Description:
The bow-type drop optic cable, is used for outdoor or indoor installation, includes central optical fibre(s) with 2 parallel FRPs as the strength members placed on both sides. It is easily strip and splice, simplified installation and maintenance. The non-metallic strength members to realize the tensile load. The optical fiber can be single mode and high silica material (based on ITU-T recommendation G652D, G657A1 and G657A2).
