FOA CFOS/O study plan

Sketch a full outside plant route from a central office to a first splice point, labeling trench, duct, aerial, and building-entry segments with their depth or clearance requirements

List the physical forces and environmental loads (tension, bend radius, crush, water ingress, UV, temperature swing) that an OSP cable must survive, and state where each is controlled in installation

Compare direct-buried, duct, aerial, and submarine installation environments and write one paragraph per environment on what the installer must protect

Build a one-page glossary of OSP plant terms (handhole, pedestal, slack loop, splice closure, NID, conduit fill) and self-quiz until you can define each from memory

Classify at least six OSP cable constructions (loose tube, tight buffer, armored, toneable, figure-8, microduct) by jacket material, strength member type, and intended environment

Match each cable construction to the hardware it terminates into: closures, pedestals, handholes, aerial strand and lashing, and building entrance

Explain how water-blocking (gel vs. dry) and rodent protection change handling, storage, and splice practice

Practice identifying cable by reading a printed jacket legend and translate the legend into a compatibility decision for a given route

Calculate maximum pulling tension and minimum bend radius for three sample cables using their published specs, and state the safety factor you would apply

Sequence a duct-pull job end to end: mandrel and brush proofing, pull-line placement, lubricant choice, tension monitoring, and slack management

Describe air-blowing installation parameters (duct condition, cable stiffness, airflow, feed rate) and predict when blowing will stall

Draft a pre-installation site survey checklist that a crew lead would actually use before pulling or blowing cable

Demonstrate or verbally rehearse the correct use of pull grips, swivels, breakaway links, and figure-8 slack loops with a partner critiquing technique

Identify the confined-space, trenching, and aerial-work hazards on your practice route and match each to a control measure (shoring, gas monitoring, fall protection, traffic control)

Explain laser safety classes and when eye protection or optical power shutdown is required during placement and testing

Write the emergency response sequence for a cable strike, a fall, and an RF or optical exposure incident

Perform a fusion splice on loose-tube single-mode fiber and document cleave angle, splice loss estimate, and splice protection sleeve placement

Assemble a mechanical splice and compare its loss and rework characteristics against the fusion splice

Terminate a connector by both field-install and pre-terminated pigtail methods, then inspect each end with a scope and grade it against a standard pass/fail chart

Execute the wet-dry-clean inspection cycle and explain why dry cleaning alone fails on contaminated endfaces

Set a reference on an OTDR, choose pulse width and range for a 2 km and a 20 km span, and explain the tradeoff between dead zone and dynamic range

Interpret an OTDR trace by locating connectors, splices, bends, and a reflective event, and convert distance readings into physical fault locations

Perform a bidirectional loss test with a light source and power meter and calculate link loss budget against a design allowance

Diagnose three injected faults (dirty connector, tight bend, bad splice) from trace and loss data alone

Build a complete acceptance test package for the week 1 route: loss budget, OTDR baselines in both directions, and documentation fields required for handover

Calculate a link loss budget from component losses and compare it to measured values, flagging any span that fails

Locate a simulated break using OTDR distance, then verify the physical location against route records and slack accounting

Review workmanship against standard practices for cable support spacing, bend radius, slack storage, and closure sealing

Re-derive from memory the key numbers for each domain: bend radii, pulling tension limits, loss budgets, splice loss targets, and clearance depths

Complete a timed 60-question mixed practice set and categorize every miss by domain

Re-teach your three weakest subtopics aloud or in writing without notes, then correct the gaps you find

Assemble a one-page pre-exam reference sheet limited to what you can legally bring and what you must memorize
