Photline Technologies has introduced its new ModBoxTTX, a benchtop tunable laser source designed for laboratory and production use. The ModBoxTTX offers a 1MHz resolution over 40nm of wavelength tunability in either the A band, the C band or the L band. It delivers a comfortable 13.5dBm (optional 15.5dBm) output power of highly pure (100kHz linewidth) light from a polarisation preserving outptut fibre.

The ModBoxTTX is controlled from a PC through an intuitive graphical user interface. Several high speed modulation options are proposed with the source 10Gb/s, 40Gb/s, and a DQPSK make it a versatile high performance instrument.
