Uniformity, directivity and polarization-dependent loss describe different behaviours and must not be replaced by a single insertion-loss value. Lot acceptance should define the method, wavelengths, sample plan and disposition rule before shipment.<\/strong><\/p>\n

Uniformity compares output-port loss spread; directivity concerns unwanted coupling in the reverse direction; PDL describes loss variation with polarization. Values depend on the stated configuration and method. Buyers should request raw port-level data and a product-specific specification rather than transferring limits from an unrelated package or split ratio.<\/p>\n

How to Control PLC splitter uniformity directivity PDL in the Project<\/h2>\n

Les commandes ci-dessous \u00e9tablissent un lien entre le plan, l'\u00e9chantillon, le lot de production et le r\u00e9sultat de l'installation. Elles sont d\u00e9lib\u00e9r\u00e9ment ax\u00e9es sur la praticit\u00e9 : chacune d'entre elles g\u00e9n\u00e8re un document que les \u00e9quipes des achats, de l'ing\u00e9nierie et du terrain peuvent consulter ult\u00e9rieurement.<\/p>\n

Keep parameters separate<\/h3>\n

Report insertion loss by port, calculate uniformity from the defined set, and record directivity and PDL under their specified methods. A pass label without the underlying fields is not auditable.<\/p>\n

Freeze methods before results<\/h3>\n

Agree wavelengths, launch, connectors, reference procedure and environmental condition in the purchase specification. Do not change a method after viewing a difficult lot.<\/p>\n

Use a declared sampling plan<\/h3>\n

Choose the sample size and acceptance rule from the relevant inspection system and contract. AQL is a process for lot disposition, not a promise that every untested unit meets the limit.<\/p>\n

Investigate patterns<\/h3>\n

Look for repeated weak port positions, package lots or connector types. Pattern review can find assembly or mapping problems that a simple pass count misses.<\/p>\n

A useful splitter certificate connects defined parameters to raw port data, equipment, sample identity and a pre-agreed lot decision. Keep all of those records under the same part revision.<\/p>\n
