Misleading broken connector

Wednesday, October 23rd 2019, while troubleshooting an issue with my subwoofer, I discovered that one of my S/PDIF optical cable was disconnected; I found out the loose cable near my A/V receiver. This was previously used to send audio from my HTPC to my A/V receiver, before I got HDMI I/O on my new Yamaha receiver. I left the cable around in case the HDMI audio starts to fail, but it is kind of pointless as if I need to fall back on this, I would have to reconnect the HDMI cable directly on my TV as well. I wanted to either reconnect the cable or remove it altogether. However, I was unable to find back the optical connector on the receiver’s back. All I could find were RCA connectors.

Having a closer look at the back of the receiver, I discovered that one of the input had a broken connector in it. The connector looked like an RCA female but a bit different. The image below shows that connector.

After I discovered that and confirmed this was supposed to be the optical connector, I tried to remove the broken male connector from the female port using a plier. After a couple of attempts, I got the connector part back. It looks as follows.

The broken end of the cable looks as follows.

I was tempted to put the broken connector back on the cable.

By screwing the metal part back, it seems the connector is not broken. I didn’t test if it works. Maybe, or maybe it would be unstable.

That’s it. There’s nothing more to this!
