Product Details Supplier Info More products

The new DPSK reference transmitter from Photline Technologies is now available from Laser Components. The Modbox-1550nm-Gbps-DPSK high-data-rate reference optical transmitter is suitable for laboratory and production testing applications.

The Modbox-1550nm-12Gbps-DPSK is an optical modulation unit that generates high-performance DPSK optical data streams. It can receive an internal laser source (DFB or ITLA, for example) and a receiver stage based on a delay line interferometer and balanced detector.

The device — designed for research and development and production engineers — can be used as a reference transmitter in optical telecommunications laboratories, in test beds and in production.

In addition to the traditional 1,550nm wavelength range, it is also available at 1,310nm and for data rates up to 56Gb/sec. Modbox reference transmitters are also available for alternative modulation formats (DQPSK and NRZ) and as customised equipment.

Key features

  • Modulation stage based on LiNbO3 Mach-Zehnder modulator
  • High-performance radio-frequency driver
  • Robust automatic bias control circuitry
