Start the passive path
OLT-side interface, feeder fiber count, cable route, ODF position, pigtails, adapters, splices, reserve fibers, and test baseline recorded together.
Solution / FTTH & PON access networks
Keep every passive interface visible from feeder to subscriber.
An FTTH bill of materials is easier to quote and install when the feeder route, split strategy, distribution points, drop lengths, connector polish, splice plan, port mapping, and optical acceptance record are built as one path.
Planning outcome
What the review should produce
A location-based ODN schedule that links every cable section, splice, splitter input and output, adapter, terminal port, drop connection, label, reserve, and test record.

Typical system map
Four layers to coordinate before the product list is final.
Map every branch
Centralized or distributed split, splitter ratio and package, input and output polish, cabinet or closure position, port map, and loss allowance defined before ordering.
Reach each service location
Distribution cable, closure branch, terminal-box capacity, drop cable type and length, route exposure, spare ports, and subscriber identification coordinated by address or service ID.
Close the installation record
Outlet or termination point, SC/APC connection, field or factory termination method, cleaning, inspection, optical test, labels, and exception record tied to the activated line.
Project inputs
Bring these six fields into the first review.
- 01OLT interface and optical budget basis
- 02Feeder, distribution, and drop route plan
- 03Split ratio, stage, and physical location
- 04Fiber counts, ports, premises, and growth reserve
- 05Connector polish, splice, and termination method
- 06Label map, test method, and handover format
Buyer questions
Decisions that change the bill of materials.
Should the splitter be centralized or distributed?
Compare feeder-fiber use, cabinet and closure space, access for maintenance, subscriber density, route lengths, growth areas, failure isolation, and the number of optical interfaces. Record the selected split stage and physical location on the same port map.
What belongs in an FTTH optical-path schedule?
List each cable section and length, fiber ID, splice, connector pair, adapter, splitter input and output, expected component loss, engineering reserve, test wavelength, acceptance result, and subscriber destination. Keep design values separate from measured handover results.
Can all SC connectors be treated as interchangeable?
No. Record UPC or APC polish at the ODF, splitter, adapter, terminal box, drop, outlet, and equipment port. The mating interfaces must match, and connectors should be cleaned and inspected before optical testing.
