Before you calculate
Prepare a few project details for a better result.
The calculators are most useful when the route condition, device requirement and cable construction are already roughly known.
Route condition
Length, conduit size, bend count, indoor/outdoor route, aerial span, duct route, riser/plenum requirement and maintenance access.
System requirement
Power load, baud rate, optical budget, splitter ratio, device quantity, connector count, splice count and signal environment.
Cable direction
Category, AWG, fiber type, jacket, shielding, conductor material, OD, tensile requirement, certification target and packing request.
Quotation context
Quantity, project market, target standard, installation country, datasheet needs, sample plan and OEM/ODM marking requirements.
FAQ
Common questions before using ZION tools.
Keep the tool page focused: answer quick usage questions, then guide visitors to sales support when project confirmation is needed.
Are these calculators final engineering approvals?
No. They are practical pre-check tools for selection and quotation. Final cable construction, safety margin and installation approval should be reviewed against project drawings, standards and site conditions.
Which tool should I use for FTTH projects?
Use the FTTH / PON Splitter Loss Calculator when the main question is splitter ratio and ONU received power. Use the Fiber Optic Link Loss Budget Calculator when the route includes general connectors, splices, MPO/MTP or mixed fiber components.
Can ZION help select the actual cable after calculation?
Yes. Send the calculated result, route condition, required standard, quantity and target application through Sales Support so ZION can review the suitable product family and document requirements.
What information should be included in a support request?
Include cable type, length, route environment, system equipment, target country or standard, expected quantity, sample need, packing request and any tender or datasheet format requirement.
