January 31, 2006 Daejeon, Korea -- Fiberpro says its Acoustic Fiber Cable Identifier (AFCID) Model CI 4000 is an easy-to-operate instrument designed for telecommunications engineers and technicians requiring a non-invasive method for identifying fiber-optic cables in manholes, tunnels, conduits, etc.
The company says that with the AFCID model CI4000 instrument, a user can easily recognize a particular optical cable by gently tapping on it. The tapping produces audio and visual detection in the system so that a technician can literally hear and see the targeted cable. The company notes that fiber-optic cable identification is a critical part of telecommunications maintenance and installation procedures, and must be done prior to cutting, splicing, and manipulating the main cable in circuit management applications.The company says its patent-pending AFCID instrument provides an outside plant technology whereby the optical fiber "becomes a microphone," enabling a non-invasive means of fiber-optic cable identification that does not require cutting, bending, and/or freezing of cabling. According to the company, the CI 4000 has a dynamic range of 50 dB that can potentially work on a loop back fiber span of up to 200 km. The device features a 6-dbm laser source at 1550-nm, as well as various signal processing options to allow technicians to work in noisy environments.
