This course combines the NAVSEA 5 Day CAble Handling/Forming + BOF certification course with the General Cable BloLite BOF license certification course.
The first four days concentrates on the NAVSEA 5 Day Cable Handling/Forming certification component. This portion includes the “hands-on” instruction in the techniques and requirements for forming, shaping and routing Blown Optical Fiber (BOF) cable into Tube Routing Boxes (TRBs) and Distribution Boxes (DBs). Topics include: cable entrance to equipment (TRB and DBs), tube forming and shaping, interconnection organization, cable slack requirements, internal tube routing, box marking, BOF tube bend diameters, BOF tube end terminating (hands-on), multiple cable penetrators, nylon stuffing tubes, BOF outer jacket stripping exercise and use of tools (hands-on), forming and shaping into a TRB and DB (hands-on), installation of tube couplers and tees (hands-on), installation of jumpers (hands-on), sealing of BOF tube cables (hands-on) and protection from mechanical damage requirements.
The fifth day discusses the required BOF methods outlined in the NAVSEA Drawing #8477552 and described in the MIL-STD 2042(). The methods taught are as follows: Methods 2E1, 2F1, 2F2, 2F3, 2F4, 2M1, 6H1, 6I1, and 6J1. The balance of the day discusses the history and development of the BOF technology, discusses the advantages and applications of BOF and establishes the “hands-on” experience necessary to properly set up and use the special equipment associated with BOF. Each student will set up the BOF equipment, perform specific maintenance functions on the equipment, and conduct a pre-installation BOF pressure test and projectile test. Once these tests are completed, each student will successfully blow four fibers into the BOF cable plant and perform a seal verification test on a pre-existing terminated BOF cable plant. This portion of the course provides each student with the unique experience of troubleshooting an existing BOF cable plant with various preinstalled faults. Each student is required to determine the probable causes and correct the problems.
