Two 900um fibers with two SC/APC connectors. There is 30-pin electrical connector on the module. Manufacture test data (see last 2 pdf links below) show that it offers flattened 12dBm output power over full C-band, and low noise figure around 4dB. See year-2012 specification at the first pdf link and year-2007 specification at the 2nd pdf link below. We do not have other technical info and we do not have software codes/manual, you need figure out how to use it by yourself.
