The Tektronix SD-43 is an optical-to-electrical converter for optical wavelengths from 700 to 1650 nm.
The bandwidth is 8 GHz.
It has an FC/PC connector for the optical input and a 2.92 mm ("K-style") connector for the electrical output.
The SD-43 can be plugged into an 11800-series mainframe next to an electrical sampling head, or used standalone with the 174-3867-00 adapter cable and a 119-5784-00 power supply.
