What is a LEMO fiber optic connector (also called SMPTE 304M connector)?

LEMO is both the name of an electronic and fibre optic connector manufacturer, based in Écublens, Switzerland, and the name commonly used to refer to push-pull connectors made by that company.

LEMO connectors are used in medical, industrial, audio/visual, telecommunications, military, scientific research and measurement applications. The company, founded in 1946, started as a manufacturer of contacts in noble and rare metals. The company took its name from the company founder, engineer Léon Mouttet.

LEMO has set several connector standards which includes the 3K.93C connector.

How to choose your fiber optic tester?

After the fiber cables are installed and terminated, it’s time for testing. You will need to test for continuityend-to-end loss and then troubleshoot the problems.

If it is a long outside plant cable with intermediate splices, you will probably want to verify the individual splices with an OTDR, since that’s the only way to make sure that each one is good.

In this article, we will introduce the most common types of fiber optic testers and their respective applications with videos showing the usage of each type.

How to calibrate your optical fiber power meter?

This is a testing setup developed by NIST to calibrate optical power meters using either collimated-beam or connectorized-fiber configurations.

This calibration system uses tunable laser diodes which operate in the three fiber optics windows of 850, 1310, and 1550nm.
