Product Details Supplier Info More products

Laser Technologies has introduced the Modbox-850nm-28Gbps-NRZ optical reference transmitter from Photline Technologies. The optical modulation unit is designed for testing 100GbE systems and components.

It can be used as a reference transmitter for 100GbE conformance testing in optical telecommunications laboratories and in production test beds.

The turnkey Modbox-850nm-28Gbps-NRZ provides research and development engineers with high performance and ease of use, according to Laser Components.

Key information

  • The transmitter generates high-quality NRZ optical data streams.
  • Data rates are up to 28Gbps.
  • The device incorporates a 850nm laser source.
  • The modulation stage is based on a high-speed LiNb03 Mach-Zehnder modulator coupled with 40Gb/sec RF driver and automatic bias control circuitry.
  • It can also receive an optional photodetection stage.
  • Alternative modulation formats and wavelengths (1,310nm, 1,550nm and 1,060nm) are available.
