Inline Closure run through a FTTH network

You should ask the size of the ferrule being used; a smaller size improves the chance of concentricity (measure of how well Fiber Optic Splice Closure is centered in the ferrule). Some use a large 127 micron capillary, while a 125.5 improves this metric data as the core/cladding of a terminated fiber measures at 125.

Ask if epoxy is being de-gassed, especially if your patchcord will be used in uncontrolled environments like the OSP. What kind of prepping equipment do they use? The more automated equipment used, the smaller the chance of critical failures long term.

A manufacturing process can cheat the system by using manual and cheaper prepping tools. Manual prepping tools can cause nicks in fiber that could only become evident over time.

What kind of cleaving do they perform? Is it manual which requires a high level of skill achieved by years of experience? An automated process like a laser cleaver greatly improves first pass yield data and delivers a more repeatable performance process.

Your minimum requirements should include data that meets insertion loss and return loss (reflectance). Insertion loss should meet the 326-Core minimum of.4dB, with reflectance meeting 55dB for UPC connectors and 65dB for APC. Asking the typical performance measures of a manufacturer's process can save you on link loss budgets over a long Inline Closure run through a FTTH network.
