4Cabling supplies a large range of fibre optic pigtails for splicing. 4Cabling’s ST Fibre 12 Pack Rainbow OM4 Multimode Pigtails (backward compatible with OM3) are used to connect high-speed networks like gigabit ethernet, fast ethernet and ethernet. The multimode pigtail buffer conforms to IEC, EIA TIA and Telcordia standards and is terminated with standard connectors which give optimum optical performance. These packs of 12 colour coded pigtail leads are used in patch panel terminations, with the fibre end of the pigtail being spliced onto the fibre run, and the connector is inserted in a coupler/adaptor on the patch panel. The connector on the pigtail has been pre-tested and certified in a controlled environment. This eliminates connector installation in the field which has major issues with regard to quality control and testing.
