Tactical 2 Cores 4 Cores Fiber Optic Patch Cord

As BBU/DU to RRU/AAU communication module units of outdoor communication base stations needs to use mechanically good performance to provide stable and reliable signal transmission connection in the outdoor environment. Therefore, tactical fiber optic cables with flame retardant and good mechanical properties are designed and manufactured with pre-terminated fiber optic connectors for BBU/DU, in DRAN mode, optical mode connection of equipment baseband board (e)CPRI interface or ODF unit of base station/outdoor cabinet, or passive wavelength division of the combined splitter port to BBU/DU equipment.

The optical patch cable is mainly composed of fiber optic connector and tactical optical cable, and its patch cable forming principle is to pre-terminate one end of the fiber optic cable on both ends of the fiber optic connector. Depending on the installation environment of different base stations, Bonelinks can provide armored and high tensile strength field fiber optic cables for selection. After determining the distance of the communication unit and the reserved length, first, cut the corresponding length of the tactical fiber optic cable, and design the length of the branch cable and the need for additional armor protection tube or pull-eye according to the requirements of the use; then extract the unit cable from the cut tactical fiber optic cable, peel off the outer skin and coating layer, and then insert the bare fiber into the LC or FC fiber optic connector filled with fixed glue. Fiber optic connector, through the connector curing, grinding, and end testing to complete one end of the cable and connector termination. At the other end of the cable, a complete fiber optic patch cord is pre-terminated by the same operation.

However, when the entire 2/4-core field fiber optic patch cable is pre-terminated and produced, it is necessary to continue to test whether the end face of the patch cable connector will be clean, whether the fiber optic cable can transmit signals through the light, whether the loss value of the entire patch cable meets the required standard, and whether the 3D test value meets the standard. When any one of the test data is abnormal, the entire finished patch cord needs to be reworked or even re-produced. After all test parameters meet the required standards, the product will only be arranged to be packaged and accompanied by test reports to one by one to show Bonelinks’ quality assurance of the product.
