The TOSA meets the requirements of the XMD MSA. It consists of a high speed electro absorption modulator monolithically integrated with a DFB laser in a hermetic package, which also includes an isolator, a monitor photo diode and a micro thermoelectric cooler. The TOSA, which comes with a connectorized single-mode fiber pigtail and is equipped with a flexible printed circuit (FPC) for electrical interconnections, is available in wavelengths covering the full C-band on ITU-T 100GHz channel spacing.
