Many mechanical field terminable connectors use the 250 or 245 µm coding to restrain a cleaved fiber inside the back of shell of the connector, therefore if you have a 900 µm tight buffer you have a need to strip the 900um buffer from The 245um UV coating. Typically the amount of distance is about a centimeter. In many cases this need is called a semi tight buffer.
When mixing epoxy type terminations and field splice terminations one of the concerns is that using a loose tight buffer in an Epoxy connector can cause wicking of the epoxy back into the cable end many centimeters which will likely cause a fiber break near the connector backshell.
It is best to consider a specific strip test requirement when purchasing ”tight buffer” type cables based upon how and where you are using them. There are many more definitions than standards on tight buffer strip ability.
