FTTH / PON Access Network Solution
FTTH Total Solution for PON Access Networks
Build a coordinated OLT-to-ONT passive network with eight core product families: PLC splitters, fiber distribution boxes, fiber optic adapters, fiber pigtails, fiber patch cords, fast connectors, drop cables and fiber termination boxes. ZION also supports product selection, optical-interface matching and quote-ready BOM planning.
Build the FTTH BOM by network layer, not by one cable name
Split point
Match PLC splitter ratio, insertion loss, connector type and enclosure layout to the optical budget.
Access terminal
Select FAT box or terminal box capacity according to subscriber density, mounting method and maintenance access.
Subscriber drop
Use FTTH drop cable or pre-terminated drop patch cord based on field labor, routing distance and connector quality control.
Build the material list from OLT to ONT
1. Freeze the design basis
- Homes passed, forecast take rate and phased subscriber growth
- PON type, split ratio, centralized or distributed splitting, and optical budget
- GIS route length, aerial/duct/direct-buried/indoor sections and access-point locations
- Project rules for spare fibers, spare ports, material reserve and restoration stock
2. Quantify OLT to ONT components
- ODF, feeder cable, joint closures, cabinets and primary splitters
- Distribution cable, secondary splitters, FAT/FDB/NAP units, adapters and pigtails
- Drop cable or pre-terminated drop assembly, outlet box, patch cord and ONT lead-in
- Splice sleeves, cable clamps, mounting kits, labels, earthing and route-specific hardware
| Network layer | Typical start and end | Quantity driver | BOM control |
|---|---|---|---|
| Feeder cable | OLT/ODF to primary split or distribution hub | PON ports, topology, route diversity and growth reserve | Keep feeder fibers traceable by service area; do not size it from subscriber count alone. |
| Distribution cable | Hub or closure to FAT/FDB/NAP | Terminal service areas, splitter placement and spare fibers | Schedule each branch separately so closures, trays and terminal ports reconcile. |
| Drop cable | FAT/FDB/NAP to customer outlet or ONT | Connected premises, actual drop route and installation method | Separate installed drops from future connection stock; use standard length bands where practical. |

Size fiber, closures and material reserve as one coordinated plan
Calculate demand before applying reserve
Convert the approved split architecture into active feeder and distribution fibers, then add restoration, growth and route-diversity fibers. Select the next available standard cable size only after documenting those inputs. A percentage by itself is not a complete FTTH feeder fiber count rule.
Count splices by closure location
For each closure, list incoming, outgoing, branch, pass-through and splitter-pigtail splices. Required splice tray quantity equals planned splices divided by usable splices per tray, rounded up, plus the project reserve. Confirm cable ports, fiber storage and splitter space separately.
Use risk-based ratios by item
Apply the FTTH spare material ratio by failure and replenishment risk: cable allowance for measured route and handling, extra connectors and small accessories for installation loss, and dedicated restoration stock for long-lead closures or terminals. Do not apply one blanket percentage to every line.
| Planning decision | Recommended method | Check before release |
|---|---|---|
| FTTH spare fiber ratio | Define active fibers first; add named growth, maintenance and restoration fibers, then round to a standard fiber count. | Every spare fiber has a purpose and remains within closure, tray and terminal capacity. |
| Fiber closure capacity | Use the greater constraint from splice count, cable-entry count, stored-fiber volume, splitter accommodation and future branch requirement. | Quoted capacity means usable project capacity, not only the enclosure's headline splice rating. |
| FAT vs FDB vs NAP | Treat names as regional conventions. Compare function: splitter housing, splicing, adapter ports, sealing, mounting and subscriber access. | The schedule states required functions and port configuration instead of relying only on the acronym. |
| FTTH drum length planning | Map each pull section, add installation slack and joint allowance, respect maximum pulling length, drum capacity, transport limits and site sequence. | No planned mid-span joint; each drum is assigned to a route section and has an approved remainder plan. |
| FTTH material optimization | Standardize cable sizes and drop-length bands, consolidate accessories, reconcile BOM to drawings, and reuse acceptable drum remainders on shorter approved sections. | Optimization never removes optical margin, restoration stock or installation slack. |

Common issues to clarify before placing the FTTH order
Optical budget is not checked
Splitter ratio, connector count and route distance should be reviewed together instead of selecting only by price.
Drop cable is over-simplified
Different subscriber routes may need different strength members, sheath options or pre-terminated assemblies.
Terminal capacity is too small
FAT box and terminal box capacity should reserve enough ports for maintenance and user growth.
Connector details are unclear
SC/APC, SC/UPC, LC interface and adapter loading should be confirmed before splitter and patch cord quotation.
Questions buyers usually confirm for FTTH / PON access products
How do I build an FTTH passive-material BOM?
Freeze homes passed, take rate, PON topology, split locations and mapped route lengths. Schedule OLT-to-ONT components by network node, calculate cable and port quantities, add documented installation and restoration reserves, and reconcile every line against drawings before issuing the RFQ.
What components are needed from OLT to ONT?
A typical passive path includes ODFs, feeder cable, splice closures, cabinets or hubs, PLC splitters, distribution cable, FAT/FDB/NAP terminals, adapters, pigtails, drop cable or pre-terminated drops, customer outlets and patch cords. Add route hardware, splice sleeves, labels, mounting and earthing items as required.
How should feeder, distribution and drop cables be separated?
Separate them by function and endpoints: feeder connects the OLT/ODF to a hub or primary split point; distribution connects that point to access terminals; drop connects an access terminal to one premise. Give each segment its own route, construction, fiber count, unit length and reserve rule.
What fiber count should be used in an FTTH feeder cable?
Calculate working fibers from the selected PON and split architecture, then add explicit fibers for growth, maintenance, restoration and any route diversity. Round the result to an available standard cable size and verify that ODF, closure and tray capacities support it.
How much spare fiber should be included?
There is no universal percentage. Set the FTTH spare fiber ratio from growth forecast, repair strategy, route criticality, build phases and the operator's design standard. Record both the percentage and the actual spare-fiber count so the reserve remains visible after rounding.
How should closure capacity be selected?
Count all current and planned splices, cable entries, pass-through fibers, stored fiber and any splitter modules at that exact location. Choose a fiber closure capacity that accommodates the worst of those constraints with the approved expansion margin and compatible cable seals.
How many splice trays are required?
Divide the total planned splices in the closure by the usable splice capacity of the selected tray and round up. Add the project reserve, keep splitter or ribbon requirements separate, and confirm the enclosure can physically accept the resulting splice tray quantity.
What is the difference between an FAT, FDB and NAP?
The acronyms vary by market. FAT usually emphasizes subscriber access termination, FDB emphasizes distribution and splicing, and NAP identifies the network access point. Specify the needed splitter, splice, adapter-port, sealing and mounting functions because product names alone are not reliable selection criteria.
What spare ratio should be included in an FTTH BOM?
Set separate reserves by material type and risk. Cable needs route, slack and handling allowance; connectors and small hardware need an installation-loss allowance; long-lead enclosures may need restoration stock. State the basis and round to the supplier's pack quantity rather than adding one percentage to the whole BOM.
How do I reduce FTTH material waste?
Reconcile the BOM to the latest route drawings, standardize fiber counts and drop-length bands, assign every drum before shipment, consolidate compatible accessories, and track acceptable remainders for approved short sections. Preserve optical margin, installation slack and restoration stock while optimizing.
How should fiber drums be divided for an FTTH project?
Divide drums by continuous pull section, cable type, installation sequence and delivery zone. Add section-specific joint and installation slack, observe drum and transport limits, label each drum to its route, and avoid an unplanned splice simply to use a generic drum length.
How should reel length be planned for FTTH construction?
For FTTH reel length planning, start with surveyed section length and add approved slack at closures, poles, chambers and equipment. Check pulling tension, bend limits, access points, reel capacity, vehicle handling and installation order, then plan how any usable remainder will be allocated.
