It's not a cable, it's a converter. USB and NMEA0183 are very different. You can get away with a cheapo USB to RS232 converter, but they are not NMEA0183 compliant. The NMEA0183 standard requires opto-isolation of the inputs and RS422 voltage level outputs which a cheapo USB to RS232 converter won't have. Hopefully this one does.

I have a couple of those cables which I have used to connect a Digital Yacht AIS into a plotter. and from the PC based nmea simulator on my PC to my Openplotter RPi. One I bought from RS Components the other from Aliexpress (or similar).
The spec you want is USB-RS232-WE-1800-BT 0.0
USB-RS232 - self explanatory
WE - wire ended
1800 - length in mm
BT - Black cable, Transparent plug (some come with a black plug but the advantage of the transparent one is that there are LEDs to show Tx/Rx activity).
0.0 - 0V on the red wire
I'd be happy to lend you one if you like.
