19. ANSI/TIA- 758-A Fiber Optic Cable • Bend radius shall be no less then 20 times the cable diameter during installation and 15 times after installation • Accurate OTDR tests require a minimum of 100 meters or 328 feet

20. What’s the purpose of standards? • To establish a basis to quantify, compare, measure or judge: capacity, quantity, content, extent, value, and quality • To promote interoperability of components and systems by multiple manufacturers.

21. Why do we have to know them? • To resolve potential disputes • Produce the results expected • Know when and where they apply

22. Key Areas of OSPPlanning and Installation Existing Buried Utilities • Staking / flagging / painting within 24” shall be considered a good mark • The potholing method will be used to determine the EXACT location of the utility before proceeding with construction • Potholing in road surfaces shall be no greater then 12” x 12”

23. Key Areas of OSP Backfilling the trenches • Can we use native soil? • Compaction? • Concrete encasement / capping • Flow-able Fill (Slurry) • Reseeding or Sodding

24. Key Areas of OSP Road or Parking Lot Excavation • Paved roads will be restored to original thickness or a minimum of ? thick • Areas that are excavated must be restored within ? hours • What method? Cut and restore, bore, casing, etc

25. Key Areas of OSP Handholes • Are used to aid in the placement of cables • Will not be used in place of a MH nor placed in a main conduit system • Will not be shared with electrical

26. OSP Handholes • Minimum size is a 4’ x 4’ x 4’ and larger sizes are acceptable (ANSI accepted?) • Will be equipped with lid, pull irons, cable racks, and hooks.

27. Key Areas of OSP Ducts • Duct shall be made of PVC • Shall be Schedule , EB, DB, RNC 40 or 60 RMC, HDPE, or IMC • Use 40 or DB if the duct is to be concrete encased or direct buried. (EB can be used only for concrete encased runs) • Use spacers every 5’ on all 20’ lengths of conduit (concrete blocks ?)

28. Key Areas of OSP • No more then two (2) 90 degree bends or a total of 180 degrees of bends between any two pulling points • Back to back bends should be avoided

29. Key Areas of OSP Rod and Mandrel • Existing vacant ducts, without pull strings, that are to be used for new cable installation shall be cleaned and tested with a mandrel. • Mandrel must be no more then ½” less then the ID of the duct. Mandrel must be non-flexible and be approx. 12 inches long

30. Key Areas of OSP Grounding (coming into buildings) • Ground wire must be a minimum #6 AWG • Must be done without sharp bends • Must be placed as short as possible • Must be 25 ohms or less (per NEC)

31. Key Areas of OSP Quality Assurance • Who does the OSP inspections at your institute? • Are they qualified or were they the one person that knew the most about OSP?

32. Safety Procedures All work performed will comply with: OSHA Occupational Safety and Health Administration
