For internet service providers, fiber contractors and network procurement teams, acceptance starts before installation. The project needs a defined scope, measurable requirements and an agreed evidence package.
The Fiber Optic Association's guide to installation deliverables explains that a completed fiber project includes the installed cable plant, documentation and test results. It also recommends knowledgeable review of those records before sign-off.
This guide provides a practical checklist for the subscriber connection and its associated optical distribution network, or ODN. Apply it alongside the network owner's specification, approved equipment documentation and local installation requirements.
What Should an FTTP Acceptance Checklist Include?
Use the following table as a project template. Enter the actual specification reference and acceptance limit before assigning a pass or fail.
| Acceptance stage | What to verify | Evidence to retain |
|---|---|---|
| Scope and identification | Correct premises, work order, serving terminal and subscriber port | Work order and link identification |
| Site survey | Approved route, equipment positions, access and installation constraints | Survey record and annotated photographs |
| Pre-work approval | Authorized agreement to the proposed work and any changes | Dated approval record |
| Materials | Delivered components match the approved bill of materials | Model numbers, configuration and batch references |
| Cable installation | Cable support, bend control, entry protection and enclosure assembly | Installation photographs and inspection results |
| Connector condition | End faces inspected and contamination addressed | Inspection result and images where required |
| Optical testing | Required loss and power tests meet the agreed criteria | Instrument reports with test settings and limits |
| Service activation | Correct ONT registration and contracted service checks | Activation and service-test record |
| Defect closure | Failed items corrected and affected tests repeated | Defect log and retest evidence |
| Handover | Complete records reviewed by the responsible parties | As-built documents and acceptance status |
1. Complete the FTTP Site Survey Before Installation
A useful survey records enough detail for the installation team to follow the agreed plan without making avoidable assumptions.
Confirm:
- The premises address, work order and authorized site contact.
- The serving fiber access terminal and allocated subscriber port.
- The proposed external and internal cable routes.
- The termination box, optical network terminal (ONT) and router locations.
- Access to the installation area and suitable power for active equipment.
- Building-entry constraints, cable protection and maintenance access.
- The permissions and site-specific risk assessment required for the work.
Record the route as it will actually be installed, including changes of direction and entry points. This is particularly important when ordering a fixed-length, pre-terminated drop cable.
Approve equipment locations before work begins
Discuss where the ONT will be installed and how it will connect to the router. Equipment accessibility, ventilation and the customer's preferred router position should be considered together.
As an operator example, nbn's business FTTP installation guide describes approval of the installation plan before work starts and sign-off after installation. Its placement rules apply to the relevant nbn service; other operators should use their own approved requirements.
A practical project record should therefore distinguish approval to carry out the proposed work from acceptance of the completed installation.
Document building-entry decisions
Photograph the proposed entry locations and record the outcome of the applicable pre-work checks. Where the route cannot be approved, document the issue and obtain a revised plan before proceeding.
A public FTTP installation checklist hosted by SafetyCulture includes external and internal drilling-location images, detector evidence and an ONT optical-power record. It is a useful example of evidence fields, although its publisher identity and current operator approval should be verified before adopting it as a formal procedure.
2. Check Materials and Installation Workmanship
Acceptance becomes easier when the installed assembly can be compared with one approved bill of materials, or BOM.
For each connection, record the enclosure model, cable type, connector interface, connector polish, port allocation and any installed splitter. Identify substitutions before testing.
Inspect the installed cable path
Check that:
- Cable supports do not crush or visibly deform the cable.
- Routing follows the cable manufacturer's installation and operating bend limits.
- Entries protect the cable from sharp edges and uncontrolled movement.
- Glands, seals and unused-port closures match the specified assembly.
- Stored fiber remains clear of hinges, cover edges and fastening points.
- Splices and pigtails follow the documented tray and port map.
- Labels remain readable after the enclosure is closed.
The FOA fiber installation guide provides installation guidance covering cable handling, testing and documentation. Use the actual cable and enclosure instructions to establish the detailed workmanship criteria for the project.
3. Inspect Fiber Connectors Before Mating
Connector inspection should be part of the installation sequence and repeated when a connection is opened for testing or corrective work.
Use a suitable inspection system, address contamination with an approved cleaning method, and inspect again before mating. Confirm that the connector type and polish match the intended interface and test leads.
IEC 61300-3-35:2022 addresses visual inspection and classification of connector contamination and defects. The IEC explicitly states that visual inspection supplements optical performance measurements; it does not replace attenuation or return-loss testing.
For the acceptance record, identify the inspected interface, inspection profile, result and any corrective action. Handle persistent defects under the project's connector acceptance procedure.
4. Select the Correct FTTP Optical Tests
| Measurement | What it establishes | Key acceptance detail |
|---|---|---|
| Optical power, in dBm | Signal power at a defined measurement point | Wavelength, direction, measurement point and equipment-specific limits |
| Insertion loss, in dB | Attenuation across a defined optical path | Reference method, test wavelengths, path boundaries and allowable loss |
| OTDR trace | Event locations and the fiber path's backscatter profile | Direction, pulse settings, launch arrangement and interpretation |
| Optical return loss or event reflectance | Reflection-related performance | Required metric, method and applicable project limit |
Establish the optical acceptance limits first
There is no single ONT receive-power range that should be copied into every FTTP checklist.
Identify the deployed PON technology, optical class, OLT and ONT models, and the network owner's operating limits. Relevant system references include ITU-T G.984.2 for GPON physical-layer specifications and ITU-T G.9807.1 for XGS-PON.
The acceptance sheet should state both the applicable lower and upper power limits. It should also identify the approved measurement method and any required engineering margin.
Measure live PON power with suitable equipment
For common GPON deployments, the nominal downstream and upstream wavelengths are 1490 nm and 1310 nm. For the common XGS-PON wavelength plan, they are approximately 1577 nm and 1270 nm.
Where systems coexist on the same ODN, the meter must distinguish the relevant optical channels. Measuring upstream ONT transmission also requires support for the applicable burst-mode signal.
EXFO's guide to next-generation PON testing explains the need for wavelength discrimination, burst measurement and pass-through capability.
Record the meter model, calibration status, wavelength, direction and physical measurement point. A subscriber-side upstream reading must not be mislabeled as power received at the OLT.
Verify insertion loss against the defined path
Insertion-loss testing requires a light source and power meter, or an optical loss test set, with the appropriate reference procedure. The FOA outside-plant testing guide explains the distinction between absolute optical power and loss measurements.
For acceptance, document:
- The start and end of the measured path.
- Test wavelength and direction.
- Reference method and reference leads.
- Measured loss and the approved acceptance limit.
- Whether splitters, connectors and other passive components are included.
For example, if an illustrative project specifies a maximum installed-path loss of 24.0 dB, a measured 23.2 dB leaves 0.8 dB to that acceptance limit. This arithmetic does not establish a universal GPON limit or describe the complete system margin.
Plan intrusive tests around the service state and the network owner's approved procedure.
Use OTDR testing where the acceptance plan requires it
OTDR testing can locate events and provide a baseline trace for future fault investigation. A splitter complicates interpretation: downstream traces can combine information from multiple branches, while subscriber-side testing can make the selected branch easier to assess.
The FOA guide to FTTH testing discusses these effects and the trade-off between resolution and dynamic range.
Where OTDR records are required, save the original trace files and test settings. Use equipment and procedures suitable for the PON topology; in-service testing requires an approved arrangement compatible with the live network.
5. Record Service Activation Separately
After optical checks are complete, record the service tests specified by the operator.
A proposed activation record should include:
- ONT identity and assigned subscriber service.
- Registration status and relevant alarms.
- Confirmation of the intended service profile.
- Results of the required wired connectivity or throughput tests.
- Test device, connection method and test time.
- Any pending provisioning or customer-equipment issue.
State whether a throughput result was measured over Ethernet or Wi-Fi. This makes the result interpretable when the customer later reports a performance issue.
An installation can be physically complete while service activation remains pending. Record that status explicitly, with an owner and next action.
6. Assemble a Traceable Handover Package
The handover package should let another technician identify the installed path and understand how it was accepted.
The FOA Standard for Installing Fiber Optic Cable Plants treats documentation as part of design, installation and maintenance, including fiber routes and intermediate connections.
A practical subscriber handover package can use the following structure:
| Record group | Recommended contents |
|---|---|
| Link identity | Work order, premises reference, terminal ID, splitter output and ONT ID |
| As-built route | Actual cable path, entry points, termination locations and approved changes |
| Installed materials | Product models, loaded configuration, cable length and traceability references |
| Optical evidence | Required test reports, limits, settings, timestamps and original files |
| Installation evidence | Relevant photographs, inspection results and port labels |
| Exceptions | Defect description, responsible party, corrective action and retest result |
| Acceptance | Reviewer, date, decision and any expressly accepted outstanding work |
Use a consistent link ID across photographs, reports and drawings. Preserve the original failed result when a retest is performed so that the corrective action remains understandable.
For unresolved items, assign a clear status such as rework required, awaiting retest or service activation pending. Define any conditional acceptance process in the project documents.
7. Glory Optical Products to Consider for FTTP Projects
Select products according to their position in the fiber path and the records needed for acceptance. The following Glory Optical products address different parts of the subscriber connection.
GL-FTB-4F: A Compact Subscriber Termination Point
The Glory Optical GL-FTB-4F 2 Port Fiber Termination Box provides two adapter positions and capacity for splicing and storing up to four fibers. Its published configuration includes an IP65 enclosure and options for factory-installed connectors and pigtails.
Consider it for: a home, small-business or low-count building handoff where its port, splice and cable-entry capacities fit the design.
Specify before ordering: adapter format, APC or UPC polish, pigtail configuration, cable diameter, mounting accessories and port labels. IP65 is not a submersion rating.
Acceptance focus: verify that the installed internal configuration matches the approved drawing and that the cable-entry and port records are complete.
GL-FTB-10E: A Pre-Connectorized Fiber Access Terminal
The Glory Optical GL-FTB-10E FAT Pre-connectorized Terminal Box is listed as a 10-port terminal with Mini SC waterproof adapters and an IP65 enclosure.
Consider it for: planned above-ground access deployments using a compatible pre-connectorized distribution system.
Specify before ordering: the exact connector family, input/output allocation, splitter arrangement, subscriber-port count and mounting method. Confirm these in one approved drawing rather than deriving subscriber capacity from the enclosure's total port count.
Acceptance focus: match the installed port map and drop assemblies to the approved configuration. Confirm mating compatibility with the actual connector system before batch supply.
Pre-Terminated Fiber Optic Cable: A Defined Drop Assembly
Glory Optical's Pre Terminated Fiber Optic Cable includes configurable drop assemblies with specified lengths and termination options.
Consider it for: subscriber routes whose length, pathway and terminal interfaces have been surveyed.
Specify before ordering: fiber type, cable construction, both end interfaces, connector polish, finished length, permitted tolerance and protective packaging.
Acceptance focus: verify that the assembly reaches the approved endpoints without tension or unmanageable slack, and retain the agreed factory test evidence with the installation record.
For routes that may change during construction, review the trade-offs in Glory Optical's pre-terminated versus field-terminated fiber guide.
FAQ
What is the difference between FTTP installation acceptance and service activation?
Installation acceptance evaluates the agreed physical work, optical results and records. Service activation confirms that the subscriber equipment and provisioned service operate as required. Track both results separately.
What optical power is acceptable at an ONT?
Use the limits for the actual ONT, OLT optical class, wavelength and operator measurement procedure. A generic "good power" range does not establish acceptance for every GPON or XGS-PON installation.
Is an OTDR trace required for every FTTP connection?
Follow the network owner's test plan. OTDR requirements depend on the construction scope, topology and baseline records required. A new ODN build and a subscriber activation on an existing network may have different requirements.
Do factory-tested pre-terminated cables still need field checks?
Yes. Factory records describe the delivered assembly. Field checks verify its identity, routing, connector condition and installed performance under the project's acceptance procedure.
What should procurement request from a fiber component supplier?
Request an approved configuration drawing, BOM, interface details, relevant test reports, traceability information and installation instructions. Define the required documents before ordering so the delivered records can be matched to the project.
