Musa connector

It has a characteristic impedance of 75 Ω,[1] and was adopted for use in the emerging television broadcast industry.

[2] The Musa connector was developed by the British Post Office, as a reliable and readily deployed means of achieving the desired configuration.

In such professional telecommunications and video applications, the connector performed well until the end of analogue (525 or 625 line) television.

The Musa connector was designed as to be rugged and reliable, typically using solid sterling silver contacts, and turned silver-plated brass or phosphor bronze bodies.

The historical choice of 75 Ω has turned out to be advantageous with the latest technology.
