SMA Connector Measurement - Measurement Equipment to Measure the Ferrule Length

[Mark Smith]

Does anyone know what measurement equipment can be used to measure the ferrule length on polished SMA connectors (for optical fiber)? The industry standard is 9.805 +/_ 0.005mm

Hve you tried a laser micrometer? I've had some good results to 4 decimals in mm. Need some technique and and fixturing. Is there a typical diameter?

I have a different SMA connector measurement question. Specifically for an SMA 905. I am having difficulty tracking down the standard that gives the ID specification for an SMA 905 connector. I have found IEC 61754-22 which replaced IEC 60874-2. Am I on the right track? These standards reference an F-SMA which I am not sure what the "F" stands for and I cannot be purchasing standards until I am fairly confident that I am on track. Any ideas will be appreciated? Thank you.

Welcome to The Cove Joules!

It looks like you are on the right track. I found the standard you mentioned for F-SMA type connectors on page 52 of this British standards list.

I couldn't find what the F means. Does anyone else out there know?
