FOA CFOS/DAS study plan

Map the FOA CFOS/DAS domain-1 outline into a personal checklist of subtopics, marking each item as known, shaky, or unknown

Define optical power budget terms in your own words: launch power, connector loss, splice loss, fiber attenuation, margin, and receiver sensitivity

Compute three sample link power budgets by hand at 850 nm, 1310 nm, and 1550 nm using published attenuation values

Set up a formula sheet and unit-conversion reference (dB vs dBm, mW to dBm) that you will reuse all eight weeks

Compare multimode and single-mode fiber types by core size, bandwidth, and typical reach, and justify a choice for three described campus scenarios

Calculate bandwidth-distance limits and modal dispersion effects for a given multimode link length

Select connector and splice types for indoor, outdoor, and high-density environments, stating one tradeoff for each choice

Sketch two physical topologies (star and ring) and annotate where redundancy and failure points sit

Explain how link-loss budgets feed into standards-based reach limits and where margin is deliberately reserved

Size a cable plant for a described building, estimating sheath counts, spare fibers, and pathway capacity

Identify documentation a designer must produce: loss budget, route map, fiber assignment chart, and as-built records

Distinguish design constraints that come from codes, environment, and customer requirements, and note how each changes the budget

Review your week 1-3 deliverables and close every subtopic still marked shaky or unknown

Draft a work breakdown structure for a fiber installation project, decomposing to tasks of one day or less

Sequence WBS tasks into a dependency network and identify the critical path

Estimate labor hours per task using a stated productivity assumption and flag the riskiest estimate

Build a project schedule with durations, milestones, and float, then identify which delays consume float versus move the end date

Define acceptance-testing criteria (insertion loss, ORL, length) and write them as pass/fail clauses

Plan a testing and commissioning sequence that respects when splicing, termination, and certification can occur

List safety and permit requirements that gate the schedule and state the lead time for each

Write a communication plan naming stakeholders, reporting cadence, and escalation triggers

Describe how to handle a change order: who approves, what gets re-baselined, and how cost and schedule impact is documented

Identify the records a project manager must collect for handover and explain why each matters to the owner

Practice a short verbal status update covering scope, schedule, cost, and risk in under two minutes

Re-derive two power budgets from memory and check them against your week 1 worksheet

Walk through a full project scenario end to end, from requirements to design to schedule to handover, noting where the two domains interact

Build a 30-question self-test mixing design calculations and project-management judgment calls, then score it

Revisit every item you missed and write the corrected reasoning in one sentence each

Condense both domains into a single review sheet of formulas, standards references, and decision rules

Complete two timed practice sets under exam conditions and record your pacing

Target your two weakest subtopics with focused re-study and re-test them

Restate the ten concepts you are least confident about and confirm each against a reliable source
