Q: What is a universal port?
Q: Why are they called "universal" ports?
Q: Universal ports do not "latch in" like standard connector ports.  Will this affect my test results?

Q: Why is it okay to have interchangeable ports on power meters, but not okay for light sources?
Q: Why are interchangeable ports a bad idea for light sources?
Q: Why is it poor cabling practice to connect optical fiber links directly to equipment?
Q: Why is it impossible to measure insertion loss while connecting a fiber link directly to test equipment?

Q: What is a patch cable?
Q: Why are patch cables required for testing?
Q: Is there anything special about patch cables used for testing versus patch cables that connect active equipment to a link?
Q: What about "reference grade" patch cables?
Q: What happens if the port on my test equipment does not match the port in the patch panel?
Q: How do I choose the right patch cable?
Q: What about testing OM3 and OM4 50/125 fiber links?
Q: How many patch cables do I need for testing?
Q: What is a mandrel wrap and how does it benefit testing?
Q: What happens if I don't use a mandrel?
Q: I need to perform Encircled Flux-compliant testing.  Can I use regular patch cables for this?
