An ultraviolet (UV) light absorption sensing system () includes a UV light source () configured to provide a UV sample beam () of light toward a still or flowing fluid sample () along a central axis () of a test cell (), wherein the central axis () is substantially orthogonal to a direction of fluid flow. A reference light source () is configured to provide a reference beam () along the central axis () of the test cell (). A first detector () is positioned to detect a first portion () of the UV sample beam () and a first portion () of the reference beam () that traverse the test cell (). A second detector () is positioned to detect a second portion () of the UV sample beam () and a second portion () of the reference beam () directly from the UV light source () and reference light source ().

A method of laying an optical fiber comprises providing a continuous optical fiber, a first segment of optical-electrical hybrid cable having a first fiber receiving tube, and a second segment of optical-electrical hybrid cable having a second fiber receiving tube. The optical fiber is laid into the first fiber receiving tube using an air-blowing device. A leading end of the optical fiber is fixed in a transfer apparatus after the leading end passes through an outlet of the first fiber receiving tube. A portion of the optical fiber which has passed through the first segment is wound in the transfer apparatus until the optical fiber is completely laid in the first segment. The leading end of the optical fiber is detached from the transfer apparatus. The portion of the optical fiber which has passed through the first segment is laid into the second fiber receiving tube using the air-blowing device.
