12.5Gb/s光通信归零光发射机 机架式

The LT-RZ-12.5 series is an innovative electrical to optical designed for applications requiring Return-To-Zero (RZ) pulse generation and data coding. LT-RZ-12.5 provides RZ modulated optical source for high bit-rate transmission of ultra long-haul networks. LT-RZ-12.5 series transmitters utilize a narrow linewidth DFB laser source, optical pulse modulator (PM) and a broadband amplitude modulator (AM) to provide optically generated RZ waveform modulation. These products are ideal for DWDM or TDM digital transmission up to 13.0 Gb/s. It can also be an excellent product for electro-optic component characterization, DWDM networks, secure communication, laboratory test and measurement.

 

In addition to RZ modulation, LT-RZ-12.5 can also be set to generate Non-Return-Zero (NRZ) and pulse waveform. LT-RZ-12.5 series can be ordered with Single Mode (SM) fiber or Polarization Maintaining (PM) fiber. Its operating wavelength can be specified to any ITU DWDM grid within C-Band, at 50GHz channel spacing. The housing is a standard 1u height 19” rack mount. All LT-RZ-12.5 series products come with a standard 3 year limited warranty.
