Optical Line Identification patchcords

OLiD Assemblies

DIAMOND OLiD patch cables and pigtails are based on FBG (Fibre Bragg Grating) technology and are suitable for permanent installation in P2P fibre optic networks. They can be installed anywhere along a fibre optic line, however mainly in central office or in the Optical Termination Outlets (OTOs). Thanks to the FBG code written directly onto the fibre core, OLiD patch cables permit a clear optical line identification and prevent interference with standard P2P wavelengths. In a P2P network installation, this technology is used to identify the individual fibre lines and to manage the information using a network operator database.

The information can be called up using a DIAMOND OLiD interrogator. After installation, an acceptance test can be carried out where the correct and planned connection of all network sections can be verified. After line activation, the OLiD connections ensure that network failures can be discovered quickly, and support the rectification of the fault. Up to 48 different codings are available from the OLiD patchcords and pigtails. The main application is in FTTH networks for permanent line coding for line testing during a rollout.

The OLiD assemblies are available for connector types E-2000, F-3000 and SC. The custom cut ferrule is an 8° APC, where the OLiD system always works with single-mode fibres and the return loss of the line transitions must be kept low to be able to evaluate the reflecting OLiD signals.
