By using thin membrane plating technology in collimating lens, we successfully manufacture a 16×10Gbit/s multiplexer
basing on the combination of fiber and space structure method. The multiplexer is flexible according to your practical
need that can output 20, 40, 80, or 160Gbit/s signal. For 20, 40, 80 or 160Gbit/s multiplexer, insertion loss is 3.5dB, 7dB,
10.5dB and 14dB respectively. The low insertion loss provides maximum transmission power. It also has such features:
high time-delay accuracy, polarization insensitivity, broadband, very short coherence length, high time-delay accuracy,
and excellent temperature stability. It differs from the structure of general Mach-Zehnder interferometer. It has the
structure of Michelson interferometer.
