduced to the capillary interior, the light guiding properties can be modified significantly.
