SMA Fiber Optic Patch Cable (200 micron, 0.5m)

This SMA fiber optic patch cable was taken from a larger instrument.  The connections may show minor markings and/or remnants of glue, but have been tested to thread smoothly on an SMA connection.  The fiber has been inspected visually using a microscope, and appears to be a 200 micron diameter step index fiber.  Transmission has been tested from 365 - 930 nm, and appears good over this range.
