Apparatus for verifying the performance of optical fibre measurement equipment

摘要

Apparatus (2) for verifying the performance of optical fibre measurement equipment, comprising a housing (4), a length of optical fibre (6) in a main storage compartment (8), a first compartment (10) containing a first end (12) of the optical fibre (6) that is in the main storage compartment (8), and a second compartment (14) containing a second end (16) of the optical fibre (6) that is in the main storage compartment (8), the optical fibre (6) being stored under substantially zero tension, the first end (12) of the optical fibre (6) being a source end of the optical fibre (6), and the second end (16) of the optical fibre (6) being a detector end of the optical fibre (6).
