    Tight-length-tolerance patch cords

Patch cords with sub-millimeter length reproducibility

The length of an optical fiber cable is a critical piece of information. The most precise knowledge of such parameter is a mandatory requirement for applications in a variety of industrial and scientific domains: from interferometry to RF-over-fiber, from signal synchronization to optical metrology.

Upon custom request, Diamond offers patch cords produced with an enhanced-precision control on the fiber length. Optical cables up to 25 m can be fabricated with sub-millimeter reproducibility. Such tight length-tolerances are indirectly achieved through reflectometry measurements of the optical latency for short picosecond pulses.
