Optical-to-electrical converters

These optical-to-electrical converters provide characterizing, debugging, and verifying for standards compliance of sonet/sdh/oc-1/stm-0 through oc-48/stm-16 optical communications signals when used with the tds 500c/700c digital storage oscillioscopes. The SD-44 15-GHz O/E converter characterizes the pulse shape of optical signals to 2.488 Gbits/sec. The orr24 is an amplified 2-GHz O/E converter with a built-in fourth-order Bessel-Thompson frequency response. The converter is calibrated at 1310- and 1550-nm wavelengths and includes a frequency-response graph that certifies a controlled frequency response out to twice the data rate (5 GHz). The SD-44 is priced at $5995 and the orr24 at $10,495.
