Compare OTDR and fiber test configurations
Compare equipment requirements for outside-plant, enterprise and FTTH/PON testing before selecting an exact kit.
Compare the test requirement before the tester. The three profiles below organize a supplier discussion; the project specification determines the exact instruments, modules and accessories.
| Decision | Outside plant | Enterprise / data center | FTTH / PON |
|---|---|---|---|
| Start with | Link lengths, splices and loss budget | Fiber type, short links and acceptance plan | Splitter topology and service state |
| OTDR selection | Appropriate singlemode module and range | Required SM/MM capabilities and event resolution | Module suited to the specific PON task |
| Loss testing | Follow the required end-to-end test plan | Check the required loss tests and reference method | Confirm the operator’s acceptance requirements |
| Complete kit | Launch/receive fibers, inspection and cleaning | Correct reference fibers and connector interfaces | Required ports, accessories and reporting |
| Operating question | Which wavelengths and directions are required? | Which reports must be handed over? | Dark or live fiber, and what method is approved? |
| Avoid assuming | Highest advertised range is always best | An OTDR replaces required loss testing | Every singlemode OTDR can test live PON |
Compare supplier proposals against one test brief
Send each supplier the same project requirements. Then record its response to each item below, with the quoted part number and any unresolved question. A feature shown on a product-family page is not proof that it is included in a particular quote.
- Shared requirements: fiber type, link lengths, connector types and polishes, service state, required wavelengths, test directions and the customer-approved acceptance plan.
- Exact hardware: platform and installed module for a modular system, or the complete model and configuration code for an integrated tester. Ask which ports perform each required measurement.
- Enabled functions: list the measurement applications and reporting software included at delivery. Identify any additional license, subscription or separate instrument needed for the specified work.
- Complete accessories: itemize launch and receive fibers, reference leads, adapters, inspection and cleaning equipment, power supplies and carrying equipment. Check each interface against the planned connection path.
- Customer deliverables: request sample native measurement files and exported reports from the proposed workflow. Check fiber identification, wavelengths, directions, test limits and the receiving customer's required format. Confirm which software opens the files and whether the quote includes it.
- Open items: mark each requirement as included, extra or awaiting confirmation. Record the supplier's answer, supporting document and quote revision before comparing delivered cost.
Why the platform name is not enough
VIAVI describes the T-BERD/MTS-2000 as a modular platform and lists different test modules and applications. Its optical power meter, visual fault locator and optical talkset are described as built-in options. Ask the supplier to identify the hardware and enabled functions in its actual proposal instead of treating every listed capability as standard.

Resolve the remaining questions before ordering
Use the EXFO MAX-730D configuration checklist when reviewing an EXFO proposal, and the connector worksheet for accessory details. If the measurement scope is unclear, start with OTDR versus loss testing: a report export does not by itself establish that the required measurements were performed.
When you send a configuration inquiry, include your test brief and the items still awaiting confirmation. Request written answers and a revised packing list before accepting a proposal.
Updated October 7, 2026. This worksheet is editorial buying guidance; supplier terms and configuration require confirmation.
Before comparing prices
Request the exact configuration, included accessories, freight, applicable tax, lead time, return terms and service route. Compare the same deliverables across proposals. Our focus is professional equipment purchases above $5,000; that budget is a buying criterion, not a quoted product price.
Purchasing starts with an inquiry. Configuration, availability, supplier terms and the service route need confirmation before an order can be accepted.
Test results must match the handover requirement
Ask which trace files and report formats the exact configuration can export. Confirm the installed measurement functions, software licenses and reference accessories. Use the project’s acceptance plan to establish what the kit must do.
